(under subclass 20) Process wherein components of the catalyst or sorbent are separated on the basis of specific gravity, density, size, shape, or other property of differing discrete small bodies of the composition.
(1) Note. This subclass includes abrasion with segregation of the catalyst or sorbent from abraded particles. It also includes segregation of catalyst and foreign particles such as dust.
(2) Note. Flotation separation is an example of a process classifiable here.
