    摘要： Hydrocarbon feeds are converted into hydrocarbon products by contact at suitable conversion conditions with new and novel, highly active catalyst composites formed from crystalline alumino-silicate zeolites within which transition metal cations are deposited, i.e., exchanged or impregnated, and then activated, in novel manner. The catalysts are formed by ionexchanging, or impregnating, an alkali, alkaline earth or other form, e.g., a hydrogen form, of the crystalline aluminosilicate zeolite base, natural or synthetic, with salt solutions of Group IB, IVB, VB, VIB, VIIB and VIII metals; heat-treating, or pretreating, to form chemical complexes at the ion-exchange sites, to drive off moisture and absorbed oxygen, and then activating and further modifying the complex by contacting the so-formed composite with covalent or liquid soluble forms, and preferably monomeric forms, of organometallic compounds capable of entering into the pores of the zeolite, and wherein the metal constituent is selected from Groups I, II and III, and preferably Groups IA, IIA and IIIA, of the Periodic Chart of the Elements. Preferably, the so-activated composite is then treated in the presence of hydrogen at elevated temperature to fix the catalyst in its most active and stable form. Suitably, a mixed metal modification of the catalyst can be formed by use of an additional metal component, or components, which can be contacted and composited with the catalyst before or after, but preferably before, the activation and fixation steps.
