A process for producing a debenzeneated gasoline blending stock from a benzene-containing refinery stream by using a dual function catalyst. The benzene-containing refinery stream contains at least 2 wt % of benzene is hydrogenated to cyclohexane and then isomerized to methylcyclopentane accompanied with C.sub.5 -C.sub.7 normal paraffins isomerized to isoparaffins, preferably in a single reactor or catalytic distillation reactor using dual function catalyst.

There is provided a process for regenerating a coked catalyst comprising a zeolite and a noble metal such as platinum. The process involves treating the coked catalyst under somewhat mild oxidation conditions, whereby a sufficient portion of the coke is removed from the catalyst to restore the hydrocarbon sorption properties of the zeolite component to the level observed in the non-coked form. Surprisingly, the original activity of the catalyst is substantially restored, even though a substantial amount of coke remains on the regenerated catalyst.
