摘要
分析了Pd/C催化剂活性降低的原因,介绍了天津PTA装置在Pd/C催化剂活性降低时采取的工艺控制手段。经过工艺调整,延长了催化剂的使用寿命。Pd/C催化剂的最长使用寿命达到6.13万倍,超过设计寿命1倍多。
The reasons that cause the decrease of Pd/C catalystic activity are analyzed. In PTA plant TPCC, many methods for process control are taken when the Pd/C catalytic activity is decreased, which prolongs the life-time of catalyst. The longest lifetime of catalyst can achieve 61.3 thousand times, which is more than 1 times than the designed lifetime.
