研究了合成低碳混合醇钼系耐硫催化剂的制备方法和CO加H_2反应性能。考察了K_2CO_3作为助剂对提高醇的选择性的作用。用XRD、TEM及XPS等多种测试手段分析了K~+的结构状态,发现在催化剂表面上生成了微晶活性相。
The preparation method and CO + H 2 reactivity of the low-carbon mixed molybdenum-based sulfur-tolerant catalyst were studied. The effect of K 2 CO 3 as a promoter on the selectivity of alcohol was investigated. The structure of K ~ + was analyzed by XRD, TEM and XPS. It was found that the microcrystalline active phase was formed on the catalyst surface.
