摘要： Disclosed is an electrocatalyst for fuel cells, in which a porous carbon material including pores having a diameter smaller than a kinetic diameter of carbon monoxide is used as a support body and contact probability between an activated metal and carbon monoxide is decreased, thereby preventing fuel cell performance from being degraded by carbon monoxide. The electrocatalyst is obtained by adsorbing 10-80 parts by weight of an activated metal to 20-90 parts by weight of a porous support body, characterized in that the porous support body has a total surface area of 200-2,500 m2/g including an outer surface thereof and an inner surface of pores thereof, and has a plurality of pores penetrating into an interior of the support body with an average diameter of 2-15 nm and a total volume of 0.4-2.0 m3/g, and the activated metal is alloyed with 20-95 at % of platinum and 5-80 at % of one metal selected from among Ru, Sn, Os, Rh, Ir, Pd, V, Cr, Co, Ni, Fe and Mn. As for such an electrocatalyst, carbon monoxide does not fundamentally come in contact with the activated metal adsorbed to the inner surface of the pores of the support body, thereby minimizing degradation of fuel cell performance, thus overcoming fuel-feeding problems.

摘要： A catalyst manufacturing process includes heat treating an intermediate catalyst composition that includes catalyst nanoparticles having catalyst atoms in a non-zero oxidation state bonded to a dispersing/anchoring agent. The catalyst nanoparticles are formed using a dispersing agent having at least one functional group selected from the group of a hydroxyl, a carboxyl, a carbonyl, an amide, an amine, a thiol, a sulfonic acid, sulfonyl halide, an acyl halide, an organometallic complex, and combinations of these. The dispersing agent can be used to form single- or multicomponent supported nanocatalysts. The dispersing agent also acts as an anchoring agent to firmly bond the nanocatalyst to a support. Performing the heat treating process in an inert or oxidative environment to maintain the catalyst atoms in a non-zero oxidation helps maintains a stronger bonding interaction between the dispersing agent and the catalyst atoms. This, in turn, increases the dispersion and/or distribution of catalyst components throughout the supported catalyst.

摘要： A process and catalyst for the partial oxidation of paraffinic hydrocarbons, such as ethane, propane, naphtha, and natural gas condensates, to olefins, such as ethylene and propylene. The process involves contacting a paraffinic hydrocarbon with oxygen in the presence of hydrogen and a catalyst under autothermal process conditions. Preheating the feed decreases oxygen consumption and increases the net hydrogen balance. The catalyst comprises a Group 8B metal, preferably, a platinum group metal, and at least one promoter selected from Groups 1B, 6B, 3A, 4A, and 5A, optionally supported on a catalytic support, such as magnesia or alumina. In preferred embodiments, the support is pretreated with a support modifier selected from Groups 1A, 2A, 3B, 4B, 5B, 6B, 1B, 3A, 4A, 5A, the rare earth lanthanides, and the actinides. A modified fluidized bed reactor is disclosed for the process.
