Liquefaction of macroalgae Enteromorpha biomass for the preparation of biopolyols by using crude glycerol
Abstract
This article describes the liquefaction process of macroalgae Enteromorpha with the use of crude glycerol as a solvent and a reagent, aimed at obtaining of new bio-polyols, which are characterized with respect to their chemical structure, physical and thermal properties. Six different biopolyols were prepared. In order to optimize the liquefaction of algal biomass for the best bio-polyol properties, two catalysts (sulfuric or orthophosphoric acid) and three process temperatures (120–180 °C) were applied. Bio-polyol displaying the most advantageous properties (hydroxyl number 590 mg KOH/g and 86% biomass conversion) was obtained at 150 °C in the presence of sulfuric acid as a catalyst.
