摘要: The deactivation of cracking catalysts by coking with vacuum gas oils (VGO) is studied in relation to the chemical due site coverage, and increase diffusional limitations. These two phenomena are taken into account a simple function versus catalyst coke content. parameters this discussed feedstock analysis change effective diffusivity
