摘　　要：利用生物柴油副产物甘油和CO_(2)干重整制取高附加值合成气,关键是高性能催化剂的选择和研究。通过胶体溶液燃烧法制备了CoFe/CeO_(2)催化剂,在固定床反应器中,温度范围650~800℃条件下,研究了CO_(2)与甘油干重整过程中的催化活性和稳定性。结果表明,胶体溶液燃烧法制备的CoFe/CeO_(2)催化剂具有典型的介孔结构,比表面积为33.4~40.8 m^(2)/g,表现出了活性组分Co-Fe与载体CeO_(2)较强的相互作用。7CoFeCe显示出了较好的干重整催化性能,750℃下甘油转化率达84.8%,CO_(2)转化率达19.9%。随着温度的升高,CO_(2)转化率提高,在800℃下,CO_(2)转化率达到了30.3%,表明高温有利于逆水汽变换反应。稳定性实验表明,介孔CoFe/CeO_(2)催化剂具有较好的干重整稳定性。The selection and research of high performance catalyst is the key to producing high value-added syngas from biodiesel by-product glycerol and CO_(2)dry reforming.CoFe/CeO_(2)catalyst was prepared by colloidal solution combustion method,and the catalytic activity and stability of dry reforming of CO_(2)and glycerol were studied in a fixed-bed reactor at a temperature range of 650~800℃.The results showed that the CoFe/CeO_(2)catalyst prepared by the colloidal solution combustion method had a typical mesoporous structure with a specific surface area of 33.4~40.8 m^(2)/g,showing a strong interaction between the active component Co-Fe and the support CeO_(2).7CoFeCe showed good catalytic performance for dry reforming.The conversion of glycerol at 750℃was 84.8%,and the CO_(2)conversion was 19.9%.The CO_(2)conversion increased with the increase in temperature,and the maximum conversion of CO_(2)at 800℃was 30.3%.It showed that the high temperature was conducive to the reverse water gas shift reaction.The stability experiment showed that the mesoporous CoFe/CeO_(2)catalyst had good dry reforming stability.
