✦ Synopsis

Catalytic converters installed in 1975model automobiles oxidize sulphur dioxide present in the exhaust gas to a sulphuric acid mist. This may constitute a serious health hazard. Sulphur can be removed from gasoline, down to any desired level, by the use of sodium metal at 250-325Β°C.

Hydrogen is not needed. Sodium can be used to desulphurize petroleum fractions before they are converted to gasoline. Jet-aircraft fuels can also be desulphurized by sodium treatment.

Desulphurization of a fluid coke produced commercially from a conventional petroleum crude oil was attempted. Direct hydrodesulphurization of the coke at 700Β°C resulted in ~31 w% sulphur removal; however, impregnation of the fluid coke with trace amounts of sodium hydroxide and subsequent hydrodesul
