Abstract
The present work concerns the co-gasification of crude glycerol (CG), a by-product of biodiesel industry, with locally available lignocellulosic biomass aiming at the production of syngas and further promotion of power production in dedicated bioenergy units. Co-gasification of CG with olive kernel (OK), an agro-residue issued from the intensive olive oil production sector in Southern East Europe, was performed in a laboratory fixed bed reactor at T=750–850οC with λ=0.2–0.4 and in the three different mixing levels of 24wt%, 32wt% and 49wt% of CG in OK. Co-gasification of CG with OK found to favor the gas yield which increased from 0.4 to 1.2Nm3/kg for the mixture of 49wt% of CG in biomass. Additionally H2 concentration increased from 19 to 33%(v/v) in the gasification gas while the tar yield decreased from 19.5 to 2.4wt% at conditions of T=850οC and λ=0.4.
