Abstract
A process for reforming a hydrocarbon fraction having a limited proportion of C.sub.9 + hydrocarbons. A hydrocarbon fraction is separated into a light fraction and a heavy fraction, the light fraction containing less than 10% by volume of C.sub.9 + hydrocarbon. The light fraction is reformed in the presence of a monofunctional catalyst, and the heavy fraction is reformed in the presence of a bifunctional catalyst.

A hydrocarbon reforming process comprising reforming a hydrocarbon fraction under reforming conditions in the presence of a monofunctional catalyst, said hydrocarbon fraction comprising an amount not greater than about 10% by volume C.sub.9 + hydrocarbons, and being selected from a group of fractions consisting of a C.sub.6 fraction, a C.sub.7 fraction, a C.sub.8 fraction, a C.sub.6 -C.sub.7 fraction, a C.sub.7 -C.sub.8 fraction, a C.sub.6 -C.sub.8 fraction, and a fraction consisting essentially of the C.sub.6 and C.sub.8 hydrocarbons.
A process for reforming a hydrocarbon feed comprising:
- (a) separating a first fraction of said hydrocarbon feed into:
- (i) a light fraction comprising an amount less than about 10% by volume C.sub.9 + hydrocarbons, said light fraction being selected from the group consisting of a C.sub.6 fraction, a C.sub.7 fraction, C.sub.8 fraction, a C.sub.6 -C.sub.7 fraction, a C.sub.7 -C.sub.8 fraction, a C.sub.6 -C.sub.8 fraction, and a fraction consisting essentially of C.sub.6 and C.sub.8 hydrocarbon;
- and
- (ii) a heavy fraction comprising a range of hydrocarbons wherein the lowest carbon number hydrocarbon is one number higher than the highest carbon number hydrocarbon of the light fraction;
- and
- (b) reforming said light fraction under reforming conditions in the presence of a monofunctional catalyst.
