The KT201 type hydroconversion catalyst uses Co-Mo as its active components, and is currently the catalyst with the longest service life (more than ten years) and a wide range of applications. It has a high conversion capacity for complex organic sulfides. It can be used for the hydrogenation conversion of natural gas, oil field gas, liquefied petroleum gas, naphtha and other gases, organic sulfide in benzene hydrocarbons, and olefin hydrogenation and oxygen hydrogenation. It is suitable for petrochemical enterprises such as large and medium-sized ammonia plants, methanol plants, and hydrogen production. The catalyst can reduce the organic sulfur content in raw hydrocarbons to below 0.1 ppm.
