Исследование паровоздушной конверсии древесного угля методом термогравиметрического анализа

Abstract

The thermogravimetric analysis was used to study the conversion of charcoal in flow of air, steam, and air-steam mixture at 800 ° C. The composition of the conversion products was obtained using a mass-spectrometer. For individual particles ranging in size from 3 to 18 mm, the conversion rate in an air-steam mixture is higher than in air. For a bed of 0-200 μm parti-cles, the addition of steam to the air blast causes a reduction in the conversion rate.
