DEFINITION
Classification: 585/503
With heat conservation or using apparatus of recited composition:
(under subclass 502) Subject matter wherein heat generated in the process, e.g., by reaction, catalyst regeneration,
adsorbed by quenching reactants, etc., is put to use in the process or in which the chemical composition of apparatus used in the process is specified.
(1) Note. Patents placed herein are not cross-referenced to subclasses 910+ and 920 unless the processes therein are disclosed as applicable to other than polymerization processes.
