摘要
Abstract
The straw straw gasification was conducted in fixed bed gasifier using straw as raw material, steam as gasification agent and dolomite as catalyst. The effects of the particle size (5-20 mm), bed height (550-1 000 mm) and the calcination of dolomite on the gasification were studied. The results demonstrated that the decrease of particle size, increase of bed height and dosage of dolomite could improve the volume fraction of hydrogen in the produced gases. When the dolomite particle size was 5-10 mm, the dolomite bed height was 1 000 mm and the calcined dolomite content was 100%, the maximal volume fraction of hydrogen could reach 53.18%, the maximal hydrogen yield was 0. 92 m3/kg, and the maximal fuel gas yield was 1. 72 m3/kg. In addition, the maximal gasification efficiency could be as high as 99.93% and the maximal steam decomposition efficiency was 51.28%.关键词
