Catalyst for the production of synthesis gas and process for obtaining it

A catalyst for the production of synthesis gas, nickel-based, to be used in a steam reforming process, with greater resistance to the deposition of coke on its surface and catalytic activity, comprising:

• an inorganic oxide support;
• a mixture of Nickel, Lanthanum and Cerium oxides, in the form of their oxides (NiO, La2O3 and Ce2O3), which are impregnated simultaneously on the inorganic oxide support;
• the ratio between the mixture of NiO and La2O3 is comprised in a range of values between 6:1 (w/w) and 15:1 (w/w);
• the ratio of mixture of Ce2O3 and La2O3 comprised in a range of values between 2:1 (w/w) and 4:1 (w/w) and the total content of NiO in a range comprised between values between 5% (w/w) and 50% (w/w), preferably between 7% (w/w) and 30% (w/w);
• and
• a promoter element comprised in a range of values between 0.3% (w/w) and 2.0% (w/w).
