Biomass Decomposition: A Study on the Effects of Organic Salt Promoted Hydrolysis on Cellulose
PúblicoOngoing research focuses on developing methods to improve the conversion of biomass into biofuels. Traditional mechanical pretreatment like ball-milling increases the cellulose reactivity, but cellulose re-crystallizes in water, making the process ineffective. The goal of the project was to explore Hofmeister series-based salts and analyze the salts’ effects on cellulose re-crystallization and subsequent glucose yields post hydrolysis. The experiment was carried out in two parts, the first with a salt selection containing fixed-anions (Cl-), the second with a salt selection containing fixed-cations (Na+). The salts’ ability to suppress crystallinity correlates with its performance in glucose yield, showing that the performance of salts agrees with the Hofmeister series. Specifically, salting-in salt such as guanidinium chloride gives highest yield while salting-out salt like ammonium chloride has the lowest glucose yield. The yield differences were attributed to their ability to suppress recrystallization.
