A process for producing a diesel fuel having at least 70% C10+ 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% C10+ normal paraffins and at least 20% C26+ 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° C. to 420° C., a pressure of from 100 psig to 600 psig, and a liquid hourly space velocity of from 0.1 hr−1 to 1.0 hr−1.
A process for producing a diesel fuel comprising contacting in an isomerization/cracking reaction zone a feed having at least 40% C10+ normal paraffins and at least 20% C26+ paraffins with a catalyst comprising at least one Group VIII metal on a catalytic support and a hydrocracking catalyst to produce a product having an iso-paraffin to normal paraffin mole ratio of at least 5:1 and having a diminished level of C26+ paraffins.
A process for producing a diesel fuel comprising contacting in a isomerization/cracking reaction zone a feed having at least 40% C10+ normal paraffins and at least 20% C26+ paraffins with a layered bed system comprising a hydrocracking catalyst, and a catalyst comprising at least one Group VIII metal and a molecular sieve on a catalytic support to produce a product having an iso-paraffin to normal paraffin mole ratio of at least 5:1 and having a diminished level of C26+ paraffins.
