| Outline of Final Research Achievements |
The use of lignocellulosic biomass for the production of energy and chemicals is one of the key issue of sustainable development. Biomass has high potential as renewable feedstock for the production of bulk chemicals, since it consists of highly functionalized molecules. The objective of our study of hydrothermal dissolution of biomass is the production of chemical feedstock with water and CO2.
Biomass hydrolysis experiments were conducted in a percolating reactor at 255°C with and without CO2. Liquid products yield with CO2 was much higher than that without CO2. After hydrolysis with diluted sulfonic acid of the liquid products, sugar yields increased with addition of CO2. We conclude that CO2 at supercritical condition catalyzes the hydrolysis of lignocelluosic biomass.
