    摘要： The present invention relates to a novel alkylation catalyst complex and to alkylation processes employing such a catalyst complex. More specifically, the invention relates to a novel catalyst complex comprising a BF.sub.3 :H.sub.3 PO.sub.4 adduct, and at least one polar hydrocarbon formed in situ. The catalyst complex may optionally include water as well as an added solubilizing agent. The invention further includes a pretreatment method for enhancing the isoparaffin selectivity of a catalyst complex containing a BF.sub.3 :H.sub.3 PO.sub.4 adduct.

    摘要： A layered catalyst suited to the catalytic cracking of heavy feeds comprises a core and a shell. The shell comprises at least 5 wt % of at least 1 molecular sieve having openings of at least 8 angstroms. The core comprises at least 10 wt % of at least 1 molecular sieve having openings comprising a 12 or less-membered ring and has a reduced, if any, content of said molecular sieve having openings of at least 8 angstroms, relative to its concentration in the shell. Suitable molecular sieve materials having openings of at least 8 angstroms include MCM-41, VPI-5, MCM-9 and layered metal oxides, e.g., pillared clays. The required molecular sieve of the core can include zeolite Y, Ultrastable Y or intermediate pore size zeolites such as ZSM-5. The shell which may further contain a metals passivator can act as a metals sink, and can remove metals from the unit by attrition. The catalyst is preferably prepared by forming the core and then coating or encapsulating the core with a shell material. The shell may also comprise an attritable coating of an amorphous rare earth oxide, aluminum oxide and aluminum phosphate composite, which traps metals.
