CO-PROCESSING CONCEPTION OF A QUENCHING PLASMA REACTOR ASSOCIATED TO A FLUIDIZED-BED DESIGNED TO HYDROGEN RADICAL PRODUCTION AT LOW-TEMPERATURES

The aim of this paper is to present a new way to produce a high flow o f hydrogen radical, at low temperatures. Thirst, an atmospheric pressu re plasma of an argon-hydrogen mixture generates a high flow of hydrog en radical at temperatures up to 5000 K. The applications of these rad icals, in such conditions, are limited by thermal aspects which are ob viously different from classical reactions of hydropyrolysis or other treatment processings of organic molecules. Our approach is to quench the plasma by a fluidized bed reactor which transport properties are c ompatible with plasma phase ((1)). From this point of view, the plasma /fluidized bed system is qualified in terms of its thermodynamic and h ydrodynamical properties and its quenching velocity. The atomic hydrog en flow generated within such conditions is calculated and then experi mentally measured.
