    摘要: A method for converting a hydrocarbonaceous feedstock to a lower boiling temperature product is described which comprises suspending metal sulfide particles and oxide particles in a reaction zone including hydrogen and the hydrocarbonaceous feedstock at hydrocracking conditions. The metal sulfide particles and the oxide particles are introduced into the reaction zone through particle precursor fluids which precipitate upon heating to form the particles. The metal sulfide particles contain sulfidable transition metals. The oxide particles contain oxidisable elements such as magnesium, aluminum, silicon, phosphorous, calcium, scandium, titanium, gallium, germanium, zirconium, cerium, and mixtures thereof and are not hydrogenation catalysts under the reactor conditions. The oxide particles resist being chemically reduced by reducing agents in the reaction zone. Surprisingly, the presence of the oxide particles is associated with a significant reduction of coke production in the reaction zone. A hydrogenation catalyst precursor comprising a hydrocarbonaceous feedstock, a sulfide particle precursor fluid, and an oxide particle precursor fluid is also described.

    摘要: A method for converting a hydrocarbonaceous feedstock to a lower boiling product is described which comprises suspending metal-impregnated carbonaceous particles in a reaction zone including hydrogen and the hydrocarbonaceous feedstock at hydrocracking conditions. The metal impregnated on the particles may be sulfided in the reaction zone. The impregnated particles are shown to be surprisingly selective catalysts, and anomalous ranges of particle size and concentration are identified. Methods for preparing the particles are additionally presented.

    摘要: Adsorbent compositions for vapor-phase adsorption processes, which are selective for para-xylene. Such compositions can be used in gas-phase adsorption processes for the separation of para-xylene or the separation of para-xylene and ethylbenzene from mixed xylenes or a C8 aromatic mixture, respectively. The adsorbent compositions generally comprise materials of a molecular sieve material and a binder, wherein the adsorbent composition has a macropore volume of at least about 0.02 cc/g and a mesopore volume of less than about 0.20 cc/g.

    摘要: This invention comprises a reforming catalyst and process with an unsulfided catalyst comprising Zeolite L, in which the cationic sites have been exchanged to contain potassium or barium or both; a Group VIII noble metal and rhenium, where the ratio of noble metal to rhenium is from about 0.1:1 to about 10:0. This catalyst gives improved selectivity toward aromatics formation and has improved sulfur tolerance compared to other L zeolite reforming catalysts.

    摘要: Disclosed herein are methods of making xylene isomers. The methods generally include contacting an aromatics-comprising feed with a non-sulfided catalyst under conditions suitable for converting the feed to a product comprising xylene isomers. The catalyst includes a support impregnated with a hydrogenation component. The support includes a macroporous binder and a sieve selected from the group consisting of a medium pore sieve, a large pore sieve, and mixtures thereof. The selection of the sieve will depend upon the size of the molecules in the feed, intermediate, and product that can be expected from the catalytic reactions. When the molecules are expected to be large, a large pore sieve should be used. In contrast, when the molecules are expected to be smaller, either a large pore sieve, a medium pore sieve, or a mixture thereof may be used. The macropores within the support have been found to be especially beneficial because they help to overcome diffusional limitations observed when utilizing highly-active catalysts lacking such macropores.
