ABSTRACT:
A fluid catalytic cracking process for producing relatively low emissions fuels. The feedstock is exceptionally low in nitrogen and aromatics and relatively high in hydrogen. The catalyst is an amorphous silica-alumina or a zeolitic material having a relatively small unit cell size. 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.
