Glycerol is a less desirable byproduct formed in the production of biodiesel via transesterification of triglycerides and presents a nontrivial issue in terms of developing other beneficial end uses. Supercritical water reformation of glycerol presents a unique non-catalytic means of converting unwanted glycerol into hydrogen for use in energy applications, hence increasing the amount of usable transportation fuel that may be produced from triglycerides in biodiesel production. The effect of space time was evaluated on the non-catalytic reformation of glycerol in supercritical water. An experimental study was conducted using a 0.4-L Haynes Alloy 230 reactor at a constant pressure of 22.4 MPa. The space time was varied between 30 and 160 seconds with temperatures ranging from 500 to 700¢ªC and water to glycerol ratios ranging from 6:1 to 12:1.
