Abstract

A temperature-shifting two-stage fluidized bed reactor technology was used to convert propane and its intermediate products into aromatics. The first stage served for the aromatization of propane with a Ga/ZSM-5 catalyst at 570 °C. The second stage served for the alkylation of the intermediates of olefins at 300 °C. The increased yield of aromatics was attributed to the effective transformation of C-C olefins as well as due to the suppression of the hydrogen transfer effect of the olefins.

摘要

采用变温两段流化床反应器技术将丙烷及其中间产物转化为芳烃。第一阶段在570℃下用Ga/ZSM-5催化剂使丙烷芳构化。第二阶段在300℃下使烯烃中间体进行烷基化。芳烃产率的提高归因于C-C烯烃的有效转化以及烯烃氢转移效应的抑制。
