    摘要: A catalytic composite of a refractory inorganic oxide whose bound surface hydroxyl group has reacted with a Friedel-Crafts type metal halide and whose acidity has been modified by the deposition of a monovalent metal cation, especially an alkali metal cation, or alkaline earth metal cation shows superior selectivity and a significantly decreased cracking tendency relative to similar catalysts without the monovalent metal or alkaline earth metal cation. The resulting alkylate from an isobutane-butene feedstock shows a substantial increase in research octane number relative to the alkylate formed by a similar catalyst which has not been so modified by an alkali or alkaline earth metal cation.

    摘要: This invention relates to hydrocarbon conversion process using a catalyst consisting essentially of a layered clay homogeneously dispersed in an inorganic oxide matrix. The clay is dispersed in such a way that the clay layers are completely surrounded by the inorganic oxide matrix. The inorganic oxide is selected from the group consisting of alumina, titania, silica, zirconia, P.sub.2 O.sub.5 and mixtures thereof. The clay can be a natural clay such as montmorillonite, a metal exchanged clay (Fe.sup.+3 exchanged) or a pillared clay such as aluminum chlorohydrate (ACH) pillared clay. The hydrocarbon conversion process is carried out by contacting a hydrocarbon feed with the catalyst at hydrocarbon conversion conditions to give a hydroconverted product. Examples of the hydrocarbon conversion processes are alkylation and hydrocracking.

    摘要: A hydrocarbon conversion process is disclosed which extends the useful life of a regenerable zeolite-containing hydrocarbon conversion catalyst. In one aspect of this process, a hydrocarbon feed containing fluorides is passed through a fluoride removal system which reduces the fluoride concentration of the feed to below 100 ppb. The hydrocarbon feed containing less than 100 ppb fluorine is then converted over a regenerable zeolite-containing hydrocarbon conversion catalyst. The zeolite-containing hydrocarbon conversion catalyst is regenerated with an oxygen-containing gas stream as necessary to burn off carbonaceous deposits on the catalyst so as to return the zeolite catalyst to a high level of activity.

    摘要: Methods are provided for producing low oxygen biomass-derived pyrolysis oil from carbonaceous biomass feedstock. The carbonaceous biomass feedstock is pyrolyzed in the presence of a steam reforming catalyst to produce char and pyrolysis gases. During pyrolysis, a portion of the oxygenated hydrocarbons in the pyrolysis gases is converted into hydrocarbons by steam reforming also yielding carbon oxides and hydrogen gas. The hydrogen gas at least partially deoxygenates a residual portion of the oxygenated hydrocarbons. Additional hydrogen gas may also be produced by water-gas shift reactions to deoxygenate the residual portion of the oxygenated hydrocarbons in the pyrolysis gases. Deoxygenation may occur in the presence of a hydroprocessing catalyst. A condensable portion of the pyrolysis gases is condensed to form low oxygen biomass-derived pyrolysis oil.
