    摘要: Properties of premium coke are improved by coking the feed at a temperature lower than the normal coking temperature and thereafter subjecting the coke to a heat soak at substantially the same temperature as the temperature at which the coke was formed.

    摘要: A process for providing more uniform premium coke in a delayed coking operation by adding an aliphatic petroleum fraction to the premium coking feed during the latter part of the coking cycle. Preferably the aliphatic petroleum fraction is added gradually and is increased in quantity over the period of addition.
