Abstract

Studies of the effect of microwave (MW) pretreatment on the pyrolysis of ferulic acid (FA), as a model compound of lignin, on the CeO2 surface are essential for understanding the prospects for the use of MW in catalytic pyrolytic technologies for the processing of lignocellulose. In this work, FT-IR spectroscopic studies of MW-pretreated samples of FA on the nanoceria surface were carried out. Their pyrolysis was studied by temperature-programmed desorption mass spectrometry (TPD MS). It was found that monodentate carboxylate complexes of FA are most susceptible to the influence of MW. MW-pretreatment for 300 s during pyrolysis of FA on the CeO2 surface leads to a decrease in the content of 4-vinylguaiacol in the final pyrolysis products. Phenolate complexes, as well as bidentate carboxylate complexes of FA on the CeO2 surface are less sensitive to MW. The use of MW-pretreatment promotes an insignificant decrease in the formation of polyaromatic compounds during the FA catalytic pyrolysis.
