摘要

研究了水泥窑协同处置废FCC催化剂对窑运行工况及水泥熟料质量的影响，开展了废FCC催化剂特性分析、重金属浸出率及配伍方案分析试验，介绍了生产实践中协同处置废FCC催化剂的不足以及废FCC催化剂对窑尾烟气排放、生产区域水质、熟料质量等方面的影响。研究结果表明，利用水泥窑协同处置废FCC催化剂时，需提前做好配伍计算、强化过程质量控制；废FCC催化剂应与水泥原料配比充分融合。对于氧化铝含量约35%、氧化硅含量约33%的废FCC催化剂，处置量宜<1.6t/h。

Abstract:

In this study, the effects of coordinated disposal of waste FCC catalyst in cement kilns on kiln operation conditions and clinker quality were studied, which carried out the characteristics analysis of waste FCC catalyst, heavy metal leaching rate and compatibility scheme analysis test. The deficiencies of collaborative disposal of waste FCC catalyst in production practice were introduced, meanwhile including the effects of waste FCC catalyst on kiln tail gas emission, water quality and clinker quality. The results show that compatibility calculation and quality control should be strengthened in advance when using cement kiln to dispose waste FCC catalyst. The waste FCC catalyst should be fully integrated with the cement raw material ratio during the disposal process. For waste FCC catalysts with alumina content of about 35% and silicon oxide content of about 33%, the disposal amount should be controlled within 1.6t/h.

Key words: waste FCC catalyst coordinated disposal compatibility scheme heavy metal leaching rate quality control
