摘要
介绍了提高煤质乙二醇紫外透光率的方法,主要有物理方法和化学方法。河南能源化工集团采用催化加氢和树脂吸附联用的方法提高煤质乙二醇的紫外透光率,使煤质乙二醇产品达到了聚酯级产品标准。
The methods to improve UV transmittance of coal-based ethylene glycol are introduced,including physical adsorption and chemical treatment methods. The factors influencing UV transmittances of coal-based ethylene glycol include aldehydes,ketones,carboxylic acids and other trace compounds.Henan Energy and Chemical Industry Group Co.,Ltd.employs a method combining catalytic hydrogenation with resin adsorption,which make ethylene glycol reach the standard for polyester grade successfully.
