Abstract
一种处理氯铝酸类离子液体废催化剂和碱性废水的方法和系统。该方法包括：1)将氯铝酸类离子液体废催化剂与浓盐水混合进行水解反应，至废催化剂的残留活性完全消除，得到酸性水解液和酸溶油；2)将酸性水解液与包含碱性废水的碱液混合进行中和反应，至反应体系为弱碱性，得到含有金属氢氧化物絮体的中和液；3)将中和液与絮凝剂充分混合并实施沉降分离，收取上层的浓盐水回用于水解反应，同时收取下层的浓缩絮体；4)对浓缩絮体进行脱水处理，收取湿固渣，并将脱出的浓盐水回用于水解反应；5)对湿固渣进行干燥处理，得到干化固渣。上述方法能够温和地消除废催化剂的活性，工艺操作的稳定性和安全性好，回收油品的品质高。
