Abstract
The present invention relates to a process for liquefaction and saccharification of polysaccharide containing biomasses, having a relatively high dry matter content. The present invention combines enzymatic hydrolysis with a type of mixing relying on the principle of gravity ensuring that the biomasses are subjected to mechanical forces, primarily shear and tear forces. Furthermore, the present invention relates to the further utilization of such processed biomasses, e.g. for subsequent fermentation into bio-ethanol, bio-gas, specialty carbohydrates for food and fees as well as carbon feedstock for processing into plastics and chemicals.
Claims21
A process for liquefaction of polysaccharide containing biomasses comprising subjecting a polysaccharide containing biomass having a final dry matter content of between 20% and 40% and comprising lignocellulosic biomass to:
- a) enzymatic hydrolysis using at least one cellulase enzyme, and
- b) mixing by a free fall type mixing that provides mechanical degradation of the biomass during hydrolysis,
- wherein the biomass is changed to a more or less viscous liquid prior to further processing and
- wherein said further processing optionally includes fermentation.
