Selectivity and Performance of Ni-Mo/γ-Al2O3 Catalyst for Methanol Production with Reverse Water Gas Shift (RWGS) Reaction

چکیده
One of the main reactions that can be used to reduce greenhouse gases emissions is Reverse Water Gas Shift (RWGS) reaction. Through this reaction CO2 is converted to CO to produce beneficial chemicals such as methanol. In this paper Mo/Al2O3 catalyst was prepared and then promoted with Ni ions through impregnation method to produce Ni-Mo/Al2O3 catalyst. The structures of the catalysts were studied using XRD, XRF and TEM techniques. Activity, selectivity and stability of both catalysts were investigated in a batch reactor and the results indicate that addition of Ni promoter to Mo/Al2O3 catalyst increased its activity and CO selectivity. Ni-Mo/Al2O3 showed acceptable catalytic stability during RWGS reaction. As a whole Ni-Mo/Al2O3 can be a suitable candidate for methanol production process from CO2 using RWGS reaction. [A.

متن کاملCO2 Reforming of Coke Oven Gas Over a Ni/γAl2O3 Catalyst to Produce Syngas for Methanol Synthesis
The CO2 reforming of coke oven gases (COG) was carried out over a Ni/γAl2O3 catalyst in order to obtain a suitable syngas for methanol synthesis. The influence of different operating conditions, such as temperature and volumetric hourly space velocity (VHSV), was studied. It was found that the H2 present in the feed gas promotes the Reverse Water Gas Shift reaction (RWGS), which produces water....

The CO2 reforming of coke oven gas for the production of synthesis gas has been studied over an activated carbon, an in-lab prepared Ni/Al2O3 catalyst and physical mixtures of both materials in different proportions (AC+Ni) at 800 oC. It was found that there are two possible coexisting reaction pathways: the direct dry reforming of methane (decomposition of methane followed by gasification of t...

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 ...
