Methanol (methylol) production method

Wood alcohol or methanol is produced from petroleum product (synthesis gas) through hydrogenation of CO and CO2 and reverse gas-water shift reaction, doping of manganese catalyst to Cu/Zn/Zr can increase its production rate. Catalysts that have the ability to work at low temperatures, such as copper, are used for efficient methanol production. Natural gas is the most economical and widely used raw material for methanol production. However, other raw materials such as coal are used as feedstock for methanol production, especially in China. Methanol was previously produced by the destructive distillation of wood. The modern method of methanol preparation is based on the direct combination of carbon monoxide gas and hydrogen in the presence of a catalyst.

In fact, in general, the production of methanol includes seven stages:

• Feed preparation
• Synthesis gas production
• Synthesis gas density
• Methanol synthesis
• Methanol purification
• Steam and condensate system
• Storage and loading

Applications of methanol (methylol)

Methanol derivatives are used to make many compounds, such as paints, resins, medicines, perfumes, as fixatives in the laboratory, solvents, antifreezes, as coolants in refrigerators, explosives, plastics, laminates, various varnishes, glue industry and Home use

Methanol is used on a limited basis to fuel internal combustion engines, primarily because it is not nearly as flammable as gasoline and produces only one-eighth as much heat.

Methanol In some wastewater treatment plants, a small amount of methanol is added to the wastewater to provide a carbon food source for disinfecting bacteria, which convert nitrates to nitrogen to reduce from sensitive aquifer treatment.

Due to the foreseeable shortage of energy sources in the future, the direct consumption of industrial alcohol as a clean fuel or in the production of hydrogen for fuel cells has received much attention.

Methanol is also used in the production of dimethyl ether (DME) and as a substitute for gas oil.
