Shungite Nanopowder as a Modificator of Mechanical Properties and Water Absorption for Three-Ply Particle Board
Materials Science Forum, 2016Co-Authors: Sergey Borisovich Vasilyev, Gennady Kolesnikov, Aleksandr Vasilyevich Pitukhin, Nikolai Gennadievich Panov, Vadim KostyukevichAbstract:The article presents the methods and the results of the experimental investigation of the additive influence of shungite nanopowder when mixed in the glue for three-ply Particle Board. The hypothesis of shungite nanopowder influence on physical-mechanical properties, water absorption and thickness swelling of wood Particle Board was formulated. The results of experimental investigations proved that the optimum shungite nanopowder quantity in glue solution makes up about 10 % of absolutely dry resin mass. Wooden Particles of aspen and coniferous species, as well as glue solution based on carbamide-formaldehyde resin, were used in Boards manufacturing. The samples were tested in order to determine physical-mechanical properties. It was found out that the 10 % shungite nanopowder additive increases the breaking point of three-ply Particle Board under bending strength by 18.3-25.7 %, the breaking point of three-ply Particle Board under tension perpendicular to the face of Board by 7.5-11.7 %. As the result of experimental investigation it was found out that the 10 % shungite nanopowder when mixed in the glue decreases water thickness swelling of three-ply Particle Board up to 14.2 % and water absorption by 10.6-20.1 %. The shungite nanopowder powder contained Particles of 50...100 nm in size and specific surface of 120 m2/g. In the course of the experiment three-ply Particle Boards were used with the thickness of 15.6 mm.

Do wood-based panels made with agro-industrial residues provide environmentally benign alternatives? An LCA case study of sugarcane bagasse addition to Particle Board manufacturing
The International Journal of Life Cycle Assessment, 2014Co-Authors: Diogo Aparecido Lopes Silva, Francisco Antonio Rocco Lahr, Ana Laura Raymundo Pavan, Yovana M. B. Saavedra, Natalia Crespo Mendes, Sabrina Rodrigues Sousa, Roberta Sanches, Aldo Roberto OmettoAbstract:Purpose Sugarcane bagasse is one of the main agro-industrial residues which can be used to produce wood-based panels. However, more investigations related to its environmental performance assessment are needed, focusing on questions such as: Does it provide environmental benefits? What are its main environmental impacts? Could it substitute wood as raw material? Accordingly, this paper presents a life cycle assessment (LCA) study of Particle Board manufactured with sugarcane bagasse residues. Methods The cradle-to-gate assessment of 1 m^3 of Particle Board made with sugarcane bagasse (PSB) considered three main subsystems: bagasse generation, bagasse distribution, and PSB production. For the inventory of PSB, dataset from two previous LCA studies related to the conventional Particle Board production and the ethanol life cycle for the Brazilian context were used. The allocation criterion for the bagasse generation subsystem was 9.08 % (economic base). The potential environmental impact phase was assessed by applying the CML and USEtox methods. PSB was compared with the conventional Particle Board manufactured in Brazil by the categories of the CML and USETox, and including land use indicators. Finally, two scenarios were analyzed to evaluate the influence of the allocation criteria and the consumption of sugarcane bagasse. Results and discussion All hotspots identified by CML and USETox methods are mainly related to the PSB production subsystem (24–100 % of impacts) due to heavy fuel oil, electricity, and urea-formaldehyde resin supply chain. The bagasse generation subsystem was more relevant to the eutrophication category (75 % of impacts). The bagasse distribution subsystem was not relevant because the impacts on all categories were lower than 1 %. PSB can substitute the conventional Particle Board mainly because of its lower contribution to abiotic depletion and ecotoxicity. Regarding land use impacts, PSB showed lower values according to all indicators (38–40 % of all impacts), which is explained by the lower demand for land occupation in comparison to that of the traditional Particle Board. Conclusions PSB can replace the traditional Particle Board due to its better environmental performance. The analysis of the economic allocation criterion was relevant only for the EP category, being important to reduce diesel and N-based fertilizers use during sugarcane cultivation. Regarding the influence of the sugarcane bagasse consumption, it is suggested that the sugarcane bagasse be mixed up to 75 % during Particle Board manufacturing so that good quality properties and environmental performance of panels can be provided.

characterisation of tannin resin blends for Particle Board applications
Cement & Concrete Composites, 2003Co-Authors: E T N Bisanda, W O Ogola, J V TeshaAbstract:Abstract Tannins and cashew nut shell liquid (CNSL) are groups of natural resins that are receiving wide attention as substitutes to synthetic binders in the production of biocomposites. In this work, blends of hydrolyzed tannin, CNSL, and urea formaldehyde (UF) have been tested to determine their mechanical and physical properties for Particle Board applications. The blending of hydrolyzed tannin with UF resin has been found to reduce the formaldehyde emission levels significantly. A blend of hydrolyzed tannin and CNSL has been found to possess better dimensional stability. Tannin-blended resins cure faster, i.e. have shorter pot life, and result in composites with better water and moisture resistance when compared to UF. Thermal analysis by differential scanning calorimetry has shown that tannin blends exhibit better thermal stability and have a higher glass transition temperature than UF resin. Generally, it was found that Particle Boards made from coffee husks, and bonded using the tannin resin blend that include UF and CNSL, possessed superior properties to those made using UF alone. The mechanical and physical properties of coffee husk-Particle Boards produced using this new resin blend are presented and discussed.

Catalytic copyrolysis of Particle Board and polypropylene over Al-MCM-48
Materials Research Bulletin, 2016Co-Authors: Hannah Kim, Suek Ju Choi, Ji Man Kim, Jong-ki Jeon, Sunghoon Park, Sang-chul Jung, Sang Chai Kim, Youngkwon ParkAbstract:Abstract Particle Board and polypropylene (PP) at a mixing ratio of 1:1 were copyrolyzed over two Al-MCM-48 catalysts with Si/Al ratios of 20 and 80. The catalyst characteristics were examined by measuring the Brunauer-Emmett-Teller surface area, temperature programmed desorption of ammonia, and X-ray diffraction. The main pyrolysis products of Particle Board were oxygenates, acids, and phenolics, whereas a large quantity of hydrocarbons within the diesel fuel range was produced from copyrolysis with polypropylene. The catalytic copyrolysis of Particle Board and PP over the Al-MCM-48 catalysts produced bio-oil with a much larger hydrocarbon content than that from the catalytic pyrolysis of Particle Board only. The hydrocarbons produced were mainly in the diesel range, highlighting the potential for the production of high-quality fuel.

analytical pyrolysis properties of waste medium density fiberBoard and Particle Board
Journal of Industrial and Engineering Chemistry, 2015Co-Authors: Chuichi Watanabe, Norio Teramae, Youngkwon ParkAbstract:Abstract Medium-density fiberBoard (MDF) and Particle Board (PB) showed similar pyrolysis characteristics. Thermogravimetric analysis displayed the main weight loss between 200 and 400 °C, continued up to 600 °C. The activation energy (Ea) values at each conversion were in the range of 166–372 kJ/mol for MDF and 161–325 kJ/mol for PB and indicated independent reactions of hemicellulose, cellulose, lignin and char stabilization. Isothermal pyrolysis produced hemicellulose pyrolyzates at 300 °C. The main products at 400 °C had similar distribution between MDF and PB. At 600 °C, gas products were increased due to the secondary cracking of pyrolyzates.

Catalytic co-pyrolysis of waste Particle Board and polyproplylene over nanoporous Al-MCM-41 catalysts.
Journal of Nanoscience and Nanotechnology, 2014Co-Authors: Hyung Won Lee, Sunghoon Park, Jong-ki Jeon, Suek Joo Choi, Youngkwon ParkAbstract:Catalytic co-pyrolysis of Particle Board, a waste wood biomass, and polypropylene (PP), a petroleum-based plastic, was carried out with a mixing ratio of 1:1 over a representative mesoporous material, Al-MCM-41 catalyst. The Si/Al ratios of the Al-MCM-41 catalysts were controlled at 20 and 80 to investigate the effect of the acidity of the catalyst. The characterization of the catalyst was performed by X-ray diffraction, N2 adsorption-desorption, and NH3 temperature-programmed desorption. The catalytic pyrolysis of the Particle Board showed a higher yield of gas and lower yield of oil than the non-catalytic pyrolysis. In oil, the concentration of levoglucosan decreased, and those of furans, furanones, cyclopentanones, aromatics, and light phenolics increased. In the case of the co-pyrolysis of the Particle Board and PP, C10-C17 products corresponding to the diesel range greatly increased and resulted in an improvement of the bio-oil quality. This suggests that PP is decomposed on the acidic sites of the Al-MCM-41 catalyst, resulting in an increased production of hydrocarbons in the range of diesel.

catalytic conversion of Particle Board over microporous catalysts
Renewable Energy, 2013Co-Authors: Suek Joo Choi, Jong-ki Jeon, Sunghoon Park, In Gu Lee, Changkook Ryu, Dong Jin Suh, Youngkwon ParkAbstract:Catalytic pyrolysis of Particle Board, a type of waste wood that is increasingly produced all over the world, was carried out over three types of zeolite catalysts: HBETA, HZSM-5, and Ga-impregnated HZSM-5 (Ga/HZSM-5). Experiments conducted using a batch reactor showed that the bio-oil yield and gas yield in catalytic pyrolysis were lower and higher than those in non-catalytic pyrolysis, respectively. Analysis of the bio-oil using pyrolysis gas chromatography/mass spectrometry (Py-GC/MS) showed that the yields of high-value-added species such as aromatics and phenolics were increased to a large extent by catalytic upgrading, thus increasing the value of the product bio-oil. In particular, HZSM-5 exhibited high selectivity for aromatic compounds, and impregnation of Ga further increased the selectivity. HBETA could cause levoglucosans to decompose completely owing to its large pore size, resulting in increased yields of low-molecular-mass species.

Catalytic conversion of waste Particle Board to bio-oil using nanoporous catalyst.
Journal of Nanoscience and Nanotechnology, 2012Co-Authors: Youngkwon Park, Jong-ki Jeon, Sunghoon Park, Suek Joo Choi, Ryong Ryoo, Jeongnam Kim, Kwang-eun JeongAbstract:UNLABELLED The catalytic pyrolysis of waste wood including the Particle Board was examined by pyrolysis gas chromatography/mass spectrometry (Py-GC/MS) to produce bio-oil. Three different catalysts with a nanoporous structure, Al-MCM-48, Meso-MFI, and Pt-Meso-MFI, were used and their performances were compared. When MCM-48 was used, the quality of the bio-oil product was better than that prepared by non-catalytic pyrolysis but the improvement was limited due to its weak acid sites. On the other hand, Meso-MFI, which has both an MFI structure and strong acid sites, exhibited much better cracking ability and higher selectivity for aromatics. Moreover, Pt-impregnation on Meso-MFI resulted in an even higher selectivity for aromatics and phenolics, which are important raw materials in various petroleum chemical processes.
