CO2 hydrogenation to methanol and DME

Methanol is a common feedstock considered as a building block in the chemical industry because of its versatility in the synthesis of several important chemicals such as chloromethane, acetic acid, methyl ferf-butyl ether (MTBE), alkyl halides, and formaldehyde [202, 203]. Methanol can be converted into DME which is 

Methanol is currently produced from Syngas as feedstock. The first industrial plant for methanol production was commissioned by BASF in 1923 using Syngas and operated at a high pressure of 20 MPa and 573 K using zinc oxide/chromium oxide catalysts [208]. 

Thermodynamically, a decrease in reaction temperature or an increase in reaction pressure can favor the synthesis of methanol. A reaction temperature higher than 513 K facilitates CO2 activation and, consequently, methanol formation [4,5,197].
