由C_4～C_8轻烃制取三苯

Preparation of BTX from C4C8 Light Hydrocarbons

以油田生产的轻烃（Ｃ４～Ｃ８）为原料，在Ｇａ／Ｚｎ／ＺＳＭ－５催化剂上芳构化，并给出催化剂在１００ｍｌ（催化剂填装量）试验装置上进行稳定性考核的１０００ｈ试验结果。在反应温度为５５０℃、ＷＨＳＶ为０５ｈ－１、反应转化率为９６％时，芳烃质量收率可达５５５１％。在此基础上，讨论了轻烃（Ｃ４～Ｃ８）制取三苯的３×１０４ｔ／ａ工业中试装置的设计及工艺流程。

This article describes the aromatization with Ga/Zn/ZSM-5 of light hydrocarbons (C4C8 alkanes).Catalyst stability test results are obtained by running the test in a 100 ml unit(cat.volume),for 1 000 h at 550 and WHSV 05 h-1.The conversion is 96%,and aromatics yield is 5551%(m).The process and design of an industrial BTX pilot plant with a capacity of 3104 t/a is discussed.
