摘　　要：简述了T-Star沸腾床加氢工艺的特点及优势。分析了T-Star催化剂的失活原因,合理的催化剂置换速率可将催化剂上的积炭、Fe和Ca的沉积量维持相对稳定;而磨损导致催化剂藏量降低对整体活性的影响较小。探讨了催化剂整体更换和日常置换两种不同使用方案的优劣。最后提出了开发新型催化剂和优化使用方案是今后工作的重点。In this paper, the characteristics and advantages of T-Star ebullated bed hydrogenation process is brief descripted. The deactivation reason of T-Star catalyst is analyzed, The reasonable catalyst replacement rate can maintain relatively stable deposition of carbon, iron and calcium on the catalys; But in the reactor catalyst decrease for abrasion has little effect on overall activity. The pros and cons is discussed of two different using scheme as a whole replacement and daily replacement. In the last,put forward the developing new catalysts and optimization of using scheme is the key work in the future.
