    摘要: A method is provided for enhancing the shape selectivity of a crystalline zeolite having a silica-to-alumina mol ratio greater than 10. The method consists of treating the zeolite with an ammonium fluoride solution at moderately elevated temperature, in the absence or in the presence of a matrix. The products are useful as shape-selective sorbents, and also as shape-selective catalysts for organic reactions including catalytic dewaxing.

    摘要: An improved hydrotreating catalyst, and a process for using thereof, comprises a conventional Group VIA and Group VIIIA metal metal oxide or metal sulfide, deposited on an inorganic refractory support and about 0.1% by weight to about 7% by weight of the catalyst of a promoter comprising a halogenated metal selected from the Group consisting of halogenated metals of Group IB, IIB, IIIB, titanium and tin. The presence of the promoter results in greater degree of desulfurization and in CCR reduction of hydrocarbon feedstocks, especially highly aromatic petroleum residua and synthetically-derived hydrocarbons, e.g., coal liquids.

    摘要: A zeolite, its method of preparation and use is disclosed. The zeolite is characterized by a silica to alumina mole ratio greater than 12 and a Constraint Index of 1 to 12. The zeolite undergoes controlled alumina extraction by treatment with, e.g., strong mineral acid or chelating agent. Removal of aluminum increases the acid activity of the zeolite.

    摘要: A process for catalytically cracking a hydrocarbon feed in a reaction zone under catalytic cracking conditions in the absence of added hydrogen with a catalyst comprising a conventional cracking catalyst. The improvement comprises adding to the conventional cracking catalyst a thermally treated zeolite having a mole ratio of SiO.sub.2 :Al.sub.2 O.sub.3 of about 10:1 to 100:1 and a constraint index of about 1 to 12. Thermal treatment reduces the additive zeolite's alpha activity to about 1 to 10 prior to use.

    摘要: Liquid product rich in benzene, toluene and xylene and having a substantially lower mid-boiling point than heavy reformate feedstock or similar feedstock, such as, for example, from pyrolysis gasoline, of a class having an initial boiling point between about 230.degree. F and about 250.degree. F and an end point between about 350.degree. F and about 430.degree. F, and gaseous product rich in light olefins and isoparaffins which is good alkylation plant feed are produced by contacting said heavy reformate feedstock or said similar feedstock with a porous acid-active zeolite catalyst having a fluid activity index of at least about 18 in a fluidized catalyst system absent added hydrogen at a temperature of from about 800.degree. F to about 1200.degree. F, a catalyst/oil (i.e. heavy reformate or similar feedstock) weight ratio of from about 0.5 to about 40 and a catalyst residence time of from about 0.1 second to about 20 seconds.
