摘要： The present invention relates to a catalyst comprising an extruded essentially alumina-based support, constituted by a plurality of juxtaposed agglomerates partially in the form of packs of flakes and partially in the form of needles, and comprising at least one catalytic metal or a compound of a catalytic metal from group VIB, and/or optionally at least one catalytic metal or compound of a catalytic metal from group VIII. The catalyst also comprises at least one dopant selected from the group formed by boron, phosphorous, silicon (or a silica different from that subsequently added to the support) and halogens. The invention also relates to its use in a fixed bed reactor, for hydrorefining and hydroconverting hydrocarbon feeds.

摘要： A catalyst for selective hydrogenation of unsaturated diolefinic and styrenic compounds in gasolines without hydrogenating the aromatic and mono-olerinic compounds is described. It can also eliminate marcaptans when they are present in these gasolines. The catalyst comprises particulate support on which palladium is deposited, distributed at the periphery of the catalyst particles, and at least one metal selected from molybdenum and tungsten, in the form of at least one oxide.

摘要： The method of the present invention involves a composition containing an intimate mixture of (a) metal oxide support particles and (b) a catalytically active metal oxide from Groups VA, VIA, or VIIA, its method of manufacture, and its method of use for converting alcohols to aldehydes. During the conversion process, catalytically active metal oxide from the discrete catalytic metal oxide particles migrates to the oxide support particles and forms a monolayer of catalytically active metal oxide on the oxide support particle to form a catalyst composition having a higher specific activity than the admixed particle composition.
