The hydrogen production from ammonia decomposition on commercial 5 wt.% Ru/C (C: activated carbon) catalyst with different cesium (Cs) loadings at lower temperatures of 325–400 °C in the fixed-bed reactor was experimentally investigated. Based parameters used this work, results showed that conversion 350 is increased increasing Cs/Ru molar ratio, and it reaches its maximum value ratio 4.5. Afte...

Nanoparticles of 35 individual metals as well as their binary combinations were synthesized using High Throughput pulsed laser ablation (PLA), and collected on Al(2)O(3), CeO(2), SiO(2), TiO(2), and ZrO(2) pellets. These materials were then screened for their catalytic activities and selectivities for the partial oxidation of propylene, in particular for propylene oxide (PO), using array channe...

The synthesis of selected state-of-the-art catalysts providing high performances in the oxidative coupling of methane (OCM) with O2 was reproduced according to the respective methods reported in literature. A reference material with identical stochiometric composition was further synthesized by applying the cellulose templating (CT) method. This method increases the surface area and affects the...

The complete 154-kbp linear double-stranded genomic DNA sequence of herpes simplex virus 2 (HSV-2), consisting of two extended regions of unique sequences bounded by a pair of inverted repeat elements, was published in 1998 and since then has been widely employed in a wide range of studies. Throughout the HSV-2 genome are scattered 150 microsatellites (also referred to as short tandem repeats) ...

In this study, Ag-Cu-Ce/TiO2 catalyst was produced by using impregnation method for hydrocarbon-selective catalytic reduction (HC-SCR) system. system, as a reducing agent ethyl alcohol and urea solution mixture used. The NOx conversion efficiency of the system with synthesized analyzed. Chemical structural properties used were examined SEM, BET XRD analyzes. SCR test experiments conducted in di...

Zirconia (ZrO2) nanoparticles were synthesized by solution combustion using urea as an organic fuel. Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), transmission electron microscopy (TEM), UV-vis and Fourier transform infrared (FTIR) measurements were performed in order to characterize the catalyst. The calculated crystallite size of ZrO2, calculated w...

Catalytic elimination of formaldehyde (HCHO) was investigated over Cu-Al2O3 catalyst at room temperature. The results indicated that no oxidation of HCHO into CO2 occurs at room temperature, but the adsorption of HCHO occurs on the catalyst surface. With the increase of gas hourly space velocity (GHSV) and inlet HCHO concentration, the time to reach saturation was shortened proportionally. The ...

The oxidation of ammonia to nitrogen by selective catalytic oxidation (NH3-SCO) over a bimetallic CuO/CeO2 nanoparticle catalyst at temperatures between 423 and 673K. A bimetallic CuO/CeO2 nanoparticle catalyst was prepared by co-precipitation method at molar ratio of 6:4. This study also considers how the concentration of influent NH3 (C0 = 800 ppm), the space velocity (GHSV = 92000/hr), the r...

Due to its excellent conductivity, good thermal stability and large specific surface area, carbon nano-tubes (CNTs) were selected as support to prepare a Re-based catalyst for dimethyl ether (DME) direct oxidation to polyoxymethylene dimethyl ethers (DMMx). The catalyst performance was tested in a continuous flow type fixed-bed reactor. H3PW12O40 (PW12) was used to modify Re/CNTs to improve its...

Biogas is mainly composed of CH4 and CO2, so it used as an alternative energy to with high density by separating removing CO2 from biogas. In addition, can be utilized producing synthesis gas (CO H2) through thermal decomposition biogas or synthesizing methanation CO2. The technique a method that improve the concentration without separation. This study aims produce more efficient methane over N...
