FCC for producing low emission fuels from high hydrogen and low nitrogen and aromatic feeds with Cr-containing catalyst

摘要

A fluid catalytic cracking process for producing relatively low emissions fuels, The feedstock is relatively low in nitrogen and aromatics and high in hydrogen content and the catalyst is an amorphous acidic catalytic material which is promoted with up to about 5000 wppm chromium. The feedstock can be characterized as having less than about 50 wppm nitrogen; greater than about 13 wt. % hydrogen; less than about 7.5 wt. % 2+ ring aromatic cores; and not more than about 15 wt. % aromatic cores overall.
