摘要: The cracking of model tar species from municipal solid waste gasification using dried sewage sludge char (DSS char) and bottom ash catalyst (BAC) was investigated, the catalytic performance compared to that well-studied calcined dolomite, NiO/γ-Al2O3, non-catalytic thermal cracking. effects temperature, internal structure, chemical composition, functional groups on were characterized. results showed that, when toluene selected as species, conversion ratios for all catalysts over 94% at 950 °C. efficiency ordered NiO/γ-Al2O3 > dolomite DSS BAC When temperature increased 750 850 °C, 68.8 40.1% 81.5 63.2%, respectively. H2 coke major products cracking, promoted yield hydrogen. lower heating value product gas followed same rul...
