摘要:

目前我国甲醇产能接近9800万吨、产量8000万吨,表观消费量约占世界总量的60%,自给率达90%以上,但以煤为主天然气和焦炉气为辅的原料格局导致甲醇生产每年产生2亿吨CO2排放。文章指出:在碳中和背景下,随着以电力领域为代表的烟气CO2捕集工作的深入开展、绿电装机规模的不断增加,将有越来越多的CO2和绿电以产品形式存在,捕集1t CO2的综合成本达到300元左右。在该成本边界下,如不能将捕集获得的CO2进行资源化利用带来效益,将会对双碳目标的达成带来不利影响,因此如何对CO2进行转化利用成为研究热点,将CO2加氢合成绿色甲醇则是一个很好的解决方案,并且相关研究和工业开发也逐渐掀起热潮。本文从政策驱动、工艺优势、降碳效应、绿电及CO2转化消纳、市场需求、甲醇产业升级6个方面进行了分析,认为发展绿色甲醇是实现碳中和目标重要且必要的举措之一。

Abstract:

At present, the methanol production capacity is close to 98 million tons and the output is 80million tons. The apparent consumption of methanol accounts for about 60% of the world total, and the self-sufficiency rate is more than 90%. However, the raw material pattern of methanol production, supplemented by natural gas and coke oven gas, leads to the annual CO2 emission of 200 million tons. Under the background of carbon neutrality, with the in-depth development of flue gas CO2 capture represented by the power field and the continuous increase of the installed scale of green electricity, more and more CO2 and green electricity will exist in the form of products. The comprehensive cost of capturing a ton of CO2 reaches about 300 yuan. Under this cost boundary, if the CO2 captured cannot be recycled to bring benefits. Therefore, how to convert and utilize CO2 has become a research hotspot, and hydrogenation of CO2 to green methanol is a good solution. Moreover, relevant research and industrial development have also gradually set off a boom. In this paper, six aspects of policy driving, technological advantages, carbon reduction effect, green electricity and CO2 conversion consumption, market demand, methanol industry upgrading were analyzed, and the development of green methanol was considered to be one of the important and necessary measures to achieve the goal of carbon neutrality.

Key words: carbon reduction, carbon reduction, green methanol, development, necessity
