In the present invention there is disclosed a selective hydrogenation process of dinitrile compounds in the presence of a catalyst containing a metal selected for the group 8 of the Periodic System of Elements, whereby this catalyst comprises zeolite with pore size within the range of 0.3 to 0.7 nm. This zeolite structure is preferably selected from a group of structures comprising ABW, AEI, AFT, ANA, ATN, ATV, ATT, AWW, BIK, CAS, CHA, DDR, AEB, EDI, ERI, GIS, JBW, KFI, LEV, LTA, MER, NAT, PHI, RHO, THO, YUG. |
