Methods of increasing the yield of petroleum electrode coke

Abstract

1. The effect of pressures from 1 to 30 atm on the yield and quality of coke in the coking of various types of petroleum residues has been studied. 2. It has been established that the yield of coke can be increased by 5–11%, calculated on the feedstock, by increasing the pressure in the reaction zone to 6 atm. 3. Based on the experimental data, empirical relationships have been found for calculating the yield of coke when coking under pressure. 4. The effect of preliminary thermal condensation of coking feedstock on the yield of coke has been studied. It is shown that the use of the method described provides the possibility of increasing the yield of coke by 4–15%.
