Abstract:
A process for evaluating the performance of a plurality of solid particle catalysts comprising:a) containing the plurality of solid particle catalysts in an array of parallel reactors with each reactor containing a bed of catalyst; b) contacting, simultaneously, at reaction conditions and solid-gas two-phase operating conditions, each bed of catalyst with at least one gaseous reactant to form an effluent of each reactor; c) ramping, simultaneously the superficial velocity of the gaseous reactant to each bed of catalyst while monitoring the effluents to define, for each bed of catalyst, a range of superficial velocities which result in fluidization of the bed of catalyst; d) fluidizing, simultaneously, at reaction conditions and solid-gas two-phase operating conditions, each bed of catalyst through contact with the gaseous reactant at a superficial velocity within the corresponding range of superficial velocities; and e) analyzing each of the effluents to determine its chemical composition.
