The ethylbenzene dehydrogenation unit of a petrochemical company uses low water ratio catalyst for production of styrene monomer. Due to long time operation under low water ratio,catalyst coked too fast,which shortened catalyst operation cycle. High temperature steam coking technology and potassium supplementation technology were applied ,and this successfully solved the industrial difficulty of low water ratio catalyst coking.
