Class Information
Number: 585/634
Name: Chemistry of hydrocarbon compounds > Unsaturated compound synthesis > With heat conservation or using solid or molten inert heat carrier, e.g., regenerative furnace, etc.
Description: Subject matter wherein a synthesis process includes the withdrawal of heat from an exothermic part of the process, e.g., catalyst regeneration, quenching of reaction products, etc., and transfer of this heat to an endothermic part of the process, e.g., feed-stream preheating, dehydrogenation, etc., or in which heat is conveyed to an endothermic part of the process by preheating a solid or melted solid.
