Performance of Co-Mo/Al2O3 Nano Catalyst for CAMERE Process in a Batch Reactor

The amount of carbon dioxide in the atmosphere is increasing continuously. Its accumulation in the air is one of the major causes of global warming and the change at equilibrium condition of weather and the environment. Utilization of carbon dioxide and other greenhouse gases to produce useful chemicals could be a suitable solution to this problem. CO2 is not just a greenhouse gas, but also an important source of carbon for producing organic chemicals, materials, carbohydrates, and fuels such as methanol, carboxylic acids and ethylene.1–6 It is important to note that the amount of CO2 emitted as the concentrated CO2–rich flue gases from electric power plants and effluent gases from industrial manufacturing plants have become much higher than the amount of carbon used for making most chemicals, organic materials and liquid transportation fuels.7 The conversion of CO2 into chemical resources has been attempted by several methods to mitigate the greenhouse effects.8,9 The RWGS can be used in some cases for control of CO2 emission. In this reaction CO2 is used to produce CO. The products of this reaction can be used in production of clean fuels such as methanol and dimethyl carbonate (DMC). The catalytic hydrogenation of CO2 to form methanol is one of the efficient processes being able to treat a large quantity of CO2 and the produced methanol can be consumed in the conventional chemical industry.10,11 In recent years, most of the authors 12–15 considered carbon dioxide to be the direct source of methanol production but the yield of methanol produced from CO2 is lower than CO. 16 The reverse water gas shift (RWGS) reaction,
