Activity Description
The process for producing ethylene glycol from coal-based methanol includes coal powder gasification, purification, methanol synthesis, distillation, olefin separation, olefin cracking to produce ethylene, ethylene oxidation to produce ethylene oxide, and ethylene oxide hydration to produce ethylene glycol.
Process Description
Ethylene glycol, also known as glycol or 1,2-ethanediol,简称EG, has the chemical formula (CH2OH)2 and is the simplest diol. It is a liquid under normal temperature and pressure conditions and is odorless. Ethylene glycol is miscible with water and acetone but has limited solubility in ethers. It is used as a solvent, antifreeze agent, and raw material for the synthesis of polyester.

Technology comment
The specific process for producing ethylene glycol from coal-based methanol includes: (1) gasification of coal powder to generate raw synthetic gas, which undergoes partial conversion via Co-Mo catalytic sulfur-resistant process, followed by cold methanol washing and sulfur recovery with liquid sulfur as a by-product; (2) purified synthetic gas is used to produce methanol through equipment such as Lurgi low-pressure methanol synthesis unit, methanol distillation columns, and hydrogen recovery units; the methanol is then converted to olefins via MTO process, and the olefins are cracked to produce ethylene; (3) ethylene is oxidized to form ethylene oxide, which is subsequently hydrated to produce ethylene glycol.
