Title:
METHOD OF INCREASING ANHYDROSUGARS, PYROLIGNEOUS FRACTIONS AND ESTERIFIED BIO-OIL
Document Type and Number:
WIPO Patent Application WO/2011/041756
Kind Code:
A3
Abstract:
The device and method of this invention provides a means to increase anhydrosugars yield during pyrolysis of biomass. This increase is achieved by injection of a liquid or gas into the vapor stream of any pyrolysis reactor prior to the reactor condensers. A second novel feature of our technology is the utilization of sonication, microwave excitation or shear mixing of the biomass to increase the acid catalyst rate for demineralization or removal of hemicellulose prior to pyrolysis. The increased reactivity of these treatments reduces reaction time as well as the required amount of catalyst to less than half of that otherwise required. A fractional condensation system employed by our pyrolysis reactor is also a novel element of our technology. This system condenses biooil pyrolysis vapors to various desired fractions by differential temperature manipulation of individual condensers comprising a condenser chain.
