Catalyst for synthesizing methyl mercaptan from hydrogen sulfide and methanol and preparation method of catalyst

The invention provides a catalyst for synthesizing methyl mercaptan from hydrogen sulfide and methanol, the catalyst comprises a carrier and an active component, the carrier in the catalyst comprises 0.1-5 wt% of alkaline earth metal oxide, 0.1-2.5 wt% of titanium dioxide, and the balance of pseudo-boehmite; the active component comprises 5-30 wt% of a soluble tungsten-containing compound, the molar ratio of organic acid potassium salt to the soluble tungsten-containing compound is (0.1-5): 1, and the molar ratio of methyl cellulose is 0.1-1 wt%. The catalyst disclosed by the invention is relatively high in methanol conversion rate, methyl mercaptan selectivity and methyl mercaptan yield, and the service life of the catalyst is greatly prolonged. 本发明提供一种用于硫化氢与甲醇合成甲硫醇的催化剂，所述催化剂包括载体及活性组分，所述催化剂中载体包括碱土金属氧化物wt0.1～5％、二氧化钛wt0.1％～2.5％，余下部分为拟薄水铝石；所述活性组分包括可溶性含钨化合物wt5％～30％、有机酸钾盐与可溶性含钨化合物的摩尔比为(0.1～5):1、甲基纤维素wt0.1％～1％。本发明催化剂甲醇转化率、甲硫醇选择性、甲硫醇得率均较高，且催化剂的寿命大幅提升。
