The carbonization of a petroleum residue was studied by using a tube bomb, with which the pressurized carbonization of rapid heating was operable under conditions similar to those employed in a commercial delayed-coking process. Such a carbonization provided a small lump of needle coke (ca. 8 g), which was evaluated to be comparable to a commercial one prepared from the same feedstock in terms of appearance, optical texture, coefficient thermal expansion value, and bulk density. The pressure and heating rate were found to be influential factors in the production of such a needlelike lump coke in the tube bomb. Carbonization properties of fractions of a petroleum residue were also examined by the same apparatus to evaluate them as the feedstock for the needle coke.
