DEFINITION

Classification: 422/211

Including solid, extended surface, fluid contact reaction means; e.g., inert Raschig rings, particulate absorbent, particulate or monolithic catalyst, etc.:

(under subclass 129) Apparatus including solid extended surface fluid contact reaction means, i.e., means providing a relatively large solid contact surface area within the reaction zone wherein large surface area presents multiple reaction sites for contact by the reaction mixture and, thereby, enhance the rate and/or the completeness of the reaction, including; e.g., inert Raschig rings, particulate absorbent, etc.
