Fremgangsmåte for selektiv ringåpning for fremstilling av dieseldrivstoff med ökt cetantall

摘要

A process, preferably in a counter-current configuration, for selectively cracking carbon-carbon bonds of naphthenic species using a low acidic catalyst, preferably having a crystalline molecular sieve component and carrying a Group VIII noble metal. The diesel fuel products are higher in cetane number and diesel yield.
