Catalytic Pyrolysis of Wood by Presence of Clay Minerals

Abstract

Devonian, and Quaternary clays of Latvia together with additive of sawdust after plastic moulding of pellets were used. Partial oxidation of sawdust and formation of active carbon after thermal shock at temperature 800°C were determined. The main clay mineral in all of clays was hydromica with some difference in the structure. Obtained materials with bulk density 1.1 g/cm3 as sorbent for different chemicals such as iodine and methylene blue was used. Dependence of sorption ability of pellets on the type of used clay (clay minerals) was determined. XRD for the determination of phase compositions, nitrogen absorption for the pore size distribution, SEM for the analysis of structure and nanoscale Zetasizer for the determination of surface charge were used.
