Methanol is usually produced with high selectivity, although minor amounts of side products are found. It should be noted that the hydrogen produced in the industry is considered as a chemical product and the commercial sale of hydrogen is less than 10% of its production in the world, which means that 90% of the hydrogen produced is consumed at the production site. The synthesis is usually conducted at 200-300 C and 3.5-10 MPa. high pressure. Although the majority of methanol synthesis is based on natural gas as feedstock, coal-derived syngas is also used; coal/solid feedstocks are used to make 9% of the worldwide output of methanol (Gasification,Higman C., Van der Burgt M., 2003).
