Methanol steam reforming is a promising technology for producing hydrogen for onboard fuel cell applications. The methanol conversion rate and the contents of hydrogen, carbon monoxide and carbon dioxide in the reformate, significantly depend on the refor... see more

In this work, we are interested in finding new catalysts for catecholase, whose principle is based on the oxidation reaction of catechol to o-quinone. We approached the synthesis of the threes tripod ligands based on pyrazole in a condensation reaction an... see more

The catalytic activities of Cu/ZrO2_CaO catalysts were investigated on CO2 hydrogenation. The CO2 hydrogenations were carried out over combination of calcium oxide and Cu/ZrO2 catalyst. Two calcination temperatures were chosen at 300 and 650oC according t... see more

Fatty alcohol (FAOH) can be produced by hydrogenating of fatty acid methyl ester (FAME) using the copper-based catalyst. Copper-Chrom (Cu-Cr) is the best catalyst for high-pressure reaction condition, which is copper (Cu) as the main active component and ... see more

This study investigates the potential of bimetal impregnated catalysts supported on activated carbon derived from biomass for Selective Catalytic Reduction (SCR) of Nitrogen Oxides (NOx) with ammonia (NH3). The bimetal catalysts, Copper-Manganese (Cu-Mn) ... see more

The use of immobilized catalysts based on complexes of transition metals in the oxidation process has great importance nowadays. Polymeric metal complex catalysts for petrochemical processes taking place in the liquid phase are environmentally effective a... see more

In this work we obtained a polymer-metal complex by mixing aqueous solution of copper(II) acetate with PVA at a certain ratio, pH of the solution and temperature. The composition of the complex compound was determined by potentiometric and conductometric ... see more

Cu/Nb2O5 catalysts were modified by the incorporation of MgO or K2O (support acidity reducer) and Ni (a facilitator of the bond break C-C) to be used in the ethanol reforming in bench-scale unit with catalytic bed of 7 g at 573 K, varying the space veloci... see more

Polioxide granulated catalysts based on transition and rare earth metals for oxidative conversion of xylene by oxygen have been investigated. It was defined the effect of the composition and concentration of the active phase of oxide catalysts: Cu-Mn-Ln; ... see more
