Method of increasing anhydrosugars, pyroligneous fractions and esterified biooil
Abstract
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 biooil pyrolysis vapors to various desired fractions by differential temperature manipulation of individual condensers comprising a condenser chain.

Mechanical method for separating fractions of incinerated urban refuse or similar industrial refuse
A method is disclosed for separating fractions of incinerated refuse with a high recuperation yield without requiring special equipment. A first portion of the separation process may be applied to either an initially dry or an initially wet refuse. The refuse is at first screened to a median size. The oversized fraction is crushed and shredded and the nonmagnetic fraction separated therefrom is sent commonly to a grindingrolling mill which also receives the undersize fraction. The undersize fraction downstream of the grinding mill is further treated by a wet separating process, the method achieving separation of ferrous and nonferrous metals,more » 
Method and apparatus for probing relative volume fractions
A relative volume fraction probe particularly for use in a multiphase fluid system includes two parallel conductive paths defining therebetween a sample zone within the system. A generating unit generates time varying electrical signals which are inserted into one of the two parallel conductive paths. A time domain reflectometer receives the time varying electrical signals returned by the second of the two parallel conductive paths and, responsive thereto, outputs a curve of impedance versus distance. An analysis unit then calculates the area under the curve, subtracts the calculated area from an area produced when the sample zone consists entirely ofmore »
