摘　　要：与采用低温费托合成生产柴油的传统煤制油技术相比,产品更为多元化和高值化的高温费托合成技术在低原油价格时期显示出非常明显的优势。本文介绍了高温费托合成现有的技术进展,包括南非Sasol公司的高温铁基循环流化床和固定流化床技术与兖矿集团的高温铁基固定流化床技术。总结分析了熔融铁、沉淀铁、负载铁催化剂以及温度、气体组成与压力、流化状态等工艺条件对高温费托合成产物分布的影响。结合高温费托合成的典型产物分布,讨论了提高烯烃等目标产品的方法,并对高温费托合成未来的主要发展方向进行了展望。Compared with low-temperature Fischer-Tropsch synthesis technology with diesel asmain product, high-temperature Fischer-Tropsch technology which produce the more diversifiedand high-value products, has obvious advantages during low crude oil price period. In this paper,the existing technical progresses of high temperature Fischer-Tropsch synthesis were reviewed,including Sasol＇ s high-temperature iron-based circulating fluidized bed and fixed fluidized bedtechnology and Yankuang Group＇s high-temperature iron-based fixed fluidized bed technology.The effects of the fusion iron, precipitated iron, supported iron catalyst and process conditionssuch as temperature, gas composition, pressure and fluidization state on the distribution of FTSproducts were analyzed and summarized. Combined with the typical product distribution, themethod of improving the target products such as olefins was discussed, and the futuredevelopment direction of high-temperature Fischer-Tropsch synthesis was prospected.
