The influence of the catalyst and reactor temperature on yield and product composition was studied at the temperature range of 700oC - 900oC. Over the ranges of experimental conditions examined, calcined dolomite revealed better catalytic performance, at the presence of steam, tar was completely decomposed as temperature increases from 800oC to 900oC. Higher temperature resulted in more H2 and CO2 production, and dry gas yield. The highest H2 content of 51.02 mol%, and the highest H2 yield of 1.66 m3/kg biomass were observed at the highest temperature level of 900oC.展开更多

The influence of the reactor temperature on yield and product composition was studied at the temperature range of 700 PoPC-900 PoPC. Over the ranges of experimental con-ditions examined, tar was completely decomposed as temperature increases from 800P oPC to 900 PoPC. Higher temperature resulted in more HR2R and COR2R production, and dry gas yield. The highest H2 content of 51.02 V%, and the highest HR2 Ryield of 1.66 mP3P/kg biomass were observed at the highest temperature level of 900P oPC.展开更多
