US5008226A - Process for making acid activated bleaching ...

A process for making acid-activated bleaching earth from certain naturally occurring mixtures of calcium bentonite and attapulgite clay. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower ...

Bleaching Earths

Why Bleaching Earth selection is important in a CPO refining plant 1. A typical dry degumming process only hydrates out 90% of the total gums present in the CPO. 2. A well engineered wet acid activated clay is able to adsorb all of the hydrated gums together with other trace metal contaminants and most of the
