Abstract: Based on the domestic and foreign literature on the synthesis of butyl mercaptan using hydro-gen sulfide as a sulfur source,the characteristics of various methods were discussed,especially the olefinvulcanization method. The catalytic behaviors of Lewis acid catalysts,zeolite catalysts,ion exchangeresin catalysts,and transition metal salt-modified aluminum-based catalysts were expounded. The anal-ysis suggests that the transition metal salt-modified aluminum-based catalyst can stabilize the activephase in the metastable state and has high catalytic activity,because of the strong interaction betweenthe carrier and active metal. In order to remove hydrogen sulfide and obtain economic benefits,the sul-fur source can be hydrogen sulfide in reducing flue gas and the carbon source can be low-carbon olefinsproduced in the process of petroleum catalytic cracking and olefins preparation from methanol.
