Hüdrodesulfuriseerimise
Hüdrodesulfuriseerimine, often abbreviated as HDS, is a catalytic chemical process used in petroleum refining to remove sulfur compounds from hydrocarbons. This is a crucial step in producing cleaner fuels like gasoline, diesel, and jet fuel, which have stricter environmental regulations regarding their sulfur content. The primary goal of HDS is to convert sulfur-containing molecules into hydrogen sulfide (H2S), which can then be more easily separated and treated.
The process typically involves reacting the sulfur-containing feedstock with hydrogen gas at elevated temperatures and pressures
HDS is a cornerstone of modern refining, significantly reducing the release of sulfur dioxide (SO2) into the
