thermodynamic evaluation of portuguese Municipal Solid Waste gasification
Journal of Cleaner Production, 2016Co-Authors: Nuno Couto, Valter Silva, Abel RouboaAbstract:Abstract Through a massive population growth, Waste management has become one of the main concerns of our time. In Portugal the growing volume of Municipal Solid Waste has become a central problem for Municipalities, due to lack of space and the high costs to solve it. Gasification has received a renewed interest in the Municipal Solid Waste treatment since it limits dioxins formation, presents higher efficiency and requires less expensive gas cleaning equipment when compared to available methods gas. However, to make to process more appealing to both private sector and government institutions is necessary to overcome some concerns related to the process. To expedite the mainstream of this technology a first and second law analysis conducted on Portuguese Municipal Solid Waste was carried out. The thermodynamic method was coupled with a previously developed numerical model. Said model was validated using data from a pilot scale plant. Both energy and exergy values were investigated in order to evaluate Portuguese Municipal Solid Waste as an energy source. Optimal operating point was found at 900 °C for an equivalent ratio of 0.25. Tar content energy values decreased as high as 80% when temperature was increased to 900 °C. A comparison between several gasification efficiencies was investigated.

Progress in catalytic pyrolysis of Municipal Solid Waste
Energy Conversion and Management, 2020Co-Authors: Ali Faramarzi, Shu Zhang, Yi Wang, Mortaza GholizadehAbstract:Abstract Municipal Solid Wastes occupy lands and create environmental issues, which has stimulated interest from governments to research community for converting them into useful products such as fuels, chemicals and electricity through the thermochemical methods including pyrolysis, gasification, etc. Pyrolysis converts Municipal Solid Wastes into fuels in gaseous, liquid and Solid form. Owing to the unsatisfactory quality of fuels from non-catalytic pyrolysis, catalytic pyrolysis was proposed to improve especially the properties of liquid fuel in the presence of catalyst. Catalyst is thus an essential parameter in catalytic pyrolysis, as the specifications of catalysts could show profound influence on composition of the liquid fuel. Specifically, the formulation of catalyst, the exposed surface species, the acidic sites, the porous structures, etc all affect catalytic performances in pyrolysis of Municipal Solid Waste. Up to now, there have been a number of catalysts developed for catalytic pyrolysis of the mixture of Municipal Solid Waste. These catalysts, depending on their specifications, show the distinct catalytic performances in catalytic pyrolysis of Municipal Solid Waste and also varied lifetime span in the pyrolysis, etc. The feasibility of the catalysts in especially the application in industrial scale needs further evaluation and verification. This review dedicates to the progress of the development of the catalysts for catalytic pyrolysis of mixed Municipal Solid Waste. The advantages and disadvantages of each types of catalysts are discussed and compared. Suggestions were given for the future stages of developments of catalyst for the small to large-scale operation of catalytic pyrolysis of Municipal Solid Waste. The results of techno-economic review showed that catalyst could reduce the amount of emission and produce more valuable products. However, the cost of regeneration might increase the cost of operation significantly.

Biochar from Municipal Solid Waste for resource recovery and pollution remediation
Environmental Chemistry Letters, 2019Co-Authors: Viraj Gunarathne, Ahamed Ashiq, Sammani Ramanayaka, Prabuddhi Wijekoon, Meththika VithanageAbstract:Open dumping of Municipal Solid Waste is a common method of Waste disposal in developing countries, thus leading to pollution by gaseous emissions and landfill leachate discharge. Biochar, a carbonaceous material produced from any biomass, is a means to transform Municipal Solid Waste into a value-added product, which can be used for resources recovery and for contaminant mitigation. This review presents the production of biochar from Municipal Solid Waste. Biochar from Municipal Solid Waste has various properties depending on the production technology. We describe the use of biochar as a green adsorbent for leachate treatment and as a permeable reactive barrier material to reduce contamination. Furthermore, biochar can be used as a cover material to reduce odors.
