石蜡白土精制中掺加废催化剂的工艺研究

摘要

针对催化裂化装置废催化剂的处理现状，进行了在石蜡白土精制中掺加废催化剂的工艺研究实验。结果表明，在白土中掺入40％的废催化剂生产出来的石蜡产品，与用传统的白土精制工艺生产出来的产品在光稳定性、色度等多项指标上基本一致，并且有着降低消耗、节约成本、减少环境污染的多重功效。精制石蜡后的废渣可用于生产建筑4密封剂。%A new process of paraffin refining by using clay blended with 40% of spent catalyst was studied . The results showed that the paraffin product by using clay blended with 40% of spent catalyst had the similar properties, such as photostability, colority, as compared with those of traditional clay refining process. The method had the advantages of lower consumption, lower cost and environmental protection.The deoiled sludge could be used in the building sealant.
