Cu/ZnO catalysts promoted with Mn, Nb and Zr, in a 1:1:1 ration, supported on Al2O3 (CZMNZA) SBA-15 (CZMNZS) were synthesized using an impregnation method. The catalytic performance of methanol synthesis from CO2 hydrogenation was investigated fixed-bed reactor at 250 °C, 22.5 bar, GHSV 10,800 mL/g·h H2/CO2 ratio 3. CZMNZA catalyst resulted higher conversion MeOH selectivity 7.22% 32.10%, respe...

Commercial cerium–zirconium oxide supports (Ce0.5Zr0.5O2, Ce0.75Zr0.25O2, and Ce0.4Zr0.5Y0.05La0.05O2) were used to prepare Ru/CeZrOx catalysts. According the XRD IR spectroscopy data, consist of ceria-based substitutional solid solutions. The specific surface areas catalysts are similar range from 71–89 m2/g. As shown by TEM methods, size support particles equals 6–11 nm. ruthenium does not ex...

a series of x(co, mn)/tio2 catalysts (x=2–12wt.%) containing 25%co and 75%mn were prepared by the co-impregnation method. all prepared catalysts have been tested in fischer-tropsch synthesis for production of c2-c4 olefins. it was found that the catalyst containing 8wt.%(co,mn)/tio2 is an optimal catalyst for production of c2-c4 olefins. the effect of operation conditions such as the h2/co mola...

The non-oxidative dehydrogenation of methanol to formaldehyde is considered a dream reaction compared with the classical oxidative route, because valuable coupled product hydrogen formed instead water, and produced anhydrous highly suitable for further synthesis oxygenated synthetic fuels. This study reports on high catalytic performance pure β-Ga2O3 in this at temperatures between 500 °C 650 °...

The present study focuses on the catalytic conversion of syngas (CO + H 2 ) through Fischer–Tropsch (FT) route using two identically prepared 0.1 wt.% palladium promoted Mesoporous Alumina (MA) and SBA–15 supported Co (15 wt.%) catalysts. activity is performed in a fixed bed tubular reactor at temperature 220 °C pressure 30 bar with /CO ratio ~2 having Gas Hourly Space Velocity (GHSV) 500 h −1 ...

The present work deals with Low Temperature CO Oxidation for Fire Escape Mask development. Building and property fires often contain as high as 3600 ppm of carbon monoxide. The goal of this work is to develop a thin layer catalyst (1-5 mm) capable of reducing carbon monoxide from inlet concentrations of 3600 ppm to less than 400 ppm for at least 15 – 60 minutes while meeting other CBRN (chemica...

Catalytic oxidation of formaldehyde (HCHO) to CO2 at ambient conditions is of great interest for indoor HCHO purification. Here, we report that sodium-doped Pd/TiO2 is a highly effective catalyst for the catalytic oxidation of HCHO at room temperature. It was observed that Na doping has a dramatic promotion effect on the Pd/TiO2 catalyst and that nearly 100% HCHO conversion could be achieved ov...

The aim of this work is to study the pollutants removal efficiency together with the catalyst activation temperature when a Diesel Oxidation Catalyst (DOC) is placed downstream to a multi-plans Dielectric Barrier Discharge (DBD) reactor. In order to simulate Diesel engine exhaust, synthetic gas mixtures containing N2, O2, H2O, CO2, CO, NO, and hydrocarbons (HCs) at controlled concentrations cou...

Nano-sized iron-based catalyst was prepared by the micro-emulsion method. The composition of the final nano-sized iron catalyst, in term of the atomic ratio contains: 100Fe/4Cu/2Ce. Experimental techniques of XRD, BET, TEM and TPR were used to study the phase, structure and morphology of the catalyst. Fischer-Tropsch Synthesis (FTS) reaction test was performed in a fixed bed reactor at pressure...
