Biomass pyrolysis coupled with non-thermal plasma/catalysis for hydrogen production: Influence of biomass components and catalyst properties

A novel two-stage pyrolysis-plasma/catalysis process has been developed for hydrogen production from waste biomass. Investigation into; the comparison of biopolymers, cellulose and lignin; effect Mg, Co, Ce, Cu, Fe Ni as promoter metals added to a Ni-Al2O3 catalyst; influence catalyst support material in relation was carried out. The combination plasma catalysis produced highest total gas yield processing biomass non-plasma pyrolysis-catalysis. 4.07 mmol g−1 compared with lignin which 4.29 hydrogen. Metal promoters Ni-alumina did not have strong on production. However, some catalysts (Cu-Ni-Al2O3 Ni-Ni-Al2O3), showed that addition metal resulted reduced order terms (H2 biomass) was, Ce-Ni > Co-Ni Mg-Ni Fe-Ni Ni-Ni Cu-Ni. In addition, different materials were investigated. Hydrogen alumina titanium oxide Y-zeolite supports. linked surface area porosity, dielectric constant material.
