Catalyst for steam cracking reactions and related preparation process

   
   

Catalyst for steam cracking reactions consisting of pure mayenite having the general formula: 12CaO.7Al.sub.2 O.sub.3 having an X-ray diffraction spectrum as indicated in Table I, obtained with a preparation process comprising the following steps: dissolution of salts containing calcium and aluminum with water; complexing of the dissolved salts by means of polyfunctional organic hydroxyacids; drying of the solution resulting from the completing in order to obtain a solid precursor product; calcination of the solid precursor product at a temperature ranging from 1300 to 1400.degree. C. for at least two hours.
