Class Information
Number: 585/826
Name: Chemistry of hydrocarbon compounds > Purification, separation, or recovery > By contact with solid sorbent > With specified sorbent rehabilitation procedure or agent, e.g., desorbent, etc.
Description: Subject matter in which a procedure for rehabilitation of the sorbent is described as more than mere "desorption", "recovery of sorbed material", or "purging", etc., or in which an agent for removing desorbed material is described in more specific terms than merely a "desorbent", etc.
