摘要
In the hydrodesulfurization reaction zone operated under mild conditions to remove unstable organic sulfur compounds, desulfurization of the hydrocarbon feedstock is first achieved by contacting the hydrodesulfurization catalyst with the entire feedstock. . To obtain two hydrocarbon fuel fractions, the flushing column downstream of the hydrodesulfurization reaction zone fractionates the effluent at the target cut point temperature. The first fraction boiling at or above the target cut point temperature contains residual refractory organosulfur compounds. Since the organosulfur compounds boiling in this fraction range were unstable organosulfur compounds that were first removed by mild hydrodesulfurization, the second fraction boiling below the target cut-point temperature is essentially Organic sulfur compounds are not included. Contacting the first fraction with a gaseous oxidant over an oxidation catalyst having the formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert refractory organic sulfur compounds to SOx and low sulfur hydrocarbons Let Byproduct SOx is then removed to produce a stream containing reduced levels of organosulfur compounds.
