... due to the catalytic influence of AAEM on the Boudouard reaction, while the acid-washed biomass yielded the lowest syngas yield. During gasification, the syngas yield, energy yield, and overall energy efficiency were enhanced by 83.4 (by wt%), 44.6 (by wt%), and 44.6%, respectively, using alkali...

... during gasification at 1223 K that provided only ash residue. The CO 2 gasification of cigarette butts provided an effective pathway to utilize 0.5 g CO 2 /g feedstock at 1223 K to form valuable CO by the Boudouard reaction. Compared with the gasification of other solid wastes, syngas energy yield from...
