摘　　要：介绍了五种甲硫醇的生产工艺用催化剂,尤其是硫化氢甲醇法、甲醇二硫化碳法和高硫合成气法用催化剂的制备工艺和性能。分析了添加不同的助剂对催化剂的性能的改善。三种工艺路线生产甲硫醇催化剂中主体活性组分都是ⅥB族过渡金属元素W和Mo,常用的助催化剂为K,载体为具有一定孔特性的二氧化硅和氧化铝。<Abstrcat> Preparation methods and properties of the catalysts for five methanthiol synthesis processes were reviewed, particularly those for high H_2S syngas system,CH_3OH-H_2S system and CH_3OH-CS_2 system. Influences of promoters on improvement of the catalytic properties were discussed. For the catalysts used in above-mentioned three systems , the main active components are ⅥB transition metal W and Mo, with K as the promoter and silica and alumina as the carriers.
