• C10G 45/02 to eliminate hetero atoms without changing the skeleton of the hydrocarbon involved and without cracking into lower boiling hydrocarbons; Hydrofinishing
• C10G 45/32 Selective hydrogenation of the diolefin or acetylene compounds
• C10G 45/44 Hydrogenation of the aromatic hydrocarbons
• C10G 45/58 to change the structural skeleton of some of the hydrocarbon content without cracking the other hydrocarbons present, e.g. lowering pour point; Selective hydrocracking of normal paraffins (C10G32/00 takes precedence; improving or increasing the octane number or aromatic content of naphtha C10G35/00)
• C10G 45/72 Controlling or regulating
