    摘要: Living plants and animals synthesize and often accumulate a wide variety of organic materials having a molecular weight greater than 150. These include different chemical types such as natural hydrocarbons including rubbery substances, natural resins, and natural glycerides such as oils and fats. These substances, formed in the anabolic process, are collectively called "anabolites".This invention provides a process for catalytically converting certain anabolites to liquid hydrocarbons useful for the manufacture of fuels such as gasoline and chemicals such as para-xylene. Crystalline aluminosilicate zeolites having an effective pore size of greater than about 5 Angstrom units are useful catalysts.

    摘要: An improved Fischer-Tropsch process for hydrocarbon synthesis operated in the fluid mode of the Sasol's Synthol Process provides increased diesel and heavier hydrocarbon yield wherein a Fischer-Tropsch synthesis catalyst modified by a minor amount of a zeolite catalyst selectively converts enough waxy product to prevent adhesion between catalyst particles which might interfere with catalyst flow thereby permitting maximization of diesel oil and heavy hydrocarbon yield.

    摘要: A process is disclosed for upgrading a naphtha which has been subjected to a reforming process which involves contacting said reformed naphtha together with added hydrogen with a crystalline aluminosilicate zeolite having a pore size of about 4.5 to 6 Angstrom units and a silica to alumina ratio of at least 3, said aluminosilicate having hydrogenation/dehydrogenation activity. Another embodiment of the invention resides in mixing a reforming catalyst with said crystalline aluminosilicate zeolite.

    摘要: The present invention relates to siliceous zeolite catalysts produced by a method which includes selecting an amount of aluminum framework species to be retained in a zeolite catalyst product, and use of a silicon substitution treatment to replace more reactive framework species used to control aluminum framework concentration. This technique substantially preserves the selected amount of the aluminum framework species. The zeolite product obtained has high reactivity and stability.
