ULTRAPYROLYSIS OF WOOD BIOMASS FOR PRODUCTION OF ECOLOGICALLY CLEAN BOILER FUELS AND MOTOR FUELS

摘要

A fonned-layer based pyrolytic reactor, incorporating the counter flow of heated gas and the particles of raw waste wood, has been designed and constructed on a mobile platform. The basis of the design is a computer model (POLY.TERM 2), which calculates the gas and particle temperatures as they proceed from the opposing ends of the reactor, as a function of particle size and flow rates. The time of residence in the reactor, necessary to optimize the yields of biopetroleum (BPT) and fine charcoal (FCC), may be evaluated accordingly. Typical data are presented, based on preliminary results with wood chip fuel, a comparison between the theoretical and the experimental values being performed. The results of some early thermoliquefaction experiments are also included.
