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.
