煤制芳烃产业化进展及制约因素分析

Study on Progress and Constraint in Commercialization of Methanol to Aromatics Process

芳烃是重要的基础有机化工原料,约95%的芳烃来自石油路线。根据我国"富煤,少油,少气"的独特能源禀赋,建立煤制芳烃产业化技术,一方面可使芳烃来源多元化,形成石油制芳烃的有效补充,一定程度上降低我国石油对外依存度;另一方面促进传统煤化工向清洁、绿色的现代煤化工转型。本文主要对煤制芳烃的产业化现状及制约产业化的主要因素进行研究,并提出对应的产业化建议,包括加强技术攻关和技术创新,降低成本、合理选址,因地制宜以及全产业链布局,可为发展煤制芳烃产业提供决策参考。

Aromatics are important basic chemical raw materials, but with about 95 percent derived from crude oil. Given China＇s energy resource structure ＂rich in coal but short of oil and gas＂ and rising dependence on imported crude oil, coal-based methanol to aromatics （MTA） technology not only can diversify the sources of aromatics to help supplement the crude oil-based aromatics and ease our reliance a bit on foreign oil, but also can promote the transformation of traditional coal chemical industry into clean, green and modern one. Therefore, this article mainly studies on the status and constraints in commercialization of coal-based methanol to aromatics process, and puts forward corresponding suggestions for related decision-making reference, including more efforts to make technological breakthrough and innovation and thus to lower the cost, project site selection in line with local conditions, and overall arrangement covering the industry chain from coal to methanol, aromatics and end products.
