EO/EG催化剂国产化以及在壳牌合成工艺上的应用

Localization of EO/EG Catalyst and Application in Shell Process

文章围绕乙烯在银催化剂作用下氧化生成环氧乙烷的反应,介绍了壳牌乙二醇转化MASTER工艺和OMEGA工艺,以及壳牌催化剂特点、Walter Tosto反应器及工作条件。介绍了国产替代催化剂乙二醇YS-9010催化剂,及其在壳牌乙二醇转化工艺上的运营测试。测试结果显示,国产乙二醇催化剂替代壳牌催化剂后,装置整体运行工况良好,而且采购成本、技术服务、采购周期都有明显优势。

This article introduces the reaction from ethylene oxidation to ethylene oxide under silver catalyst,Shell ethylene glycol conversion MASTER process and OMEGA process,Shell catalyst characteristics,Walter Tosto reactor and working conditions;and introduces the alternative domestic EO YS-9010 catalyst,and the operation test of domestic catalyst in Shell ethylene glycol conversion process.The overall operation of the plant is excellent under the domestic EO catalyst instead of the Shell catalyst,and the purchase cost,technical service,and procurement cycle have obvious advantages.
