Abstract

Techniques for capturing CO₂ to create valuable chemicals and fuel can address enough of the environmental problems caused by the use of fossil fuels. The rate of methanol synthesis at the metal-oxide interface and the swift conversion of methanol to Al₂O₃ at acid sites had an impact on the production of DME.The synthesis of the intermediate is highly dependent on the texture, structure, and surface, based to an in-situ/operando Fourier Transform Infrared (FTIR) spectroscopy analysis performed under the reaction conditions (0.9 MPaG, 220-260°C).Formate species are created during the synthesis of methanol, depending on the conditions of the process. Technically speaking, the best conditions for converting CO₂ and producing DME yield are a reaction temperature of less than 260°C and a reaction pressure of 0.9 MPaG.
