Abstract:
A process for selectively producing diesel fuels from a hydrocarbon feed comprising contacting said hydrocarbon feed with a hydrogen containing gas in order to form a liquid product effluent, and contacting said liquid product effluent under superatmospheric conditions with a selective ring-opening catalyst comprisinga large pore crystalline molecular sieve material component having a faujasite structure and an alpha acidity of less than 1, anda group VIII noble metal component wherein the feed contains at least 50 wt. % naphthenes and less than 40 wt. % aromatics, and wherein said liquid product effluent is contacted with said selective ring-opening catalyst at a pressure ranging from about 400 psi to about 1000 psi, a temperature ranging from about 544.degree. F. to about 700.degree. F., a space velocity ranging from about 0.1 LHSV to about 10 LHSV, and a hydrogen circulation rate of about 1400 SCF/bbl to about 5600 SCF/bbl.
