Abstract: A catalyst for the dehydrogenation of alkanes to alkenes comprises a catalytically active material supported on a carrier, wherein the catalytically active material is a metallic sulfide (MeS) comprising Fe, Co, Ni, Cu, Mo or W or any combination of two or more metals selected from Pb, Sn, Zn, Fe, Co, Ni, Cu, Mo and W. The catalyst is regenerated in several steps. The dehydrogenation is carried out at a temperature between 450 and 650° C. and a pressure from 0.9 bar below ambient pressure to 5 bar above ambient pressure.

Abstract: A short channel ordered mesoporous carbon loaded indium cobalt sulfide and indium nickel sulfide ternary composite photocatalyst, and a preparation method and application thereof. The short channel ordered mesoporous carbon loaded indium cobalt sulfide and indium nickel sulfide ternary composite photocatalyst is prepared by mixing pretreated short channel mesoporous carbon with cobalt salt, nickel salt, indium salt and reducing agent with a hydrothermal reaction. The short channel ordered mesoporous carbon is obtained by calcining a short channel ordered mesoporous silica and a carbon source under the protection of nitrogen, wherein the short channel ordered mesoporous silica is prepared by carrying out reactions of sol-gel-hydrothermal-calcination sequentially using a mixture of a surfactant, a hydrochloric acid solution, ammonium fluoride and tetraethyl orthosilicate. The photocatalyst has strong adsorption and visible light catalytic activity on VOCs, and can effectively adsorb and decompose the enriched VOCs in situ on the surface of the catalyst.

Abstract: Alkyl alkanoates, e.g., methyl propionate, are made by a gas phase process comprising the step of contacting under carbonylation conditions an alkene (e.g., ethylene), carbon monoxide, an alkanol (e.g., methanol), and a solid sulfide-based metal catalyst (e.g., iron sulfide). The alkyl alkanoate can be converted in a second step to an alkyl ester of an aliphatic carboxylic acid, e.g., methyl methacrylate, through condensation with an aldehyde, e.g., formaldehyde.

Abstract: A method for preparing biomass graphene by using cellulose as a raw material includes preparing a catalyst solution, carrying out ionic coordination and high-temperature deoxidization on cellulose and a catalyst so as to obtain a precursor, carrying out thermal treatment and pre-carbonization, and carrying out acid treatment and drying to obtain the graphene. The graphene is uniform in morphology with a single-layer or multi-layer two-dimensional layered structure having a dimension of 0.5 μm to 2 μm, and an electric conductivity of 25000 S/m to 45000 S/m. The graphene can be applied to electrode materials of super capacitors and lithium ion batteries, and can also be added to resin and rubber as an additive so as to improve physical properties of the resin and the rubber.
