    摘要: A catalytic cracking catalyst and process which tolerates high levels of vanadium and coke precursors in the feed is disclosed. A zeolite in an alumina free binder or coating, preferably silica, is used as the cracking catalyst. RE-USY in silica is especially preferred as it has a low affinity for vanadium, low coking characteristics and high stability. Preferably a vanadium getter additive is present as separate particles to act as a vanadium sink. The catalyst and process may be used in fluidized bed catalytic cracking (FCC) or in moving bed catalytic cracking units. A method of making a coated catalyst, by adding a layer of an alumina free material to a core of alumina containing cracking catalyst is also disclosed.

    摘要: An FCC or fluidized catalytic cracking process and apparatus for converting heavy metals laden crudes is disclosed. The heavy feed, conventional catalyst and an additive or vanadium getter contact the feed in a riser reactor. The additive is segregated from conventional FCC catalyst upstream of the conventional FCC regenerator. An elutriating, upflow riser reactor may be used with a coarse, rapidly settling getter. A fine, slowly settling getter may be used, with getter segregation achieved by using an elutriating cyclone on the riser outlet, an elutriating catalyst stripper, a sieve, or the like. The spent getter may be used once through, regenerated in a separate getter regenerator, or used as a source of fuel. Alumina and sponge coke are preferred getters.

    摘要: Akylation product is contacted with a purification medium in a liquid phase pre-reaction step to remove impurities and form a purified stream. The purified stream may then be further processed by liquid phase transalkylation to convert the polyalkylated aromatic compound to a monoalkylated aromatic compound. The process may use a large pore molecular sieve catalyst such as MCM-22 as the purification medium in the pre-reaction step because of its high reactivity for alkylation, strong retention of catalyst poisons and low reactivity for oligomerization under the pre-reactor conditions. Olefins, diolefins, styrene, oxygenated organic compounds, sulfur containing compounds, nitrogen containing compounds and oligomeric compounds are removed.
