催化剂的活性、选择性和寿命是否达到生产要求,是否具备催化剂优良性能的要求,除了与催化剂本身的性能和制备方法有关外,还与使用过程是否合理、操作过程是否稳定有关。若催化剂使用不当就不能充分发挥催化剂的优良性能,就达不到设备的生产能力,甚至影响催化剂的使用寿命,使催化剂过早地失去活性,甚至被迫停车,造成经济损失。所以优良的催化剂必须有合理的使用过程才能发挥它的优良性能。催化剂在使用过程中要经过以下几个阶段。
Catalyst activity, selectivity and life expectancy meet the production requirements, whether the catalyst with excellent performance requirements, in addition to the performance of the catalyst itself and preparation methods, but also with the use of the process is reasonable, the operation is stable. If the improper use of the catalyst can not give full play to the excellent performance of the catalyst, the equipment can not reach the production capacity, or even affect the life of the catalyst, the catalyst premature loss of activity, or even forced to stop, resulting in economic losses. Therefore, good catalyst must have a reasonable use of the process in order to play its excellent performance. The catalyst in the process of using to go through the following stages.
