liquid and gaseous fuel from waste plastics by sequential pyrolysis and Catalytic Reforming processes over indonesian natural zeolite catalysts
Waste Technology, 2014Co-Authors: Mochamad Syamsiro, Harwin Saptoadi, Shuo Cheng, Wu Hu, Nosal Nugroho Pratama, Wega Trisunaryanti, Kunio YoshikawaAbstract:In this study, the performance of several differently treated natural zeolites in a sequential pyrolysis and Catalytic Reforming of plastic materials i.e. polypropylene (PP) and polystyrene (PS) were investigated. The experiments were carried out on two stage reactor using semi-batch system. The samples were degraded at 500°C in the pyrolysis reactor and then reformed at 450°C in the Catalytic reformer. The results show that the mordenite-type natural zeolites could be used as efficient catalysts for the conversion of PP and PS into liquid and gaseous fuel. The treatment of natural zeolites in HCl solution showed an increase of the surface area and the Si/Al ratio while nickel impregnation increased the activity of catalyst. As a result, liquid product was reduced while gaseous product was increased. For PP, the fraction of gasoline (C 5 -C 12 ) increased in the presence of catalysts. Natural zeolite catalysts could also be used to decrease the heavy oil fraction (>C 20 ). The gaseous products were found that propene was dominated in all conditions. For PS, propane and propene were the main components of gases in the presence of nickel impregnated natural zeolite catalyst. Propene was dominated in pyrolysis over natural zeolite catalyst. The high quality of gaseous product can be used as a fuel either for driving gas engines or for dual-fuel diesel engine.

Fuel oil production from municipal plastic wastes in sequential pyrolysis and Catalytic Reforming reactors
Energy Procedia, 2014Co-Authors: Mochamad Syamsiro, Tinton Norsujianto, Putri Noviasri, Zainal Alimuddin, Harwin Saptoadi, Shuo Cheng, Kunio YoshikawaAbstract:The aim of this research was to study fuel oil production from municipal plastic wastes by sequential pyrolysis and Catalytic Reforming processes. Three kinds of municipal plastic wastes were collected from the final disposal site and the small recycling company in Yogyakarta city, Indonesia. Commercial Y-zeolite and natural zeolite catalysts were used in this study. The results show that the feedstock types strongly affect the product yields and the quality of liquid and solid products. HDPE waste produced the highest liquid fraction. The catalyst presences reduced the liquid fraction and increased the gaseous fraction. Furthermore, municipal plastic wastes pyrolysis produced higher heating value solid products than those of biomass and low rank coal. © 2014 The Authors. Published by Elsevier Ltd.

Thermo-Catalytic Reforming of spent coffee grounds
Bioresources and Bioprocessing, 2019Co-Authors: Mohamed Elmously, Andreas Apfelbacher, Robert Daschner, Nils Jäger, Andreas HornungAbstract:Conversion of spent coffee grounds through the Thermo-Catalytic Reforming system (TCR^®) is evaluated in this study. While, the TCR^® is a technology that has been developed by Fraunhofer UMSICHT, which combines an intermediate pyrolysis and a Catalytic Reforming. The temperature of the Catalytic reformer is varied between 500 and 700 °C to achieve an optimum yield quantities and qualities of the products. The hydrogen concentration is maximized at a Reforming temperature of 700 °C, and a gas yield up to 52 wt% is achieved. The thermal stable bio-oil produced at 700 °C has the highest calorific value of 36.8 MJ/kg with significantly low oxygen and water content, low viscosity and low TAN (total acid number). Furthermore, the maximum bio-oil and char yields are obtained at the lowest Reforming temperature of 500 °C. Overall spent coffee grounds show a great potential as feedstock in the Thermo-Catalytic Reforming for energy and bio-chemicals production.

Thermo-Catalytic Reforming of municipal solid waste
Waste Management, 2017Co-Authors: Miloud Ouadi, Nils Jaeger, Charles Greenhalf, Joao Santos, Roberto Conti, Andreas HornungAbstract:Abstract Municipal Solid Waste (MSW) refers to a heterogeneous mixture composed of plastics, paper, metal, food and other miscellaneous items. Local authorities commonly dispose of this waste by either landfill or incineration which are both unsustainable practices. Disposing of organic wastes via these routes is also becoming increasingly expensive due to rising landfill taxes and transport costs. The Thermo-Catalytic Reforming (TCR®) process, is a proposed valorisation route to transform organic wastes and residues, such as MSW, into sustainable energy vectors including (H 2 rich synthesis gas, liquid bio-oil and solid char). The aim herein, was to investigate the conversion of the organic fraction of MSW into fuels and chemicals utilising the TCR technology in a 2 kg/h continuous pilot scale reactor. Findings show that MSW was successfully processed with the TCR after carrying out a feedstock pre-treatment step. Approximately, 25 wt.% of the feedstock was converted into phase separated liquids, composed of 19 wt.% aqueous phase and 6 wt.% organic phase bio-oil. The analysis of the bio-oil fraction revealed physical and chemical fuel properties, higher heating value (HHV) of 38 MJ/kg, oxygen content 2 content of 36 vol% and HHV of 17.23 MJ/Nm 3 , and 31 wt.% char with a HHV of 17 MJ/kg. The production of high quantities of H 2 gas and highly de-oxygenated organic liquids makes downstream hydrogen separation and subsequent hydro-deoxygenation of the produced bio-oil a promising upgrading step to achieve drop-in transportation fuels from MSW.

Thermo-Catalytic Reforming of Woody Biomass
Energy & Fuels, 2016Co-Authors: N. Jäger, Andreas Apfelbacher, Robert Daschner, Samir Binder, J Neumann, Roberto Conti, Andreas HornungAbstract:The objective of the present work is to determine the potentials of woody residues from agriculture (tree trimmings or vine shoots) for fuel applications. Fraunhofer UMSICHT is carrying out research for a new thermochemical conversion technology to convert biogenic residues into valuable storable products, such as carbonizates, hydrogen, and fuel. Thermo-Catalytic Reforming (TCR) is an intermediate pyrolysis combined with a unique integrated Catalytic Reforming step. In this experimental study, the TCR of three different woody biomasses has been investigated in a 2 kg/h laboratory-scale plant. The feedstocks were woody residues produced from the pruning of agricultural lands. This is a sustainable biomass solution with an up-to-date great unexploited potential. The results revealed that the composition of the feedstock had only a minor effect in the compositions and characterizations of the products, with the Catalytic Reforming step at 973 K. The gas had a higher heating value between 14.6 and 14.9 MJ/kg...

production and characterization of a new quality pyrolysis oil char and syngas from digestate introducing the thermo Catalytic Reforming process
Journal of Analytical and Applied Pyrolysis, 2015Co-Authors: J Neumann, Andreas Apfelbacher, Samir Binder, James R Gasson, Paula Ramirez Garcia, Andreas HornungAbstract:Abstract A 2 kg/h laboratory scale thermo-Catalytic Reforming (TCR ® ) unit was designed and commissioned at Fraunhofer UMSICHT to convert digestate into enhanced pyrolysis products. The TCR ® reactor is an intermediate pyrolysis screw reactor connected to a reformer. In the experimental series reported, digestate pellets were used as feedstock. The aim herein was to test and characterize the TCR ® reactor for the feedstock digestate and its products for syngas applications and decentralized power production. Prior to the pyrolysis experiments thermal gravimetric analysis was used to analyze the weight loss over temperature. The digestate was pyrolyzed at a constant temperature of 400 °C, whereas the reformer temperature was varied between 500 and 750 °C. Following the cooling and condensation of pyrolysis vapors, these separated into bio-oil, an aqueous phase and permanent gases. Hydrogen concentration increased together with increased Reforming temperatures and reached a maximum of 35 vol% at 750 °C. The bio-oil generated at 750 °C had a higher heating value of 33.9 MJ/kg, 1.7 wt% water content and a total acid number of 4.9 mg KOH/g. It was possible to convert over 91% of the energy content of the biomass into usable products. These results are analyzed together with the extensive feedstock and product characterization and the experimental parameters and discussed.
