据报道,一家美国公司研发出使用二氧化碳电化法,结合水等氢源生产乙二醇的新技术,预计可以将乙二醇生产成本降低至125美元/吨,同时还具备环保优势。目前,中国企业生产一吨煤制乙二醇工艺成本在4500元/吨左右。照此计 It is reported that a U.S. company has developed a new technology that uses carbon dioxide electrochemical method, combined with hydrogen source such as water to produce ethylene glycol. It is estimated that the production cost of ethylene glycol can be reduced to 125 US dollars / ton, while also having environmental advantages. At present, the cost of producing one ton of coal-to-ethylene glycol by Chinese enterprises is around 4,500 yuan / ton. According to this plan
