    摘要： A catalytic reforming process comprising the catalytic conversion of hydrocarbons to aromatics, said process comprising treating a halided zeolite catalyst (hiz-cat) containing a Group VIII metal at commercial startup conditions and then reforming hydrocarbons, wherein said catalyst is prepared by washing a bound zeolite catalyst base or a bound zeolite catalyst before halide addition. A preferred hiz-cat is a non-acidic Pt K L-zeolite catalyst prepared by a process that includes the steps of preparing a calcined silica-bound K L-zeolite catalyst base; washing said bound zeolite catalyst base with a liquid comprising water; and incorporating Pt and halogen-containing compound(s) comprising chlorine and fluorine into said washed catalyst base. Ammonium chloride and ammonium fluoride are preferred halide sources.

    摘要： A catalytic reforming process using a halided zeolite catalyst containing platinum in a metal-coated reactor system where, prior to catalyst loading and reforming, halide acid is removed from the catalyst. The process comprises providing a reforming reactor system having a metal coating; providing a halided zeolite catalyst containing platinum prepared by a method which includes removing volatile halide acid; loading said catalyst into said reactor system; and catalytically reforming hydrocarbons to aromatics, wherein metal from the metal-coated reactor system does not deactivate the catalyst. The coating metal preferably comprises tin and the zeolite catalyst is preferably a platinum L-zeolite catalyst. The invention is also a method for reducing catalyst contamination from a metal which was used to coat a reactor system. The method comprises pretreating a halided catalyst with hydrogen to remove volatile halide acid. The resulting catalyst is then loaded into a metal-coated reactor system and hydrocarbons are converted.

    摘要： Provided is a method for removing residual sulfur from a hydrotreated naphtha feedstock. The process comprises contacting the naphtha feedstock with a first solid sulfur sorbent comprising a metal on a support to thereby form a first effluent. The effluent is then contacted with a sulfur conversion catalyst comprising a Group VIII metal in the presence of hydrogen, with the resulting effluent being contacted with a second solid sulfur sorbent containing a Group IA or IIA metal, to thereby lower the sulfur content of the feedstock to less than 10 ppb, and to as low as 1 ppb or less. The feedstock can then be safely used with highly sulfur sensitive zeolitic reforming catalysts without adversely affecting the useful life of the catalyst.
