Fast Pyrolysis of Rapeseed Oil in Presence of CuO Supported SBA-15 Catalysts

In this study SBA-15 based catalysts loaded with copper oxide were synthesized, characterised and investigated in fast catalytic pyrolysis of rapeseed oil using catalyst mixing method. Results of catalyst characterisation showed that all synthesised samples are mesoporous silica with uniform hexagonal shape cylindrical pores with space group P6mm and average pore size of 6 nm. Supported CuO did not influence the uniform hexagonal shape; however surface area and pore diameter decreased with increasing CuO loading. Investigation of fast pyrolysis of rapeseed oil shows that supporting with CuO suppresses the deoxygenation in form of H2O, CO and CO2 =regardless of the amount of CuO. At the same time supported CuO increased the content of oxygenates in the pyrolysis products = linearly to the CuO amount till 6-8% m/m of CuO. Further scale up the CuO content lowered the yield of oxygenates.
