Abstract:
1. Burning process in which a carbon containing combustible is burned at least partly at a temperature higher than 700° C. and at a pressure higher than 10×10 5 Pa, said process being catalysed by at least a catalytic system comprising at least: a support containing at least one atom selected from the group consisting of aluminium and iron, at least one deposit contacting said support, said deposit containing at least Ce, Pr, Nd and La, whereby said deposit comprising a series of adjacent grains with a size greater than 1 μm, whereby said grains of said series have a first face in direct contact with the support and a second face not contacting the support, whereby said deposit covers a first portion of the support, while not covering a second portion of the support so as to define zones extending between adjacent grains, a first group of carbon nano particles contacting only a portion of the second face of one deposit, whereby leaving at least partly said second face of said deposit free of carbon deposit, a second group of carbon nano particles contacting only partly the second portion of the support, and a carbon containing structure extending between at least one carbon nano particle of the first group and at least one carbon nano particle of the second group.
