摘要：The effect of basic operating variables and technologies on reaction behaviors during the whole coking half cycle of an empty coke drum in three industrial delayed coking units was examined. It was observed that the temperature of the liquid streams and yields for gasoline and diesel oil in the coke drum were all stable after a few hours. Since then it was demonstrated that the coke drum was operated like a steady-state flow-type stirred-tank reactor (STR). These results will pave the way for the theoretical calculation of the coke drum for simulation and prediction.
