抄録

The uptake behavior of hydrogen sulfide was observed for a rapid pyrolysis char in a H2S/N2 gas stream. More than 13 wt% was obtained for sulfur content in the char contacted with H2S/N2 mixture at 1073 K. Chemical analysis indicated that the increment of sulfur attained was organic sulfur solely in solid phase. Gasification was conducted in a carbon dioxide stream at 1073 K for the char which had trapped hydrogen sulfide. The extent of sulfur reduction in the solid phase was smaller than the weight loss of char during gasification to the extent of 44-55%.
