Class Information
Number: 585/260
Name: Chemistry of hydrocarbon compounds > Adding hydrogen to unsaturated bond of hydrocarbon, i.e., hydrogenation > Hydrocarbon is contaminant in desired hydrocarbon > Hydrogenation of diolefin or triple bond > Using catalyst or support of defined structure, surface area, or pore size
Description: Subject matter where the hydrogenation of a bond in a contaminant takes place in the presence of a catalyst or support of specific structure, e.g., gamma-alumina, or of a specific surface area or pore size, e.g., 3 meters per cubic meter, 5-7 angstroms, etc.
