Methanol is commercially produced from natural gas
through a syngas route. Steam methane reforming produces a
mixture of CO, CO2and H2according to Eqs.(1) and (2). Syngas
is then converted to methanol in the ranges of temperature,
250–300
◦
C, and pressure, 5–10 MPa, using CuO/ZnO/Al2O3catalyst (see Eq.(3))
