Process for producing a highly paraffinic diesel fuel having a high iso-paraffin to normal paraffin mole ratio

   
   

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.

Процесс для производить тепловозное топливо имея по крайней мере 70% C.sub.10+ парафинирует, при котором исо-parafin к нормальному коэффициенту моли парафина 5:1 и высокими. Это тепловозное топливо произведено мимо от питания содержа по крайней мере нормальный 40% C.sub.10+ парафинирует и по крайней мере нормальный 20% C.sub.26+ парафинирует. Произведено путем контактировать то питание внутри зона реакции isomerization/cracking питание при катализатор состоя из SAPO-11 и платины in the presence of водопод (коэффициент hydrogen:feed от от 1.000 до 10.000 SCFB) на температуре от 340.degree. C к 420.degree. C, давление от 100 psig к 600 psig, и жидкостной всечасной скорости космоса от 0.1 hr.sup.-1 к 1.0 hr.sup.-1.
