Co-Pyrolysis of Municipal Solid Waste (Msw) and Biomass with Co/Sludge Fly Ash Catalyst

Catalytic co-pyrolysis of municipal solid waste (MSW) and biomass pine sawdust (PSD) under sludge fly ash (SFA) could be a breakthrough towards the energy challenges and waste management. This paper aims to develop a unique cobalt-alkali-SFA (Co-A-SFA) catalyst, in order to investigate its influence under optimal operating conditions in a fixed bed reactor for syngas production. The catalytic activity was assessed under different Co loading and support ratios. The results indicated that in the presence of Co-A-SFA catalyst, gas production increased due to alkali pretreated fly ash catalyst. Moreover, increasing the Co loading from 5wt.% to 10wt.%, the syngas production increased irrespective of the individual feedstock ratios. Catalytic co-pyrolysis of MSW and PSD also minimized the concentration of complex liquid compounds and heavy hydrocarbons. Therefore, this study establishes a new approach towards energy production and waste management through useful resource utilization of MSW, PSD and SFA. The outcomes acquired in this investigation showed that blended feedstock in co-pyrolysis of MSW and pine sawdust could enhance production of valuable syngas under SFA-based catalyst
