本文较系统地介绍了利用煤系中高岭岩生产聚合氯化铝、白炭黑的全过程,对生产成本,利润也作了简要分析,并提出了解决环保问题的办法。该工艺的特点是生产成本低、产品质量好、生产无废渣且经济效益显著,还为综合利用煤系中高岭岩(或煤矸石)开辟了一条新的途径。 This paper introduces systematically the whole process of producing polyaluminum chloride and white carbon black with coal kaolinite, analyzes the production cost and profit briefly, and puts forward some solutions to environmental problems. The process is characterized by low production costs, good product quality, no waste production and significant economic benefits, but also for the comprehensive utilization of coal-based kaolinite (or coal gangue) has opened up a new avenue.
