Phosphate-based bifunctional catalysts for conversion of saccharides derived from biomass

Abstract

Alternatives that help reducing global dependence on non-renewable sources of carbon and energy are of great scientific and industrial interest. In this scenario, the lignocellulosic biomass has been receiving great attention, since it is a potential substitute for the production of chemical compounds of great industrial interest, obtained classically through non-renewable sources. In the chemical conversion of the biomass using acid catalysts, the cellulosic fraction can be converted into hydroxymethylfurfural (HMF) and the hemicellulosic fraction in furfural. Recent results show that the combination of Lewis acid catalysts and Brønsted acid significantly increase the rate of saccharide conversion and selectivity for the products. In this project, it is proposed the development of bifunctional Lewis acid and Brønsted acid catalysts based on phosphate compounds (metal phosphates, phosphate metal oxides and MAPOs) for the application in the conversion of saccharides derived from biomass.
