    摘要: The invention concerns a process for eliminating arsenic from a hydrocarbon cut in which said cut is brought into contact with an absorption mass that is at least partially pre-sulfurized and comprises a support and lead oxide. The support, for example alumina, or said mass preferably has a specific surface area in the range 10 to 300 m2/g, a total pore volume in the range 0.2 to 1.2 cm3/g and a macroporous volume in the range 0.1 to 0.5 cm3/g. The lead content of said mass, expressed as lead oxide, is preferably in the range of 5% to 50% by weight. The fraction of the sulfurized mass preferably represents at least {fraction (1/20)}th of the total volume of the absorption mass.

    摘要: An aliphatic alkylate with a high octane number is prepared from a C4 catalytic cracking or steam-cracking fraction that contains mainly isobutane, isobutene, butene-1 and butenes-2 by: (a) hydro-isomerizing said C4 fraction, obtaining a mixture that contains for the most part butenes-2, isobutene and isobutane; (b) separating, by distillation of the hydro-isomerized fraction, of a butene-2-rich effluent that is collected at the bottom and an isobutane- and isobutene-rich effluent that is collected at the top; (c) sending said isobutene- and isobutane-rich effluent into a hydrogenation zone that produces an effluent that for the most part contains isobutane; (d) sending of said butenes-2-rich effluent that is derived from (b) and of said effluent that for the most part contains the isobutane that is derived from (c) into an alkylation zone producing, by addition of isobutane to butenes-2, an isooctane mixture that contains excess isobutane; (e) separating by distillation of excess isobutane, which comes out at the top, and alkylate with an improved octane number, which comes out at the bottom; and (f) recycling of the excess isobutane that is recovered in (e) upstream from hydrogenation (c) of the top effluent from the distillation of (b).

    摘要: A particulate selective hydrogenation catalyst for hydrogenating unsaturated diolefinic hydrocarbons to &agr;-olefinic hydrocarbons at rates which are at least 1.5 times higher than the rate of hydrogenation of &agr;-olefinic hydrocarbons to saturated compounds contains palladium distributed at the periphery of particles (spherules or extrudates), and at least one element selected from tin and lead. Further, the tin and/or lead is advantageously distributed at the periphery of the spherules or extrudates.
