The preparation of a Ni catalyst for methane reforming with CO2 was studied. A zeolitized tuff from an Argentine deposit was used as starting material. Clinoptilolite was treated with HCl to obtain a decationized zeolite (HCLI) with modified surface properties; the process eliminates species that diminishes the gaseous diffusivity in zeolite channels and increases the number of cationic sites in the network. The acid form of the zeolite was used as support of active phase. The new material was characterized by means of different physicochemical techniques as in situ XRD, FTIR spectroscopy, thermal (TPR) and surface (BET) studies. The dry reforming of methane was used as test reaction. A relationship between the metal support interaction and catalytic activity was detected.
