Process for the reaction catalu00ectica heterogeneous from a mixture of a gas and lu00ecquido reagent in a reagent carrying a metal monolith reactor catalu00ectico of catalu00ectico under reaction conditions of FasAnd for a time sufficient to generate lu00ecquida carbonaceous and deactivating sub products and process for the catalu00ectica heterogeneous reaction on a mixture of hydrogen and dinitrotoluene in a reactor.Lu00ectico of monolith with nu00ecquel and palladium as metals catalu00ecticos under reaction conditions of phase for a time sufficient to generate lu00ecquida carbonaceous and deactivating sub products ".The invention is a process for regenerating catalytic monolith reactors employed in the liquid phase hydrogenation reactions.Particularly those types of reactions involving nitroaromu00e1ticos compounds.The metal in the catalytic monolith catalytic reactor are deactivated by carbonaceous and sub products of deactivation and must be regenerated to extend the service life of the catalyst and reduce CCosts.The regeneration process involves two stage: initially through a gas mixture of oxidizau00e7u00e3o through catalytic monolith reactor at an elevated temperature and for a time sufficient pTo remove carbonaceous and deactivating sub products, and then passing a gas through the catalytic reduction reactor monolith previously exposed to gas under conditions to reduce the metal oxidizau00e7u00e3oA catalytic state reduced.
