渣油固定床加氢处理技术

Resid Fixed Bed Hydrotreating Technology

结合渣油固定床加氢处理技术的发展,探讨了催化剂、原料油处理、单段与两段反应、单系列与双系列反应器、反应器结构及循环氢气与液体反应生成物的分离、反应及氢耗等问题。

The resid fixed bed hydrotreating technology,including operating condition of HDS,action of bis-catalyst sys-tem,effect of catalyst loading way and character of three typical process flow diagrams(single-stage,doub-le-stage and double pass)were described all-sidedly.The main chemical reaction and H2 consumption in resid hydrotreating process was also discussed.Furthermore, a comparision between indirect-HDS and direct-HDS in the point of view of engineering technology was made.
