Dimethyl Sulfide also known as DMS is a presulfiding agent for steam cracking which turns hydrocarbons into ethylene and propylene used for olefin-based products
DMS is used to reduce coke and carbon monoxide formation during high temperature thermal cracking of hydrocarbons in the tubular reactors
