The invention relates to a novel catalyst for hydrogenation for hydrogenating at least one of dicarboxylic acid or its acid anhydride. The catalyst for hydrogenation according to a first embodiment is obtained by supporting at least one of palladium or platinum, and cobalt on a carrier, and subjecting the resulting carrier to a reduction treatment at 400 K or higher. The catalyst for hydrogenation according to a second embodiment is obtained by supporting at least one of palladium or platinum, and molybdenum on a carrier, and subjecting the resulting carrier to a reduction treatment at 500 K or higher.

Catalysts for the hydrogenolysis of butane are described. A supported catalyst for hydrogenolysis of butane to ethane can include a support and a catalytic crystalline bimetallic composition that can include a molybdenum-iridium (Mo—Ir) crystalline composition attached to the support. The supported catalyst has a BET specific surface area of at least 100 m.sup.2/g, preferably 100 m.sup.2/g to 500 m.sup.2/g. Method of use and methods of making the catalyst are also described.

An object of the present invention is to provide platinum-tungsten solid solution particles that can be suitably used for catalyst applications and others. Another object is to provide a catalyst with higher catalytic activity than when platinum is used alone. Disclosed are platinum-tungsten solid solution particles comprising platinum and tungsten in solid solution at an atomic level. Also disclosed is a catalyst comprising the platinum-tungsten solid solution particles.

Methods and a reactor system for producing acetic acid in a selective oxidation (SO) reactor are provided. An example method includes providing a fresh feed stream to the SO reactor, wherein the fresh feed stream includes a methane feed stream, a carbon dioxide feed stream, and a steam feed stream. Acetic acid is formed in the SO reactor. An acetic acid product stream is separated from a reactor effluent stream in a scrubber. A recycle gas stream is obtained from the scrubber. At least a portion of the recycle gas stream is combined into the fresh feed stream to the SO reactor.

A catalyst for oxidative dehydrogenation (ODH) of ethane with an empirical formula Mo—V—Te—Nb—Pd—O produced using a process comprising impregnation of the Pd component on the surface of the catalyst following a calcination step using a Pd compound free of halogens. The resulting catalyst can be used in both diluted and undiluted ODH processes and shows higher than expected activity without any loss of selectivity.

In a method, device, catalyst and a method for producing a catalyst for the catalytic conversion of a substance mixture containing glycerol to propanol in a fixed-bed reactor, substrates of the catalyst have inorganic materials and/or metal oxides. The substrates have a pore diameter at the surface of between 10 and 25 angstroms, preferably between 12 and 20 angstroms, particularly preferably 15 angstroms.

The present invention relates to carbon nanotubes having a pore volume of 0.94 cm.sup.3/g or more, and being an entangled type, a method of manufacturing the same, and a positive electrode for a primary battery which comprises the same.
