    摘要: An integrated process for converting a hydrocarbon feedstock having components boiling above about 100° C. into steam cracked products is described. The process first involves passing the feedstock to a hydrotreating zone at a pressure in the range of from about 400 psig to about 1,250 psig to effect substantially complete decomposition of organic sulfur and/or nitrogen compounds. The product from the hydrotreating zone is passed to a steam cracking zone. Hydrogen and C1-C4 hydrocarbons, steam cracked naphtha, steam cracked gas oil and steam cracked tar are recovered, where the amount of steam cracked tar produced is reduced by at least about 15 percent, basis the starting hydrocarbon feedstock which has not been subject to hydrotreating.

    摘要: The present invention relates to catalysts suitable for hydrogenating aromatics and olefins in hydrocarbon feedstocks boiling between about 125.degree. C. and about 625.degree. C. as well as the process for carrying out the hydrogenation. The catalysts consist of one or more Group VIII noble metal(s) on a support wherein the support is a Y-type zeolite prepared by contacting a starting Y-type zeolite having a unit cell size less than about 24.65, preferably less than about 24.4 angstroms, a silica to alumina molar ratio greater than about 5, preferably by greater than about 25 and an alkali metal content of less than about 0.30, preferably less than about 0.15 percent (basis metal) with one or more aqueous solution(s) comprising alkali(ne-earth) metal ions under conditions sufficient to provide a final alkali metal content (measured in terms of gram equivalent weight per gram of zeolite) of at least about 1.5 times greater than the alkali metal content (measured in terms of gram equivalent weight per gram of zeolite) of the starting zeolite. Preferred Group VIII metals are platinum and palladium and sodium is a preferred alkali(ne-earth) metal.

    摘要: This invention provides an integrated process for converting a hydrocarbon feedstock having components boiling above 300.degree. F. into liquid fuel products boiling in the range of from about 80.degree. F. to about 700.degree. F., which process comprises passing said feedstock to a first stage hydrocracking zone to effect decomposition of organic sulfur and/or nitrogen compounds, passing a portion of the product from said first stage hydrocracking zone to a second stage hydrocracking zone, simultaneously passing the remaining portion of said product from said first stage hydrocracking zone to an aromatics saturation zone, and subsequently passing the product from said hydrocracking zone and said aromatics saturation zone to one or more fractionating zones wherein said products are separated into a tops fraction and a bottoms fraction, with the tops fraction being separated into light gasoline, naphtha, jet fuel and diesel fuel products, and a portion or all of the bottoms fraction being recycled to the hydrocracking zone and/or the aromatics saturation zone following the optional removal of heavies and polynuclear aromatics.
