新型催化剂改进二氧化碳转化为合成气
第4期新型催化剂改进二氧化碳转化为合成气
美国伊利诺伊大学芝加哥分校（UIC ）的研究人已确定二硫化钼为一种很有前途、具有成本效益的用于电化学还原二氧化碳的贵金属催化剂的替代品。UIC 的Amin S K 教授及
其同事开发了一种新型的使用二硫化钼和离子液体的二氧化碳还原两步催化工艺,新型催化剂可将二氧化碳直接转化为合成气，而无需昂贵的二次气化过程，提高了效率、降低了成本。合成气中一氧化碳与氢气的比例也可以很容易地进行调控。

Abstract:The catalysts of x%Fe 2O 3/KX,y%CoO/KX and z%NiO/KX were prepared by ion exchanging and impregnating method,and characterized by ICP 鄄AES,Py 鄄IR and TPD methods.Their catalytic behaviors for side chain alkylation of toluene with methanol were investigated.For x%Fe 2O 3/KX,when the amount of Fe 2O 3supported on KX increased,the conversion of methanol increased,the yield of ethylbenzene increased first and then decreased,and the yield of styrene decreased.For y%CoO/KX,when the amount of CoO supported on KX increased,the conversion of methanol increased rapidly,the yield of ethylbenzene increased first and then decreased,and the yield of styrene decreased rapidly.For z%NiO/KX,when the amount of NiO supported on KX increased,the conversion of methanol decreased slightly,the yields of ethylbenzene and styrene decreased rapidly,and the yield of xylene increased significantly.
