烟气脱硫石膏%催化还原%Fe-Ni复合催化剂%硫化钙
煙氣脫硫石膏%催化還原%Fe-Ni複閤催化劑%硫化鈣
연기탈류석고%최화환원%Fe-Ni복합최화제%류화개
采用Fe-Ni复合催化剂，在温度650℃条件下即可将烟气脱硫石膏催化还原为硫化钙，还原率达95%以上。研究了反应温度、催化剂加入量及还原气体含量等因素对还原反应的影响。
採用Fe-Ni複閤催化劑，在溫度650℃條件下即可將煙氣脫硫石膏催化還原為硫化鈣，還原率達95%以上。研究瞭反應溫度、催化劑加入量及還原氣體含量等因素對還原反應的影響。
채용Fe-Ni복합최화제，재온도650℃조건하즉가장연기탈류석고최화환원위류화개，환원솔체95%이상。연구료반응온도、최화제가입량급환원기체함량등인소대환원반응적영향。
The catalytic reduction of flue gas desulfurization (FGD) gypsum to calcium sulfide over Ni-Fe composite catalyst was investigated.An optimum conversion rate of more than 95% was obtained at 650℃.The effect of parameters such as temperature,input of catalyst,and reduction gas CO concentration on the reduction reaction was studied.
