of sintered and graphitized carbon was obtained by discharge for a duration time from 60 set to 300 set under a pressure of 175-350 kg/ems. The degree of sintering and graphitization of the compact specimen was examined by microscope and X-ray analysis. The more compactly sintered carbon for petroleum coke and thermal black was obtained by using a longer discharging time. Some of the sintered thermal black specimens were gradually decomposed to fine powders within a month or so.

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
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 temperatu
