Abstract
A catalytic reforming process for producing gasoline of reduced benzene content includes the steps of reforming a reformer feedstock that includes a naphtha stream to produce a gasoline reformate product stream; splitting the gasoline reformate product stream into one or more relatively benzene-rich fractions and one or more relatively benzene-lean fractions; and hydrogenating the one or more relatively benzene-rich fractions to produce a cyclohexane-rich effluent, at least a portion of which cyclohexane-rich effluent is recycled to constitute a portion of the reformer feedstock.
Claims21
A catalytic reforming process comprising:
- reforming a reformer feedstock that includes a naphtha stream in the presence of a catalyst to produce a gasoline reformate product stream;
- splitting the gasoline reformate product stream into one or more relatively benzene-rich reformate fractions and one or more relatively benzene-lean reformate fractions;
- recovering the one or more relatively benzene-lean reformate fractions as a first reformate gasoline pool component;
- hydrogenating the one or more relatively benzene-rich fractions to produce a cyclohexane-rich hydrogenated reformate effluent;
- recycling a portion of the cyclohexane-rich hydrogenated reformate effluent to constitute a portion of the reformer feedstock;
- and
- recovering the remaining portion of the cyclohexane rich hydrogenated reformate effluent as a second gasoline pool reformate component.
