Methodology for the Study of Vacuum Gas Oil Hydrocracking Catalysts in a Batch Reactor – Coupling of GC-2D Data with Vapour-Liquid Equilibrium
A new approach for studying complex feedstock conversion with a hydrocracking catalyst is proposed in this work. The reaction was carried out in a batch reactor. Vapor and liquid samples were taken at different reaction times, both at operating conditions and after cooling to room temperature. Two-dimensional gas chromatography was used to characterize in detail the composition of condensed vapor and of liquid phases, while gas samples were analyzed by conventional gas chromatography. From room temperature conditions data, vapor fraction of the hydrocarbon mixture and compositions of each phase at reaction condition were calculated and validated. Following this methodology then allows a simple tracking technique for the study of complex hydrocarbon mixture reactions in liquid and vapor phases.
