    摘要: An improved zeolite catalyst containing at least one noble metal and at least one alkali metal wherein the amount of the latter component exceeds the cationic exchange capacity of the zeolite has been found to be highly useful for catalytic reforming.

    摘要: A method for activation of an organic cation-containing crystalline catalyst is disclosed. The method includes contacting the catalyst with steam under conditions to decompose the organic cations, which result in the activation of the catalyst. The method has the advantage that organic cations are converted to non-hazardous by-products such as ammonia and light hydrocarbons such as ethylene. These are more easily controlled by environmental control schemes than higher molecular weight by-products resulting from traditional activation methods (nitrogen or nitrogen/air). The steamed catalyst can optionally be calcined to remove any organic material which may remain after steaming.For instance, a major product which results from decomposting the tetraethylammonium organic cations in zeolite .beta. is ethylene. The ethylene can be subsequently converted into carbon dioxide and water by oxidation.

    摘要: Petroleum resid is upgraded in an improved process to produce a low pour point 650.degree.-775.degree. F. fraction without disturbing the product characteristics of other distillate boiling range fractions. The 650.degree.-775.degree. F. fraction is dewaxed separately from the remaining hydrodesulfurized product.
