Abstract

Abstract A REACTOR FOR CONTACTING HOT, LIQUID-PHASE OR MIXEDPHASE HYDROCARBONS WITH A COMPACT MASS OF GRANULAR CATALYST MAINTAINED WITHIN THE REACTOR AS A FIXED BED; IN WHICH REACTOR, THE LIQUID HYDROCARBONS, WITH OR WITHOUT ACCOMPANYING GASEOUS REACTANTS, ARE CAUSED TO FLOW UPWARDLY THROUGH THE BED, IN A FLOODED OPERATION, AT SUCH RELATIVELY-HIGH RATE OF FLOW AS TO CAUSE POSSIBLE MASS LIFT ING AND FALLING OF THE BED OR SUCH VOLUMETRIC EXPANSION THEREOF AS TO CREATE AN INTERNAL DISTURBANCE OF THE CATALYST PARTICLES RESULTING IN DETRIMENTAL ATTRITION OF THE CATALYST. THE REACTOR IS PROVIDED AT ITS UPPER END AND SPACED THEREFROM WITH A PERFORATED FRUSTO-CONICAL MEANS TO CONTAIN THE UPPER PORTION OF THE BED. MEANS ARE PROVIDED FOR AUTOMATICALLY ADDING INERT MATERIAL TO THE TOP OF THE BED THROUGH THE FRUSTO-CONICAL MEANS FROM A RESERVOIR MOUNTED ON TOP OF THE REACTOR VESSEL.
