具有不同活性中心的固体催化剂的失活模式

摘要

An approach is suggested to distinguish different types of active sites responsible for different reactions on bifunctional catalysts.The model assumes a non-uniform vulnerability of active sites that depends on their location.Problems on the relationship between the dis-persion of the active phase and selectivity are discussed.The effect of coke formation on the activity change of different sites is analyzed.
