dc.description.abstract | The three reactor chemical looping process (TRCL) for the production of hydrogen from natural gas is quite attractive for both CO2 capture and hydrogen production The TRCL process consists of a fuel reactor a steam reactor and an air reactor In the fuel reactor natural gas is oxidized to CO2 and H2O by the lattice oxygen of the oxygen carrier In the steam reactor the steam is reduced to hydrogen through oxidation of the reduced oxygen carrier In the air reactor the oxygen carrier is fully oxidized by air In this process the oxygen carrier is recirculated among the three reactors which avoids direct contact between fuel steam and air In this study various candidate materials were proposed for the oxygen carrier and support and a thermal analysis of the process was performed The oxygen carrier for the process must have the ability to split water into hydrogen in its reduced state which is a different chemical property from that of the chemical looping combustion medium The selection of the oxygen carrier and support require careful consideration of their physical and chemical properties Fe2O3 WO3 and CeO2 were selected as oxygen carriers Thermal analysis indicated an expected hydrogen production of 2 64 mol H-2 per mol CH4 under thermoneutral process conditions The results indicated that hydrogen production was affected mainly by the steam conversion rate The solid circulation rate and temperature drop in the fuel reactor were calculated for the selected oxygen carriers with different metal oxide contents and solid conversion rates (C) 2010 Professor T Nejat Veziroglu Published by Elsevier Ltd All rights reserved | - |
