    摘要： A catalyst is described for selective gas phase hydrogenation of acetylenic compounds containing 2 or 3 carbon atoms to the corresponding ethylenic compounds. The catalyst, in the form of spherules or extrudates, comprises palladium, at least one metal from group IB, optionally at least one alkali or alkaline-earth metal, and alumina, in which at least 80% of the palladium and at least 80% of the element from group IB are present in a volume at the periphery of the catalyst defined between a spherical or cylindrical surface with radius r.sub.1 corresponding to the average radius of the spherules or extrudates of the catalyst and a spherical or cylindrical surface with radius r.sub.2 at least equal to 0.8 r.sub.1, the catalyst having a group IB metal/palladium ratio of 0.4 to 3 by weight. Further, it is advantageous for this catalyst that at least 30% of the metal particles contain both palladium and silver.

    摘要： A process and apparatus for treating raw gasoline from catalytic cracking to obtain gasoline with the qualities required for use as motor fuel comprises selective hydrogenation followed by stabilization and optional cooling of the effluent, then sweetening followed by degassing to obtain a dedienized, stabilized and sweetened gasoline. The hydrogenation catalyst preferably comprises 0.1-1% of palladium deposited on a support, sweetening is preferably carried out on a solid catalyst containing an aluminosilicate of an alkali metal (for example sodalite), a metal chelate and activated charcoal. The product from this process can be placed directly in the gasoline pool or, advantageously, fractionated to obtain one or more cuts which can be used as feeds for etherification.

    摘要： Catalytic cracking gaseolines are treated by: (a) fractionating the raw gasoline cut into two cuts; (b) optional selective diene hydrodenation of the light cut, then mild hydrotreatment and stripping; (c) sweetening the light cut which is conducted before the mild hydrotreatment step by contact with a supported catalyst containing 0.1-1% by weight of palladium, or after the mild hydrotreatment step and which is then an extractive sweetening step, or with a catalyst having an alkaline base optionally incorporated and also an oxidizing agent. The heavy gaseoline fraction is optionally desilphurized in a hydrotreatment unit. The desulpurized and sweetened light gaesoline can be added to the gasoline pool either directly or mixed with the desulphurized heavy gaseoline cut.
