摘要:

与采用低温费托合成主产油品技术相比,产品更为多元化和高值化的高温费托合成技术在目前市场环境下显示出非常明显的优势。本文综述了高温费托合成技术的发展历程及其最新进展,重点介绍了高温费托合成过程中的核心问题,主要包括高温费托合成工艺、固定流化床反应器、费托合成催化剂;介绍了高温费托合成产物分布与特性,讨论了高温费托合成产物的加工路线,并对高温费托合成煤间接液化的工业应用前景和产业化方向进行了展望。结果表明:高温费托合成技术具有产物附加值高、兼顾油品和化学品、技术发展成熟等优势,产物中轻组分含量高、碳数分布较窄、高附加值的α-烯烃含量高;精细化、高端化、差异化加工是实现高温费托合成产物高值化利用的关键。

Abstract:

Compared with low temperature Fischer-Tropsch synthesis technology with oil as main product,high temperature Fischer-Tropsch technology which produces the more diversified and high-value products, has obvious advantages during the current market environment.In this paper,the development and recent advance of high temperature Fischer-Tropsch synthesis technology are reviewed. The critical issues, including high temperature Fischer-Tropsch synthesis process, fixed-fluidized bed reactor and catalyst of high temperature Fischer-Tropsch synthesis are also discussed. The product distribution and characteristics of high temperature Fischer-Tropsch synthesis are introduced. The products processing route is also discussed, and the industrial application prospect and industrialization direction are prospected. The analysis shows that the high-temperature Fischer-Tropsch synthesis technology has the advantages of high added value of products, consideration of oil products and chemicals, and mature technology. The products have high light component content, narrow carbon number distribution and high added value α-olefin content. Fine, high-end, and differential processing are the key to achieving high-value utilization of high-temperature Fischer-Tropsch synthesis products.

Key words: high temperature Fischer-Tropsch synthesis, indirect coal liquefaction, α-alkene, fixed-fluidized bed reactor, catalyst
