This study states that the recycling of carbon dioxide (CO2) cannot completely reduce the large concentrations of CO2 in the thermosphere, but it is indeed a functional process to produce modern chemicals. However, the process to hydrogenate CO2 with good selectivity and long term usage may require energy at high cost. Yuehui and Beller suggest that the intervention of more active and stable catalysts can lower the costs and increase the efficiency of the conversion of CO2 to methanol (CH3OH). Accordingly,

claim that using CO2 in chemical processes represents an alternative to reduce greenhouse gas emissions. The hydrogenation of CO2 can substitute natural gas by generating methane fuel as a viable source of energy. Using nickel base catalysts with a temperature range from 300° to 550° C at atmospheric pressure, this study concluded that the more the molar concentration of H2/CO2, the more effective is the conversion of CO2 to CH4 regardless of the temperature employed. Besides, from the catalytic activity, Marinoiu et al. determined that Ni/Al2O3-SiO2 is a potential catalyst as it proved easy, high, and stable conversion of CO2 to methane …show more content…

In this article, Jadhav et al. propose the chemical recycling of CO2 as a practical technique to generate methane, which has great demand in the chemical and energy industries. Economically, CO2 is inexpensive as it is obtained from any industrial or natural sources and human activities. The production of methane from the hydrogenation of CO2 can indeed substitute natural gas and petroleum oil since it provides an unrestricted and renewable source for fuels, hydrocarbons, and energy as well as the possibility to mitigate greenhouse gas emissions. Methanol synthesis by this process signifies an alternative form of energy and organic chemical production when fossil fuel sources are scarce. Indeed, Jadhav et al. conclude that the hydrogenation of CO2 is considered the most convenient technique economically after oil and gas in case appropriate conditions are used and later the most appropriate due to its inactive fossil fuel
