    摘要: A process for the hydroconversion and hydrodenitrogenation of 1050*F.+ heavy crudes and residua. Hydroconversion of the 1050*F.+ materials is conducted in a first or initial reaction zone with a large pore catalyst to provide increased 1050*F.-or gas oil yield of high nitrogen content, and the product is treated in a subsequent reaction zone with an aluminum phosphate catalyst. The process combination provides overall increased gas oil yield of low nitrogen content.

    摘要: A desulfurization catalyst which comprises a cogel of catalytically active amounts of a hydrogenation component which includes a Group VIB or VIII metal, or both, and a Group IVA metal, notably germanium, and a porous inorganic oxide support, notably alumina. Such catalysts are particularly effective in the hydrodesulfurization of naphthas, gas oils, whole heavy crudes and residua.

    摘要: The strip tensile strength of nonwoven mat battery separators of polypropylene fibers having a diameter from about 1 to about 10 microns is increased, for example, to strengths greater than 4,000 m, by fuse-bonding, as by calendering or point-bonding, at least a portion of the fibers of the mat at temperatures within the range from about 250*F to about 325*F, preferably, from about 280*F to about 315*F, while the mat is subjected to pressure sufficient to prevent shrinkage of the fibers in the mat.
