Class Information
Number: 518
Name: Chemistry: fischer-tropsch processes; or purification or recovery of products thereof >
Description: This class provides for processes which include (a) the reaction of hydrogen with carbon monoxide, carbon dioxide or mixtures of these carbon oxides (Fischer-Tropsch synthesis) to yield one or more carbon compounds, e.g., hydrocarbons, alcohols, esters, acids, ketones, aldehydes, etc., or (b) the purification, separation, conversion or treatment of one or more of the products resulting from the Fischer-Tropsch synthesis, such as by saponification, oxidation, adsorption, solvent extraction, etc.
