(under subclass 165) Processes wherein (1) the heated solids, are employed to heat the fluid prior to entry to the gravitating bed or (2) cool solids are employed to extract and/or recover heat from the effluent from the gravitating bed zone.
(1) Note. This subclass contains, for example, processes of maintaining a better thermal balance in the system by use of the solids to preheat the feed or cool the products. Undesirable side reactions may be prevented by quickly cooling the products below reaction temperatures.
