	Supercritical water oxidation represents an innovative
	technology for complete and efficient destruction of
	hazardous wastes, without forming of harmful by-products.
	Organic compounds and oxygen are completely soluble in
	supercritical water at temperatures above 374 deg C and
	pressures above 221 bar, providing a single-phase medium
	for rapid oxidation of organic to C02, H20, and N2. The
	scale-up and reliable operation of commercial-sized
	process equipment require a thorough understanding of
	oxidation kinetics, reaction pathways, and mechanisms.
	Glucose (C6H1206) hydrolysis and oxidation were done in
	collaboration with Richard H. Holgate. Experiments were
	done in an isothermal, isobaric, tubular plugflow reactor
	apparatus. Both hydrolysis and oxidation occurred rapidly
	in supercritical water at 246 bar. A diverse set of
	products, present in the liquid effluent and also subject
	to hydrolysis, was formed. At 600 deg C and a 6-second
	reactor residence time, glucose is completely gasified,
	even in the absence of oxygen. In the presence of oxygen,
	destruction of liquid- phase products is enhanced, with
	none found above 550 deg C at a 6-second reactor
	residence time. Major products formed were acetic acid,
	acetonylacetone, propenoic acid, acetaldehyde, carbon
	monoxide, methane, ethane, ethylene, and hydrogen.
	Methane and hydrogen were present at temperatures up to
	600 deg C for reactor residence times of 6 seconds.
