摘　　要：对在以铁为主要活性组分的催化剂上进行CO_2+H_2合成低碳烯烃的研究。通过对载体、金属担载量、助剂和反应条件的考察结果表明,Fe/AC催化剂有较好的性能。在合适的反应条件下Fe/AC催化剂生成C_2~=～C_4~=有较高的选择性。结合TPR和Mossbauer谱技术考察了催化剂的活性相生成过程。The conversion of carbon dioxide and hydrogen to light olefins in one step over iron catalyst has been studied.From the research for the carrier and promoter, the amount of Fe loaded and reaction condition, it has been found that the Fe/AC catalyst has excellent activity and good selectivity.The selectivity to light olefins is very high under the matching catalystic reaction condition.The causes for activation of catalysts has also been investigated by TPR and Mossbauer spectroscopy techniques.
