    摘要: 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 and a 345.degree. C.+ products fraction is recycled to the cracking zone. The catalyst is an amorphous silica-alumina or a zeolitic material which is iso-structural to faujasite. 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.

    摘要: A process which comprises recracking a cracked naphtha feed containing up to about 60 percent, suitably from about 20 to about 40 percent olefins, over a crystalline aluminosilicate zeolite catalyst to further crack the naphtha and saturate at least about 50 percent of the olefins, preferably from about 90 percent to about 100 percent of the olefins, based on the weight of said cracked naphtha feed. In a preferred combination a gas oil is catalytically cracked in a first stage to produce a cat cracked naphtha product of high olefin content, and an intermediate boiling component thereof is recracked as a feed in a second stage over a zeolite catalyst to saturate the olefins, and hydrodenitrogenate and hydrodesulfurize said cat cracked naphtha. The recracked cat cracked naphtha is then hydrotreated at low to mild severities and then catalytically reformed (hydroformed) to produce high octane gasoline.

The catalyst comprises an admixture of composite particles, one present in major concentration for providing principally cracking and combustion promoting functions, and the other present in minor concentration for providing principally sulfur fixation and transfer functions. The particle present in major concentration, on the one hand, is constituted essentially of one or more Group VIII noble metals, preferably platinum, composited with a support comprised of a crystalline alumino silicate component distributed in an active cracking catalyst matrix, suitably one constituted of silica-alumina. The minor component particle, on the other hand, is comprised of one or more Group II-A metals, preferably magnesium, composited with a support, suitably silica-magnesia or silica-alumina, which may also contain a crystalline aluminosilicate zeolite component dispersed within thesilica-magnesia or silica-alumina support matrix.
