    摘要： A process for the preparation of a packed bed comprising an iron enriched cobalt catalyst for use in a Fischer-Tropsch reaction, the process comprising the steps of: (a) providing a packed bed with one or more catalyst particles comprising metallic cobalt; (b) contacting a part of the catalyst particle(s) in the packed bed with an iron containing compound. The process is preferably conducted in situ which conveniently results in an iron containing cobalt catalyst with a higher C5+ selectivity. In certain preferred embodiments the concentration of iron increases towards the surface of the resulting catalyst particles whereas the cobalt concentration is constant which further increases the selectivity of the catalyst to producing C5+ hydrocarbons.

    摘要： The invention provides active, affordable, durable, and sulfur-tolerant catalysts and related precursors and processes useful in hydrogen production. The catalysts have a wide applicability. For example, in one embodiment, the invention provides sulfur-tolerant catalysts which, when used in a catalytic fuel processor, will facilitate sufficient hydrogen generation within 30 seconds or so of automobile start-up to generate around 50 kW of fuel cell power. Catalysts of the instant invention are made by reducing a catalyst precursor comprising a support phase impregnated with one or more elemental transition metals, wherein: (a) the support phase is formed by dispersion of a monolayer on the surface of a high surface area alumina support; and (b) the monolayer comprises XOnYO2, where (1) XOn is a redox active metal oxide and n is either 1.5, 2, or 2.5 depending on the oxidation number of X, and (2) YO2 is a redox inactive metal oxide. Ni—V2O5—ZrO2/Al2O3 catalysts of the instant invention are preferred.

    摘要： The present invention relates to a trifunctional catalyst used in catalytic cracking device in petroleum refining industry and a method for preparing the same. The trifunctional catalyst of the invention comprises absorbent, cerium dioxide and vanadium pentoxide acting as oxidative catalyst and cerium oxyfluoride acting as structural promoter. The oxidative catalyst and structural promoter are dispersed over the absorbent. The absorbent is spinel-based composite oxides having a general formula of MgAl2-xFexO4.yMgO, where the x is 0.01-0.5 and y is 0.2-1.2. In the trifunctional catalyst, the raw material for forming the chemical compound containing rare-earth cerium is hamartite powder. The method for preparing the trifunctional catalyst of the invention is shown as follows: the components relating to the preparation of the finished product are dissolved or dispersed into liquid materials; then the trifunctional catalyst is obtained after the mixing, drying and calcining of such liquid materials. The trifunctional catalyst of the invention is used for highly efficient absorption and desorption of sulfoxides contained in the catalytic cracking flue gas regenerated in the process of petroleum refining, the combustion promoting of carbon monoxide and the reduction of nitrogen oxides. Furthermore, the method for preparing such trifunctional catalyst is featured for its lower cost.
