The HDS process involves the catalytic reaction of sulfur-containing compounds with hydrogen gas (H2) to produce hydrogen sulfide (H2S) and desulfurized hydrocarbons. The general reaction can be represented as:
R-S + H2 → R-H + H2S
Here, R-S represents a sulfur-containing organic molecule, and R-H is the desulfurized hydrocarbon. The reaction typically occurs in a fixed-bed reactor packed with a solid catalyst under high temperature and pressure conditions.
