Hydro-treated Gasoline: Cracked Light Gas Oil and Isoheptanes Desulphurised with Hydrogen over Cobalt Molybdate at 700 °F (Gulf, US 3,071,535)
Sulphur in petrol and fuel oil is removed by heating the oil with hydrogen over a cobalt molybdate catalyst. Gulf treats its cracked light gas oil together with isoheptanes this way; a small gasoline fraction comes out alongside the desulphurised gas oil.
Result (Gulf's example, barrels per day): from 10,555 of FCC light gas oil and 1,796 of isoheptanes, 1,825 of hydro-treated gasoline and 10,559 of treated light gas oil for No. 2 fuel oil.

Charge the light gas oil and isoheptanes
Charge the light gas oil and isoheptanes
Feed the light gas oil from the catalytic cracker (10,555 barrels a day) and the isoheptanes and heavier from the isomerisation prefractionator (1,796).

Desulphurise at 700 °F and 600 psig
Pass the oil with hydrogen over cobalt molybdate on alumina at, for example, 700 °F and 600 pounds per square inch gauge, at 4 volumes of oil per volume of catalyst per hour and 4,000 standard cubic feet of hydrogen per barrel.

Separate the gasoline and the gas oil
Separate the gasoline and the gas oil
Separate the products: fuel gas, hydro-treated gasoline (1,825) for petrol blending and treated light gas oil (10,559) for No. 2 fuel oil. Gulf does not describe the separation. Ours: a fractionating still.
