Methanol is an important primary chemical product, used as a chemical feedstock for production of a range of important industrial chemicals, primarily acetic acid, formaldehyde, methyl methacrylate and methyl tertiarybutyl ether (MTBE).
WhatsApp: +86 18203695377Methanol is a low carbon, hydrogen carrier fuel produced from high ash coal, agricultural residue, CO2 from thermal power plants and natural gas. It is a colourless liquid that boils at °C and solidifies at − °C . It forms explosive mixtures with air and burns with a nonluminous flame. It is completely miscible in water.

Under current trends, production could rise to
WhatsApp: +86 18203695377Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbonbased products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).
