裂化催化剂再生过程中固体表面对CO氧化速率的影响

THE EFFECT OF SOLID MATERIALS ON THE OXIDATION RATE OF CARBON MONOXIDE DURING CRACKING CATALYST REGENERATION

利用流动法微型反应器研究了不同固态物质(石英砂及Si—Al、Y—9、CRC—1催化裂化催化剂)在600～680℃反应温度范围内对CO氧化速率的影响。考察了CRC—1催化裂化剂的老化程度及污染金属(Fe、Cu、Ni、Na)对CO氧化反应速率的影响,为再生器模型的建立和生产应用提供了基础数据。

The effect of different solid materials (quartz, silica-alumina, Y-9 and CRC-1 cracking catalysts) on the oxidation rate of carbon monoxide at the temperature from 600℃ to 680℃ was investigated in a steady flow reactor. The effects of hydrothermal treatment and contaminant metals (Ni, Na, Fe, Cu) of CRC-1 catalyst on the oxidation rate of carbon monoxide were also examined. The results provide the necessary data for regenerator modelling.
