Catalytic gasification of pine sawdust for producing hydrogen-rich gas
摘要
Abstract
Steam catalytic gasification experiments of pine sawdust to produce hydrogen-rich gas were carried out in a high-temperature fixed bed reactor with Ni-CaO as the catalyst. The influence of catalyst dosage,gasification temperature and steam flow rate on hydrogen content were investigated. The results showed that by increasing the catalyst to sawdust ratio from 0 to 1.5(g/g),the hydrogen content was increased from 45.58% to 60.23%,and the hydrogen yield was increased from 38.80 g/kg to 93.75g/kg,whereas the hydrogen content and hydrogen yield only showed a modest increase when the ratio was changed into 2. Increasing the gasification temperature from 700℃ to 750℃ significantly increased the hydrogen content from 54.24% to 60.23%,and decreased the carbon dioxide content from 21.09% to 13.18%,but higher temperature gave rise to a decrease in the hydrogen content and the low heating value.When the best gasification temperature was taken as 750℃,and the catalyst to sawdust ratio and the steam flow rate were 1.5(g/g) and 0.34g/(min·g),the resulting hydrogen content,dry gas yield and low heating value were 60.23%,93.75g/kg,and 12.13MJ/m3,respectively.关键词
