摘要:

对催化裂化(FCC)催化剂胶渣中有用元素进行回收,不仅实现了资源的回收利用,而且也消除了对环境的污染。以天然膨润土为原料制备得到提纯土,再制备得到活性白土,以提纯土和活性白土为吸附剂吸附催化剂胶渣中的铼离子,考察了吸附条件与性能。结果表明:活性白土对胶渣中铼离子的吸附能力强于提纯土,当活性白土的用量为0.9 g、胶渣溶液中铼离子初始质量浓度为11 mg/L、溶液的pH为4.0、吸附温度为25 ℃时,活性白土对铼离子的吸附率达到93%。该研究为FCC催化剂生产过程中有用元素的回收利用提供了技术支持。

Abstract:

Recovery of the useful elements in FCC catalyst slag is not only realizes the recycling and utilization of resource,but also eliminates environmental pollution.Purified clay was prepared with natural bentonite as raw material,and then the activated clay was prepared.Rhenium ions in catalyst slag were adsorbed with purified clay and activated clay as adsorbents,and adsorption conditions and properties were investigated.The result indicated that the adsorption capacity of rhenium ion in the slag solution of activated clay was higher than that of purified clay,as adsorption dose of active clay was 0.9 g,initial mass concentration was 11 mg/L,solution pH=4.0,the adsorbing temperature was 25 ℃,then the adsorption rate of rhenium ion on active clay reached 93%.This study provided technical support for the recovery and utilization of useful elements in FCC catalyst production.

Key words: rare earth ions, FCC catalyst slag, activated clay, rhenium ions
