abstract = "Chemical-Looping Combustion (CLC) and Chemical-Looping Reforming
(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
deposition.",
