【摘要】：以油頁巖灰渣為原料,采用酸法制備聚合氯化鋁,考察了酸溶條件對(duì)產(chǎn)品的鋁浸出率與鹽基度的影響。制備聚合氯化鋁的最佳酸溶條件為:酸的質(zhì)量分?jǐn)?shù)22%,酸量比n(Al2O3)/n(HCl)為1∶13,酸溶溫度125℃,酸溶時(shí)間3 h。此條件下,鋁浸出率為73.65%,制備的液體聚合氯化鋁的鹽基度為77.51%。所制聚合氯化鋁符合國家標(biāo)準(zhǔn)(GB 15892—2003)中Ⅰ類液體一等品標(biāo)準(zhǔn)。
[Abstract]:Polyaluminium chloride was prepared from oil shale ash by acid method. The effects of acid solution conditions on the leaching rate and basicity of aluminum were investigated.The optimum conditions for the preparation of polyaluminium chloride are as follows: the mass fraction of acid is 22%, the ratio of acid content to Al _ 2O _ 3 / nHCl is 1: 13, the acid solution temperature is 125 鈩，
