摘要
在接近工业操作条件下,综合考察催化剂制备放大、工业粒度催化剂、反应器放大及工业合成气等放大效应对合成气制低碳燃料醇催化反应的影响。在模试反应器中采用多段蛇管换热及移热与催化剂床层合理稀释,从而保证反应温度均匀。在模试中较系统地考察了温度、压力、空速及合成气中CO_2含量对合成低碳燃料醇反应的影响。在400—405℃,14—15MPa,尾气空速4000h^(-1)条件下进行了1000小时寿命试验,结果良好。低碳燃料醇的时空产率为0.21—0.25升醇/升催化剂/小时。在燃料醇中,甲醇占74—77%,异丁醇12—15%。本工作为合成气制低碳燃醇料工业试验装置的基础设计提供数据。
Catalysts prepared for commercial unit (pellet size φ6×6mm) were tested for the synthesis of fuel alcohols on a side line in Taiyuan Chemical Fertilizer Plant., Under conditions approaching those of industrial preparation, the effects of coal-based syngas and micro-pilot reactor on the synthesis of fuel alcohols have been investigated. By using diluted catalyst bed equiped with inter-stage heatexchange coils, the temperature distribution is sufficiently uniform. The effects of reaction parameters such as temperature, pressure, space velosity and the content of CO_2 in syngas have been investigated.In the 1000h long term test under reaction conditions of 400-405℃, 14-15MPa and 4000h^(-1) (with respect to exit gas), the alcohol product contained methanol 74-77% and isobutanol 12-15%, while the space time yield was 0.21-0.25 l alcohols/l cat/h.
