Carbon capture and sequestration contains a group of technologies keeping the differentiation of CO2 from large industrial and energy related sources, transport to a storage location and long-term isolation from the atmosphere. Previous studies of CO2 adsorption on low-cost iron metal oxide surfaces strongly encourage the possible use of metal oxide as sorbents, but the tendency of magnetite particles to agglomerate causes a lowering of CO2 sorption capacity. This work investigates the adsorption behavior of CO2 on composite materials prepared coating a low-cost carbonized rice husk (cRH), commercial carbon black (CB) with magnetite fine particles. The CO2 capture capacity of composites and based on rice husk materials was evaluated the basis of the breakthrough times measured at atmospheric pressure and room temperature in a lab-scale fixed bed micro-reactor. To this aim the reactor has been firstly operated for CO2 adsorption data with obtained samples.
