    21st World Hydrogen Energy Conference (WHEC), Zaragoza, SPAIN, JUN 13-16, 2016The autothermal Chemical-Looping Reforming (a-CLR) is a process where syngas is produced with two main advantages; there are captured CO2 emissions and the heat required for the syngas production is generated by the process itself. A Ni-based material is used as oxygen carrier circulating between two fluidized bed reactors: the fuel and air reactors. In this work, the auto-thermal conditions in a global H2 production process, integrated by the a-CLR process and a Water Gas Shift reactor, using different liquid fossil fuels were theoretically determined. The hydrogen production per mol of carbon in the fuel was similar for all fossil fuels, taking a value of 2.2 at the optimal operating temperature (700 °C). In addition, the possibility of working at low temperature for a maximum H2 production was experimentally demonstrated in a continuous 1 kWth a-CLR unit.This work is partially supported by the Spanish Ministry for Science and Innovation (MICINN project ENE2011-26354), by European Regional Development Fund (ERDF) and by the Government of Aragón (Spain, DGA ref.
