The device and method are provided 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 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 another feature of our technology. This system condenses bio-oil pyrolysis vapors to various desired fractions by differential temperature manipulation of individual condensers comprising a condenser chain.

Method of increasing anhydrosugars, pyroligneous fractions and esterified bio-oil

The proposed invention comprises a highly elastic sealing cover for covering food containers or dishes. It is capable of replacing existing rigid covers or plastic wrap/aluminum foil. The elastic nature and design of the proposed invention allow it to provide a more air-tight seal than plastic wraps or aluminum foil on a wide range of sizes and shapes of dishes or other food storage items. It can also conform to objects bulging out of containers (i.e., a head of lettuce).
