Combustion of Activated Carbon Particles Part.1: Experimental Investigation of the Two Distinctive Burning Modes in A Packed Bed

Features of one-dimensional combustion-wave propagation of activated carbon particles (~ 1mm) packed in a quartz tube was examined experimentally. Rich oxygen was introduced into the tube to promote the surface oxidation of the activated carbon particles. An oxidizing mixture flows through a vertically placed quartz tube (from bottom to the top). Followed by the ignition at the top, hot reactive zone propagates downwardly with negligible...
