The paper introduces the methods of making basic Aluminium Chloride from coal ash, and also studies the main factors of making process. 用粉煤灰制取碱式氯化铝的方法,研究了制取过程中的主要影响因素。
In this experiment, two kinds of modified filter material were prepared, in which quartz sand was chosen as a carrier to be coated with aluminium chloride and magnesium chloride by the deposition process at alkaline condition, respectively. 本试验以石英砂为载体,以氯化铝和氯化镁为改性剂,采用碱性沉积法制备了铝盐改性石英砂和镁盐改性石英砂。
