Efficient dual-bed co-pyrolysis of lignocellulosic biomass and plastic to hydrogen-rich gas

Original language description

This work was focused on the development of dual-bed co-pyrolysis system consisting of thermal decomposition of biomass and plastic, initial upgrading of primary co-pyrolysis products into hydrogen-rich gas and further enrichment of gaseous products. The effect of the application of the catalysts and their arrangement have been investigated. The cellulose, spruce, and low-density polyethylene were used as feedstock. The obtained results revealed that hydrogen yield is strongly dependent on the location of catalyst beds. The highest H2 yield (25.6 mmol/g) was observed while the mixture of spruce and LDPE was initially decomposed at 500 degrees C and then directed to the 1st bed containing NiZr_red (material facilitating cracking and reforming of reaction intermediates formed during thermal treatment of the feedstock) and further to the 2nd bed containing CuFe_calc (mixed metal oxides catalyst improving the efficiency of water-gas shift reaction of primary gaseous products in the 1st bed). Both catalyst beds were heated to 700 degrees C. Performed experiments proved that an addition of polymer to biomass led to the significant improvement of H2 yield in comparison to decomposition of biomass alone (15.1 mmol H2/g). Moreover, the characterization of the spent catalysts confirmed that they remain stable in the reaction conditions.
