通过操作看出较低的再生温度有利于保护催化剂。
According to the operation data, the lower regeneration temperature is good for protecting catalyst.
再生温度和环境空气含湿量对系统制冷量和性能系数的影响较大，而环境空气温度的影响较小；
The regenerating temperature and the humidity ratios of ambient air are two main factors affecting system performance, while the temperature of ambient air functions less.
对催化剂的分析表明，催化剂破碎主要由于原料中钠、钒含量超标、再生温度过高和提升管预提蒸汽线速过高所致。
The causes behind breakage of the catalyst are excessive sodium and vanadium content in the feed oil, excessively high regeneration temperature and excessively high steam velocity in riser pipe.
