    摘要: A catalytic cracking catalyst for converting a hydrocarbon feedstock at elevated temperature in the substantial absence of hydrogen, into lower average molecular weight, lower boiling hydrocarbons useful as transportation fuels. The catalyst is a composite of a crystalline aluminosilicate zeolite in concentration ranging as high as about 80 percent, based on the total weight of the catalyst, within a mesoporous silica-alumina matrix. The matrix, preferably, is constituted of silica sols modified by alumina and clay and it is characterized as of polymodal pore size distribution, as measured by mercury porosimetry, a first mode wherein at least 75 percent, preferably about 80 percent to 90 percent, of the pore volume measured between 45 Angstroms and 2000 Angstroms is in pores greater than 160 Angstroms in diameter, and a second mode wherein up to about 20 percent of the pore diameters are greater than 100 Angstroms but less than 160 Angstroms in diameter. These catalysts are highly active, and selective in the production of olefins without high coke made. The attrition-resistance of these catalysts, as measured by the Davison Index, is quite low, ranging generally from about 1 to about 8, more generally from about 1 to about 5, or less.

    摘要: The propylene production of a fluid catalytic cracking unit employing a large pore zeolite cracking catalyst, produces more propylene by adding a naphtha cracking riser and a medium pore zeolite catalytic component to the unit, and recycling at least a portion of the naphtha crackate to the naphtha riser. The large pore size zeolite preferably comprises a USY zeolite and the medium pore size is preferably ZSM-5. Propylene production per unit of naphtha feed to the naphtha riser is maximized, by using the 60–300° F. naphtha crackate as the feed.

    摘要: A process for producing polymers from olefins selectively produced by a two stage process for selectively producing C2 to C4 olefins from a gas oil or resid is disclosed herein. The gas oil or resid is reacted in a first stage comprising a fluid catalytic cracking unit wherein it is converted in the presence of conventional large pore zeolitic catalyst to reaction products, including a naphtha boiling range stream. The naphtha boiling range stream is introduced into a second stage comprising a process unit containing a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone. The naphtha feed is contacted in the reaction zone with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures ranging from about 500 to 650° C. and a hydrocarbon partial pressure from about 10 to 40 psia. Vapor products are collected overhead and the catalyst particles are passed through the stripping zone on the way to the catalyst regeneration zone. Volatiles are stripped with steam in the stripping zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, which is then recycled to the reaction zone.
