  • Process for hydrodesulphurizing an olefinic gasoline
    Patent number: 10377956
    Abstract: A process for the treatment of a gasoline containing sulphur-containing compounds, olefins and diolefins: a) fractionating the gasoline into at least: a light gasoline cut LCN; a primary intermediate gasoline cut, MCN; and a primary heavy gasoline cut HHCN; b) desulphurizing the primary intermediate gasoline cut MCN alone producing an at least partially desulphurized primary intermediate gasoline cut MCN; c) desulphurizing the primary heavy gasoline cut HHCN alone producing an at least partially desulphurized primary heavy gasoline cut HHCN; d) sending, as a mixture, the partially desulphurized primary intermediate gasoline cut MCN and the partially desulphurized primary heavy gasoline cut HHCN to a separation column separating a gaseous stream containing hydrogen and H2S, a secondary intermediate gasoline cut MCN with low sulphur and mercaptans contents and a secondary heavy gasoline cut HHCN containing sulphur-containing compounds including recombinant mercaptans; e) desulphurizing the secondary heavy g
