Methanoltogasoline process2 In the MTG process, the conversion of methanol to hydrocarbons and water is virtually complete and essentially stoichiometric. The reaction is exothermic with a heat of reaction of approximately MJ/kg of methanol with an adiabatic temperature rise of approximately 600 ˚C. In the fixed bed process

The coalbased process releases about kg CO 2 /kg methanol, and the natural gasbased process releases about kg CO 2 /kg methanol (Galindo Cifre and Badr, 2007, Rivarolo et al., 2016). Production of methanol from renewable sources reduces the intensity of fossil fuels as the main feed and also helps in mitigating CO 2 emissions ...
