Hydrodesulfurization | FSC 432: Petroleum Refining

Hydrodesulfurization. Desulfurization of fuels is commonly achieved by catalytic hydrodesulfurization (HDS), in which the organic sulfur species are converted to H 2 S and the corresponding hydrocarbon, as in the following reaction: R-SH + H 2 → R-H + H 2 S. Here R represents an alkyl group, such as methyl (CH 3 –), or ethyl (C 2 H 5 –). Figure 9.2 shows the type and relative reactivity ...
