Influence of Catalyst and Temperature on Gasification Performance by Externally Heated Gasifier

In the present study the catalytic steam gasification of biomass to produce hydrogen-rich gas with calcined dolomite and Nano-NiO/γ-Al2O3 as catalyst in an externally heated fixed bed reactor was investigated. 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.
