Study on activated clay prepared by fushun bentonite;

Study on improving the decoloring capacity of acid activated clay;

Preparation of 4A molecular sieves,activated clay and aluminum sulfate with the exhausted acid of bentonite;

By using a kind of simple,convenient,cheap and effective absorbent,or the activated bleaching earths,the article discussed the experiment of recycling the fried oil.

This paper studies several well-working absorbents to choose activated bleaching earths as the convenient,cheap and efficient fried-oil recycling substance,by comparing absorbing results.

The best bleaching condition: activated bleaching earths concentration is 5%; initial bleaching temperature is 80～120℃; bleaching time is 25 min.

6∶100,temperature 60℃,mixing time 20 min,m(activated bleaching earth)∶m(swill oil)5∶100,temperature 70℃,mixing time 20 min.

Activated carbon and activated bleaching earth bonjugating to use,at 85℃ and 15～20 min in decoloring process were propitious to increase decoloring ratio,fall acide value and POV,and improve smell,quality and stability on soja oil.

Base on physical and chemical characteristic of the hogwash oil,the absorption spectrum of the hogwash oil bleached by hydrogen peroxide and activated bleaching earth were studied.

Reaction process of direct preparation of p-cymene from turpentine over activated bentonite

This paper presents experimental results in the decolouring property of activated bentonite on the monomer dye in dyeing waste water.

An activated bentonite supported SO 2- 4Fe 2O 3 catalyst was used to synthesize trioctyl trimellitate.
