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

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

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

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

Metallic supports play an important role as structured reactor internals. Due to their specific properties including enhanced heat and mass transport, high mechanical resistivity and elimination of local hot-spots, they are commonly used in gas exhaust ab... see more

CeO2 nanooctahedrons, nanorods, and nanocubes were prepared by the hydrothermal method and were then used as supports of Cu-based catalysts for the water-gas shift (WGS) reaction. The chemical and physical properties of these catalysts were characterized ... see more

In the context of sustainable production processes based on bio-derivable feedstocks, the hydrogenolysis of furfuryl alcohol gives access to two important diols. This work evaluates the performance of commercial copper catalysts in the aqueous phase hydro... see more

New ways to produce hydrogen, thought to be the ideal fuel, have been studied and aim at a not-pollutant fuel. Ethanol reform is based on a simple reaction with many advantages for various countries, such as Brazil, where ethanol is produced on a large sc... see more
