  • Radiant flash pyrolysis of cellulose - evidence for the formation of short life time liquid species and experimental determination of mass balances

Abstract

The purpose of the present paper is to report some of the first results of the radiant flash pyrolysis of cellulose pellets. The experiments are made under controlled and very clean conditions of fluxes and controlled irradiation times with an image furnace. The flux densities that can be obtained reach about 2 10(7)Wm(-2) while the irradiation times are of a few milliseconds. The microscopic observations of the surface of the pellets after irradiation show that cellulose gives rise to intermediate species that are liquid at the temperature of reaction. They are solid at room temperature and soluble in water. The experimental mass balances show that these liquids undergo fast thermal decompositions into vapours, with no noticeable formation of char.
