本文考察不同制备方法和制备程序制得之MoS_x-K~+/SiO_2催化剂对合成气转化为低碳混合醇的催化性能,探讨不同助剂(包括K_2CO_3,KF,KCl等)对催化剂活性和选择性的影响,首次报道以K_2MoS_4作为前驱物料制得的MoS_x-K~+/SiO_2催化剂具有与(NH_4)_2MoS_4-K_2CO_3/SiO_2衍生得到的催化剂几乎一样高的催化活性和选择性,其结果为具有实用意义的催化剂的研制提供依据。
In this paper, we investigated the catalytic performance of MoS_x-K ~ + / SiO_2 catalysts prepared by different preparation methods and preparation procedures for the conversion of syngas to low-carbon mixed alcohols. The effects of different additives (including K_2CO_3, KF and KCl) on the catalyst activity and selectivity It is reported for the first time that the catalyst MoS_x-K ~ + / SiO_2 with K_2MoS_4 as the precursor has almost the same catalytic activity and selectivity as the catalyst derived from (NH_4) _2MoS_4-K_2CO_3 / SiO_2. Practical significance of the catalyst to provide the basis for the development.
