摘要: 活化是膨润土深加工中的一个基本工艺过程.活性白土既可直接用作医药、化妆品和涂料等的原料,也可用于油品制造的脱色以及碱性、极性基团的吸附工艺,还可用作中间产物,继而加工成为NaA型沸石等其它产品.本文用广东南海某地的膨润土矿为原料.研究了制备具有较高白度的活性白土的工艺过程.

Abstract: The activated bentonite was prepared with the bentonite from Nanhai,Guang-dong Province.The technological process and reaction conditions were studied.The compo-sition of the product was determined by chemical analysis,IR spectra and X-ray diffractionmethods.The decolorizing efficiency,the activation grade and the free acid content of theproduct were measured also.

Key words: bentonite, activated bentonite, activation technology
