Abstract

A novel sorbent-enhanced biochar-direct chemical looping process is introduced for hydrogen production utilizing steam-iron reaction. ASPEN simulation was employed, performing a preliminary equilibrium analysis on the sorbent-enhanced biochar-direct iron oxide reduction. The effects of biochar and sorbent addition on the iron oxide reduction and reactor heat duty were investigated at different reactor temperatures. It is predicted that co-feeding of biochar and lime-based sorbents can significantly enhance the extent of iron reduction, while producing H2-rich syngas under a limited range of operating conditions. It was also observed that the proposed process can offer nearly autothermal iron oxide reduction at reactor temperature range of 650-700°C.
