Class Information
Number: 585/901
Name: Chemistry of hydrocarbon compounds > Catalyst and recycle considerations > With recycle, rehabilitation, or preservation of solvent, diluent, or mass action agent
Description: Collection of documents (under unnumbered subclass CATALYST AND RECYCLE CONSIDERATIONS) (a) to prevent loss of, (b) to restore effectiveness, or (c) to return to a stage of a process, either directly to indirectly, from which it has been withdrawn from use in that stage, a material which is a solvent or diluent or an agent, usually a normally undesired by-product of the process, which regulates the equilibrium of the process to favor production of desired product.
