Thiochemical Overview

Thiochemicals play a crucial role in catalyst sulfiding and steam cracker tube passivation. At Reactor Resources, we provide a range of high-quality sulfur chemicals to meet your needs.

Dimethyl Disulfide (DMDS)

Dimethyl Disulfide (DMDS) is the go-to thiochemical for activating hydrotreating and hydrocracking catalysts, also known as pre-sulfiding. Hydrotreating catalysts contain metal oxides that must be converted into active metal sulfide before use. The injection of DMDS begins once the reactor reaches the optimal temperature, rapidly decomposing and generating H2S, which is essential for converting metallic oxides into catalytic sulfides. Explore the advantages of DMDS sulfiding through our comprehensive guide. Learn More>>

Dimethyl Sulfide (DMS)

Dimethyl Sulfide (DMS) is continuously injected into the furnace section of a steam cracker to prevent coke formation and ensure control over CO formation during the entire process. We offer highly pure DMS with minimal carbon disulfide (CS2) content, ensuring top-quality performance. Learn more about the countless benefits of incorporating DMS into your steam cracker.

Tertiary Butyl Polysulfide (TBPS)

As another sulfiding agent supplied by Reactor Resources, Tertiary Butyl Polysulfide (TBPS) can effectively activate hydrotreating and hydrocracking catalysts. While TBPS contains less sulfur than DMDS, it still offers distinct advantages for in-situ sulfiding. Discover how TBPS can elevate your sulfiding processes by delving into our comprehensive information. Learn More>>
