Abstract:
A process for preparing paraffins in the gasoline, middle distillate fuel and lube ranges, the process comprising;(a) combining a C2-5 containing paraffinic feedstock with a C20+ containing paraffinic feedstock; (b) combining the feedstock in step (a) with a catalyst bed which includes a dehydrogenation/hydrogenation catalyst and an olefin metathesis catalyst under conditions which dehydrogenate the paraffins to olefins, metathesize the olefins, and rehydrogenate the olefins, to provide a product stream that includes paraffins having molecular weight between those of the C2-5 paraffinic feedstock and the C20+ paraffinic feedstock, (c) isolating a first fraction rich in paraffins in the gasoline, middle distillate fuel and lube ranges from the product stream, (d) isomerizing at least a portion of the paraffins in the first fraction.
