Supercritical Water Reformation of Crude Glycerol Solution for Hydrogen Production

Glycerol, also known as glycerin, is a less desirable byproduct formed in the production of biodiesel via the transesterification otriglycerides and presents a nontrivial issue in terms of developing other beneficial end uses. With an inflated glycerol market and rapidly increasing demand for the production of biodiesel, innovative utilization of the crude glycerol solution produced by biodiesel plants is paramount to the success of biodiesel as an alternative fuel. Supercritical water reformation of crudsolution presents a unique non-catalytic means of converting unwanted glycerol into hydrogen for use in energy and transportation applications, hence increasing the amount of usable transportation fuel that may be produced from triglycerides in biodiesel production. An ongoing experimental study of the supercritical water reformation of crude glycerol solution is being conducted to explore the effects of multiple variables important to the chemical reactions involved in the reformation process. Reaction variables include temperature, pressure, water-to-glycerol ratio, reactor space times, and the impact of other chemical species found in crude gycerol solutions, such as salts, alcohols, and soaps.
