以堇青石为载体,采用浸渍法制备了表面多孔的堇青石负载Fe-Mo催化剂,并利用SEM、FT-IR、XRD、EDX、XPS等对催化剂的结构和形貌进行表征。研究表明,用在450℃氩气气氛下焙烧所制备的Fe-Mo催化剂催化合成乙烯的效果最明显。此外,在常压条件下,研究了不同温度、空速、合成气比例对合成乙烯的影响,结果表明,在450℃、H2/CO为2、反应空速为2.0L/g cat·h时,CO转化率达到63.5%,乙烯的选择性达到46.3%。Fe-Mo催化剂对合成气合成乙烯具有高转化效率,可望为工业生产乙烯提供新的参考与依据。 The porous cordierite supported Fe-Mo catalyst was prepared by impregnation method using cordierite as carrier. The structure and morphology of the catalyst were characterized by SEM, FT-IR, XRD, EDX and XPS. The results show that the most obvious effect of catalytic synthesis of ethylene with the Fe-Mo catalyst prepared by calcination at 450 ℃ under argon atmosphere. In addition, the effects of different temperature, space velocity and syngas ratio on the synthesis of ethylene were studied under normal pressure. The results showed that at 450 ℃, H2 / CO was 2 and the reaction space velocity was 2.0 L / g cat · h , CO conversion reached 63.5% and ethylene selectivity reached 46.3%. Fe-Mo catalyst for the synthesis of ethylene synthesis with high conversion efficiency, is expected to provide a new industrial ethylene reference and basis.
