I have learnt from many articles about biomass conversion. All are using a pressure autoclave or microwave reactor. Is the reaction not possible in a glass batch reactor?
As it is evident from various research that biomass is a very complex composite of cellulose, hemicellulose and lignin. Furthermore a deeper sight in individual component can give a clear view on structural complexity. So to convert biomass either in composite form or in individual form require high energy in the form of temperature, pressure autoclave or microwave reactor. Although recent research emphasize more on use of condition closer to ambient through the use of various solid catalysts. So in near future we can expect simpler reaction condition which will convert biomass efficiently to various chemicals and energy.
The main advantage to use microwave as heat transfer media is the efficiency, if you use a glass, the radiation of microwave will transfer directly to the biomass, but if your use a white body (porcelain crucible) the microwave will be adsorbed for the body and the transfer to the biomass (into the crucible) will be by conductivity heat transfer.
