Injection of CO, into depleted natural gas reservoirs offers the potential to sequester carbon while simultaneously enhancing CH, recovey. Enhanced CH, recovery can partially offset the costs of CO, injection. With the goal of analyzing the feasibility of carbon sequestration with enhanced gas recovery (CSEGR), we are investigating the physical processes associated with injecting CO, into natur...

Two process models are used to convert carbon dioxide into methanol. These processes have been extended and improved using Aspen Plus simulator software. Both processes are found in the CO2 correction system. In this machine, the desired synthesis gas is produced in a flexible configuration. At the same time, the conversion of CO2 to hydrogen via a copper-based catalyst ha...

In this research. CO gas molthules were approached to single-wall carbon nanotube (SWNT) and (6,0) CNTsurface from carbon side and oxygen side in three states (top, bridge, centre) and two shapes ( erlica I.horizontal), then adsorption energies were calculated by B3TYP/6-310 B3LYPI3-216" and Hge3-210"methods after that they were compared m order to obtain the most stable adsorption state. OFT a...

Gasoline fuel vehicles cause emissions of airborne pollutants that are poisonous and have a deleterious effect on human health and the environment while natural gas fuels have less harmful effects on the environment and humans due to their greater environmental compatibility. The propose of this study is to investigate the concentration of CO, HC, O2 in the exhaust outlet of gas and diesel cars...

catalysts with the formula of laco(1+x)o(3+δ), where 0 ≤ x ≤ 1, were studied for oxidation of co and c2h6 in a synthetic exhaust gas, comprising 6.0 % co and 0.2 % c2h6 in ar. ethane was selected as a model for hydrocarbons in the exhaust gas. the performance of catalysts is correlated to their properties, particularly their redox in oxidizing and reducing atmospheres. xrd patterns show perovsk...

Interaction of pure and Vn-doped (8, 0), (12, 0) and (16, 0) boron nitride nanotubes with CO molecules was studied using B3LYP/6-311++G(d) theoretical level. Substituting V instead of B atoms, increased the reactivity of nanotube. From the results, the complex stability depends on the direction and the number of the CO molecules interacted with the nanotube. In this work, the quantum...
