Production of hydrocarbons low in sulfur and mercaptans comprises two-stage catalyzed hydrodesulfurization with intermediate separation of hydrogen sulfide, for obtaining ultra-low sulfur petrol fuels

摘要

Desulfurization involves catalytic hydrodesulfurization giving a 90% rate of desulfurization, the separation of most of the hydrogen sulfide from the effluent, and a second hydrodesulfurization in conditions giving a degree of desulfuration lower than the primary stage. An Independent claim is also included for the applications of the process.
