    摘要: Monoalkyl benzene having a side chain of at least two carbon atoms is converted to dialkyl benzene having side chains of shorter length than the charge and containing a proportion of para dialkyl benzene in excess of the thermodynamic equilibrium value by reaction over a dual function catalyst comprising a noble metal from Group VIII of the Periodic Table and a crystalline aluminosilicate zeolite of high silica/alumina ratio above 12, a constraint index of 1 to 12, which aluminosilicate is in a state to restrict diffusion of ortho xylene.

    摘要: A metallic reforming catalyst, consisting of platinum and iridium or platinum, iridium and copper on a porous carrier provides excellent conversion of naphtha to C.sub.5.sup.+ product. A method of incorporating the metals or metal compounds on the carrier and preparing the finished catalyst using dimethyl sulfoxide is a novel procedure and provides unexpected catalytic properties. Novel reforming operations using these catalysts under moderate or severe conditions do not drastically alter the product yield.

    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.
