FCC for producing low emission fuels from high hydrogen and low nitrogen and aromatic feeds |
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 a mixture of zeolite-Y and ZSM-5, or an amorphous acid catalytic material with ZSM-5, or a combination of all three. 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.
