                         (CLR) processes are technologies in development, considered as 
                         economically viable alternatives for CO2 mitigation. Both 
                         processes employ two interconnected reactors (air reactor and fuel 
                         reactor), by which oxides particles (called oxygen carriers) 
                         circulate. CLC process produces heat with inherent separation of 
                         CO2 from gaseous hydrocarbons combustion. CLR process performs the 
                         fuel partial oxidation, generating synthesis gas (H2 and CO), 
                         which is the major industrial intermediate for hydrogen (H2) and 
                         other hydrocarbons production, thru Fischer-Tropsch reactions. The 
                         employment of OCs enables the total or partial oxidation of fuel, 
                         in the absence of atmospheric air, which allows great reduction of 
                         the separation costs. Nickel-based OCs are the most investigated, 
                         showing high performance and reactivity. This work presents the 
                         synthesis of OCs composed by different contents of nickel oxides 
                         supported on alumina, textural, physical and chemical 
                         characterizations by several techniques, and experimental results 
                         obtained when these materials were applied to CLC and CLR 
                         processes, using CH4 as fuel, mixed or not, with H2O or CO2. The 
                         results showed the potential industrial applications of these 
                         materials, which are preferentially selective to the CLR process, 
                         and the addiction of H2O or CO2 greatly reduces the carbon
