含锌废脱硫催化剂的合理利用

用含锌废脱硫催化剂生产附加值较高的活性氧化锌比生产硫酸锌在经济上更为合理，用氨浸法和氯化铵法生产活性氧化锌的浸取液可回收循环使用，单耗低、工艺简单、无三废，是硫酸法的替代工艺。

Utilization of Used Desulfurate Catalyst Containing Zinc

It is economically beneficial to produce active zinc oxide with used desulfurate catalyst containing zinc than to produce zinc sulfate. The leaching solution from the production of active zinc oxide with ammonia leaching process and ammonia chloride process can be recovered and recycled for use. This process features low in individual consumption , simple in process and with no three wastes and is an alternative to the sulfuric acid process .
