Direct catalytic production of dimethyl ether from CO and CO2: A review

Dimethyl ether (DME) is a synthetically produced alternative fuel to diesel-based and could be used in ignition diesel engines due increasing energy demand. DME considered extremely clean transportation green because it has high cetane number (around 60), low boiling point (−25 °C), oxygen amount (35 wt%) which allow fast evaporation higher combustion quality (smoke-free operation 90% fewer NOx emissions) than other CO2-based fuels. can synthesized from various routes such as coal, petroleum, bio-based material (i.e., biomass bio-oil). CO2 prevent greenhouse gas emissions. This review aims summarize recent progress the field of innovative catalysts for direct synthesis dimethyl syngas (CO+H2) operating conditions. The problems this process have been raised based on yield selectivity ether. However, regardless how produced, estimated total capital costs industrial depend type reactor separation method.
