Abstract
A process for producing a diesel fuel having at least 70% C.sub.10+ paraffins, wherein the iso-paraffin to normal paraffin mole ratio is 5:1 and higher. This diesel fuel is produced by from a feed containing at least 40% C.sub.10+ normal paraffins and at least 20% C.sub.26+ normal paraffins. It is produced by contacting that feed in an isomerization/cracking reaction zone a feed with a catalyst comprising a SAPO-11 and platinum in the presence of hydrogen (hydrogen:feed ratio of from 1,000 to 10,000 SCFB) at a temperature of from 340.degree. C. to 420.degree. C., a pressure of from 100 psig to 600 psig, and a liquid hourly space velocity of from 0.1 hr.sup.-1 to 1.0 hr.sup.-1.
