Delayed coking is commonly used to produce a mixture of gases, distillate liquids and carbonaceous solids by the thermal treatment of high-boiling petroleum feedstocks. The formation of carbonaceous solids is of interest in this study. Apart from the production of premium graphitizable cokes needle cokes from selected aromatic feeds, the cokes usually produced are porous solids ('sponge' cokes). A less desirable form of solid carbon, occasionally co-produced with sponge coke, is known as 'shot' coke and consists of small hard spherules of low porosity, typically about 5 mm diameter which can aggregate into large clusters and can occur dispersed with sponge coke to varying extents. The studies described in this paper were conducted in order to obtain clearer indications of the factors which contribute to shot coke formation.
