    摘要: A fluid catalytic cracking catalyst made from microspheres that initially contain kaolin, a dispersible boehmite alumina and a sodium silicate or silica sol binder. The kaolin portion contains hydrous kaolin and optionally kaolin which has been calcined through its characteristic exotherm. Calcination of the hydrous clay to metakaolin and formation of in-situ zeolite by treatment with sodium silicate yields a catalyst containing Y-faujasite and transforms the dispersible boehmite into a transitional alumina which contains a gamma alumina phase. The transitional alumina may contain a delta alumina phase as well. The catalyst can be used to crack resid or resid-containing feeds as the alumina phase formed from the dispersible boehmite passivates nickel and vanadium contaminants.

    摘要: A heavy fraction oil is catalytically cracked by contacting the oil with a catalyst mixture consisting of 60 to 95 wt % of a base cracking catalyst containing an ultra stable Y-type zeolite and less than 0.5 wt % of rare-earth metal oxide, and 5 to 40 wt % of an additive containing a shape-selective zeolite, in a fluid catalytic cracking apparatus having a regeneration zone, a down flow-type reaction zone, a separation zone, and a stripping zone, and under conditions that a reaction zone outlet temperature is in the range of 580 to 630null C., the catalyst/oil ratio is in the range of 15 to 40 wt/wt, and the contact time of hydrocarbons in the reaction zone is in the range of 0.1 to 1.0 seconds. According to the fluid catalytic cracking process, the yield of light-fraction olefins can be enhanced.

    摘要: The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction catalyst composition comprising a porous molecular sieve which contains a metal in an oxidation state above zero within the interior of the pore structure of the sieve as well as a cerium component which enhances the stability and sulfur reduction activity of the catalyst. The molecular sieve is normally a faujasite such as USY. The primary sulfur reduction component is normally a metal of Period 3 of the Periodic Table, preferably vanadium. The sulfur reduction catalyst may be used in the form of a separate particle additive or as a component of an integrated cracking/sulfur reduction catalyst.

The catalyst comprises (1) at least one solid acid component, (2) at least one metal-based component comprised of two or more elements from Groups 4-15 of the Periodic Table of the Elements and at least one of oxygen and sulfur, wherein the elements from Groups 4-15 and the at least one of oxygen and sulfur are chemically bound both within and between the groups and (3) at least one of at least one support, at least one filler and at least one binder. The process is such that the yield of hydrogen is less than the yield of hydrogen when contacting the hydrocarbons with the solid acid component alone.
