He temperature programmed oxidation study showed that coke was formed over the catalyst on two different sites:(1) deposited on the CPMVs which can be burn off at a low temperature;(2) deposited on the MgO which could only be removed at higher temperature.

PO研究结果表明，积碳在催化剂上有两种存在位置：一种沉积在钼钒磷酸铜表面，这种位置的积碳在低温下容易被烧除；另一种沉积在载体氧化镁的表面，需要高温才能烧除。

In order to prolong the life-span of fire-proof material, Besides guaranteeing the quality, during construction,we should pay attention to the water amount, curing condition and air vent setting, during kilning period, baking-heating up curve should be set down according to refractory performanc...

要延长耐火材料的使用寿命，除了保证耐火材料本身质量外，施工时应注意加水量、养护和排气孔的设置；烘窑时应根据耐火砖的性能合理制定烘烤升温曲线并控制升温速度(通常为30~50℃/h)，在冷窑升温时要尽快通过60~295℃温度区，以防氧化镁的水化；在正常生产中，要维持工况稳定，保护好窑皮，避免系统频繁开停等。

Furthermore, the performance of refractory with the light magnesia powder is better than that with the alumina powder.
