    摘要: A process of concurrently dedusting and upgrading particulate laden raw, whole retort oil is provided which comprises the steps of: retorting solid hydrocarbon-containing material such as oil shale to liberate an effluent stream of dust laden hydrocarbons; injecting the dust-laden retort effluent product stream into a catalytic hydrotreater; agitating the product stream in the hydrotreater to constantly maintain the particulates in suspension within the oil; catalytically hydrotreating the agitated product stream in the presence of a hydroprocessing gas at a pressure of from 500 to 3000 psi, a temperature of from 650.degree. to 850.degree. F. and a space velocity of from 0.1 to 6.0 hr.sup.-1, whereby the suspended particulates are agglomerated to facilitate solid-liquid separation and substantial amounts of sulfur and nitrogen contaminants are simultaneously removed from the resulting ungraded oil; and mechanically separating the agglomerated particulates from the upgraded whole oil. The product oil may be further upgraded either by treatment with aqueous sulfuric acid or by hydrotreatment.

    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: 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.
