✦ Synopsis

A study has been made of the desulphurization of Syrian petroleum coke, containing 8.83% sulphur, by calcination in a Tamman furnace at high temperatures (l OOO-16OO'C) using heating times up to 4 h. Sulphur elimination (up to 96% in 30 min at 16OO'C) was found to increase with calcination temperature and heating time and to decrease with increase in ash. Reactivity of petroleum coke increases with the extent of sulphur elimination, but this is counteracted to some extent by the annealing effect of the higher temperature.

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
