<p>The present invention relates to a method for the preparation of a plurality of supported catalysts, the said supported catalysts comprising an active phase on a support, in a first vessel and at least one second vessel, said vessels -being arranged in parallel, -having a first compartment comprising an inlet, -a vessel outlet, the first compartment being separated from the vessel outlet by a porous element, impermeable for the support, the method comprising the steps of: A)feeding support into the first compartment of the first and second vessels, B) feeding impregnation liquid comprising the active phase into the first compartment of the first and second vessels, under pressure conditions in the said vessels preventing passage of the impregnation liquid through the porous element, C) impregnating the support with impregnation liquid comprising contacting the support with the impregnation liquid in the first compartment of the first and second vessels, under pressure conditions in the said vessels preventing passage of the impregnation liquid through the porous element, D) removing impregnation liquid from the upstream compartment of the first and second vessels through the pores of the porous element of the said vessels in the direction of the outlet of the said vessels under pressure conditions in the said vessels allowing passage of the impregnation liquid through the porous element, leaving the supported catalyst in the first compartment of the respective first and second vessels. Further the present invention relates to an apparatus and a vessel suitable for performing the method.</p> |
