Esterification of biomass pyrolysis model acids over sulfonic acid-functional…

Abstract. Esterification of acetic acid with methanol, which was used as amodel reaction in the stabilization of biooil, was tested over propylsulfonic acid-functionalized SBA-15 materials. Due to the significant amount of water content in bio-oil, the water tolerance properties of the materials were also investigated in detail. The results showed that the functionalized mesoporous materials…
