Abstract
Procedimiento para la regeneracion de un catalizador heterogéneo usado para la obtencion de compuestos conteniendo grupos NH2 por hidrogenacion de compuestos que contienen por lo menos un enlace de carbono-nitrogeno no saturado, con hidrogeno, procedimiento que comprende las etapas: a) se interrumpe la alimentacion del compuesto a hidrogenar, y b) se trata el catalizador heterogéneo con un compuesto de la formula (1): R1R2N-CO-R3, en donde R1: significa hidrogeno, alquilo C1-4; R2, R3 significan, independientemente, hidrogeno, alquilo C1-4, o representan juntos un grupo alquileno C3-6, o sus mezclas a una presion en la region de 0,1 a 30 MPa y una temperatura en la region de 100 a 300 degree C, siendo preciso, que el compuesto de la formula 1 esté presente en forma líquida en el tratamiento. En dicho procedimiento se puede regenerar un catalizador heterogéneo usado para la hidrogenacion de adipodinitrilo, o adipodinitrilo en hexametilendiamina, o bien adipodinitrilo en una mezcla que contiene hexametilendiamina y 6-aminocapronitrilo. El catalizador heterogéneo puede contener como componente catalíticamente activo un compuesto de un elemento seleccionado del grupo que abarca hierro, cobalto y níquel o sus mezclas. La regeneracion puede realizarse en presencia de hidrogeno, o bien en la etapa a) se interrumpe la alimentacion del hidrogeno.
