Claims13
A catalyst system comprising a Ni ion-exchanged zeolite of Linde Type A having a Ni content of 1 to 10 wt % based on the total mass of the catalyst, characterized in that the cations of potassium, sodium or calcium incorporated in the zeolite are at least partially exchanged with other alkali metal or alkaline earth metal ions, wherein the proportion of alkali metal and/or alkaline earth metal ions introduced is between 0.02 and 8.8 wt %.
