This work shows and discusses the experimental results obtained from hybrid filtration combustion using biomass pellets originating from cereal plantations and forestry industry, which are some of the most common residual biomass sources in Chile. The biomass is made from oat cane, wheat cane, shining gum (Eucalyptus nitens) and insignis pine (Pinus radiata). The experiments were carried out using a porous media reactor filled with biomass pellets and alumina spheres in equal volumetric quantity. The gasifying agents used were a natural gas air mixture (equivalence ratio: Phi = 1.1) and an air-steam flow, in which the steam content varied from 20 to 40% of the initial air flow, changing filtration velocity from 26.1 to 31.3 and 36.5 cm/s, respectively. Using natural gas, temperature increased only using insignis pine while the usage of cereal plantation residuals enhanced syngas production. Maximum syngas production was achieved using wheat cane, obtaining 50% more H-2 and 97% more CO than the base line. Using steam, temperature of combustion was slightly influenced by a steam presence increase. Also, H-2 production was only enhanced when using wheat cane and insignis pine, while CO production was lower than the base line in every case. Maximum H-2 and CO production were obtained by the base line of shining gum, showing that the presence of steam disfavors syngas production in most cases.
