HIGH THROUGHPUT DEVELOPMENT METHOD FOR CATALYTIC HYDROPROCESSING OF DIRTY FEEDSTOCKS

摘要

A method for determining a set of operating parameters for a commercial scale plug flow catalytic process and reactor system for hydroprocessing dirty feedstocks, comprises the steps of: feeding selected partial pressures of said feedstock and hydrogen to the inlet the first reactor stage of a first composite multi-stage series-connected laboratory scale plug flow reactor including at least three reactor stages, the catalyst beds of each of said reactor stages including catalyst particles capable of catalyzing the removal by hydrogen of heteroatoms from said heterocyclic molecules; sampling the effluents of each of said reactor stages; measuring the concentration of heterocyclic molecules in said dirty feedstock in the concentrations of heterocyclic molecules and intermediate and final products and by products of the catalytic reaction in the effluents of each of said reactor stages.
