    摘要： A gaseous mixture of carbon monoxide and hydrogen is passed in contact over a first catalyst bed comprising an iron or cobalt containing Fischer-Tropsch catalyst in combination with a crystalline aluminosilicate of the class of crystalline zeolite represented by ZSM-5 so as to obtain a liquid hydrocarbon product having a boiling range of less than 400.degree. F. at a 90% overhead and being a predominantly olefinic product. The total products from said contact including said liquid hydrocarbon product are then converted over a second catalyst bed containing HZSM-5 to obtain a highly aromatic product, i.e., greater than 20 weight percent.

    摘要： A method is disclosed for the conversion of a syngas to a liquid hydrocarbon product having a boiling range of less than 400.degree. F. at a 90% overhead and being a predominantly olefinic product, wherein the olefins have substantially internal double bonds. The method for accomplishing this stated result involves an improvement in the method for the conversion of synthesis gas by contacting the same with a catalyst composite comprising a mixture of a Fischer-Tropsch catalyst and a volume excess of an acidic catalyst, e.g., silica-alumina or a crystalline aluminosilicate zeolite and wherein the activity of the acidic component is balanced with the activity of the Fischer-Tropsch component so as to maximize the yield of desired olefinic product.

    摘要： An improved processing technique is provided for conversion of olefins of 2 to 4 carbon atoms to product comprising high octane gasoline components. Embodiments of the present improved processing technique include conversion of light olefins to high octane olefinic gasoline components, and conversion of light olefins to high octane aromatic gasoline components.The improved technique comprises contacting an appropriate light olefin feedstock with a catalyst comprising a crystalline aluminosilicate zeolite characterized by a silica/alumina mole ratio of at least 12 and a constraint index, hereinafter defined, within the approximate range of 1 to 12 in the presence of a relatively large amount of co-fed water. The amount of co-fed water is maintained at from about 0.5 to about 15 moles of water/mole of olefin feedstock.

    摘要： A hydrous aluminosilicate adsorbent composition in which the active adsorbent is a mixture of non-fibrous clay with non-fibrous zeolite. The composition is useful as a feed supplement in animal husbandry, and as a topical adsorbent for veterinary use. The mixture has a high capacity for adsorption of ammonium cations, and a synergistically high selectivity for their adsorption. Beneficial effects as feed supplement may arise from lowering the amount of ammonia passed to the liver from the alimentary canal.
