Disclosed are a catalyst including copper (Cu) particles having specific properties as an active metal dispersed and supported on an alumina support, a method of preparing the same, and a method of hydrogenating furan-based compounds such as 5-(hydroxymethyl)furfural (HMF) derived from biomass with a high selective conversion and high efficiency using the catalyst.

The invention relates to an improved catalyst based on a tableted molded catalyst body, containing a metal-containing mixture, containing copper, zinc, and aluminum, with calcium aluminate as a binder material with a weight fraction of calcium aluminate in the range of 1.0% to 30.0%, for synthesizing methanol from synthesis gas. The invention further relates to the production of the catalyst and to the use of the catalyst in the synthesis of methanol from synthesis gas.

The present disclosure provides a catalyst for dehydrogenation of liquid organic hydrogen carriers, including: a support; and a catalytically active ingredient on the support, wherein the support has a pore size of 10 nm or more.

A direct decomposition device for hydrocarbons for directly decomposing hydrocarbons into carbon and hydrogen includes a rector containing a catalyst including a plurality of metal particles with an iron purity of 86% or more. The reactor is configured to be supplied with a raw material gas containing hydrocarbons.

An aromatization catalyst and preparation process and use thereof is set forth. The catalyst comprises an inorganic oxide and a modified Ga-ZSM-5 zeolite, which comprises a modified ZSM-5 zeolite with a hierarchical macro-meso-microporosity and gallium deposited in channels of and/or on surfaces of the modified ZSM-5 zeolite. The hierarchical porosity of the modified ZSM-5 zeolite in the catalyst can reduce diffusion resistance of products during the aromatization reaction, thereby retarding carbon depositing rate and substantially improving catalytic activity, aromatic hydrocarbon selectivity, stability and lifetime of the catalyst. When being used in aromatization of propane, the catalyst exhibits a high stability, a lifetime of more than 320 hours, and a selectivity to aromatic hydrocarbons of up to 73.3 wt. %.

A methanation catalyst for the methanation of carbon monoxide and/or carbon dioxide is disclosed that provides high selectivity and stability, and additionally shows improved activity compared with prior catalysts. The methanation catalyst for the methanation of carbon monoxide and/or carbon dioxide comprises aluminum oxide, a Ni active mass, and Mn, wherein the Ni/Mn molar ratio in the catalyst is 3.0 to 10.0.

The invention relates to novel methods for preparing N-methyl-p-toluidine for the use thereof as additive for aviation fuel, and to specific catalysts for these methods.

A nickel diatomaceous earth catalyst having a weight loss rate measured by hydrogen-TG at 400 to 600 C. of 0.05 to 2.0%.
