The gasification of isooctane, a model compound of gasoline, was carried out in supercritical water to produce hydrogen in a continuously operated tubular reactor. The influences of feed inlet temperature, residence time, reactor temperature, feed concentration and oxidant concentration were examined in detail at a fixed pressure of 25 MPa. Hydrogen peroxide was used as the oxidant. The major components of the produced gas were H2, CH4 and CO2 and the minor components of the produced gas were CO and C2H6. As residence time, isooctane concentration, and reactor temperature increased, H2, CH4, and CO2 gas yield increased while CO gas yield did not change much. Possible reaction pathways at each experimental condition are presented. |
