Abstract:
Since many years carbon dioxide reduction by hydrogen through catalyst processes is a usual way from the Paul Sabatier reaction to produce CH4. this process is able to be done from thermal process by using an heterogeneous catalyst such as zirconia cerium support with nickel sites for the hydrogen reduction of CO2 .However this reaction is well working ( 85%-90%) at 350?c and its selectivity depends of the secondary reactions such us carbon monoxide or carbon deposit which appears above 350?C.
