    摘要: The present invention provides a process for alkylating an isoparaffin with an olefin comprising contacting an isoparaffin having from 4 to 8 carbon atoms with an olefin having from 2 to 12 carbon atoms in an alkylation reaction zone at temperature from about -20.degree. C. to about 150.degree. C. with an alkylation catalyst complex comprising a Lewis acid and an inorganic, porous crystalline phase material having, after calcination, a d-spacing greater than about 18 Angstrom Units and having a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 50 torr and 25.degree. C., wherein the molar ratio of said isoparaffin to said olefin is from about 1 to about 250 to evolve a product stream containing C.sub.5 +alkylate. In a preferred embodiment, the alkylation catalyst complex comprises a Lewis acid and an inorganic, porous crystalline phase material having, after calcination, a hexagonal arrangement of uniformly-sized pores having diameters of at least about 13 Angstrom Units and exhibiting a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units.

    摘要: This invention is directed to an extinction recycle naphtha hydrocracking processes. Large pore zeolite catalysts with Constraint Indices less than 2, such as USY or beta, which are loaded with noble metals such as Pt or Pd or with transition metals such as Ni in combination with Mo or W are employed. Preferably, low hydrogen partial pressures, and a feedstock relatively rich in hydrogen and low in aromatics content, are used, in order to extend catalyst cycle length.
