DEFINITION

Classification: 585/535

With heat conservation or using solid inert heat carrier, e.g., regenerative furnace, etc.:

(under subclass 534) Subject matter wherein heat generated in the process, e.g., by reaction, catalyst regeneration, adsorded by quenching reactants, etc., is put to use in the process or wherein an inert solid material is employed to supply heat to the synthesis reaction or to absorb heat from the synthesis reaction.
