摘要：

Carbonization studies of petroleum vacuum distillation residua have been carried out on a laboratory scale with the objective of developing a better understanding of the causes and mechanisms of shot coke formation in delayed coking. The rates of carbonization inversely relate to the extent of mesophase development in the semicoke. The asphaltenic fractions carbonized rapidly. The addition of aromatic petroleum materials enhanced mesophase development commensurate with reducing the rate of carbonization. While the microstructural features of shot coke are reproducibly produced in the laboratory, the characteristic spherical morphology is not and appears to be determined by conditions obtaining in large-scale operation.
