Simulation of methanol synthesis by hydrogenation of carbon dioxide recovered from combustion gases of Fluid Catalytic Cracking Unit of Abadan Refinery
Refineries produce about four percent of the global carbon dioxide emissions, close to one billion tons per year. Globally, the refining sector is the third largest producer of carbon dioxide after the electricity generation and cement industry.This greenhouse gases is a major cause of global warming and climate change and is a serious threat to human health and the environment. One way to redu...
متن کاملPreparation of Cu/ZnO and Cu/ZnO/Al2O3 Methanol Catalysts by Gas-Phase Loading of Mesoporous Silica: Aiming at Superior Catalytic Activity by Molecular Control of their Microstructure
Copper-based catalysts (Cu/ZnO and Cu/ZnO/Al2O3) are the basis of the industrial methanol synthesis and methanol oxidation and are important components of fuel cell technology. For the preparation of these catalysts, metal–organic chemical vapor deposition (MOCVD) technique has proven its potential. Furthermore, studying synergistic metal–support interactions, strategies can be developed to gai...
متن کاملComment on "Active sites for CO2 hydrogenation to methanol on Cu/ZnO catalysts".
Kattel et al (Reports, 24 March 2017, p. 1296) report that a zinc on copper (Zn/Cu) surface undergoes oxidation to zinc oxide/copper (ZnO/Cu) during carbon dioxide (CO2) hydrogenation to methanol and conclude that the Cu-ZnO interface is the active site for methanol synthesis. Similar experiments conducted two decades ago by Fujitani and Nakamura et al demonstrated that Zn is attached to format...
متن کاملResponse to Comment on "Active sites for CO2 hydrogenation to methanol on Cu/ZnO catalysts".
In their Comment on the our recent Report, Nakamura et al argue that our x-ray photoelectron spectroscopy (XPS) analysis was affected by the presence of formate species on the catalyst surface. This argument is not valid because the reactant gases were evacuated at temperatures from 525 to 575 kelvin, conditions under which formate is not stable on the catalyst surface. An analysis of the XPS r...
متن کاملCatalytic hydrogenation of carbon dioxide using Ir(III)-pincer complexes.
Catalytic hydrogenation of carbon dioxide in aqueous potassium hydroxide was performed using a newly synthesized isopropyl-substituted PNP-pincer iridium trihydride complex as a catalyst. Potassium formate was obtained with turnover numbers up to 3,500,000 and a turnover frequency of 150,000 h(-1), both of which are the highest values reported to date.
