Abstract

Supercritical water oxidation of isopropyl alcohol was investigated in a pilot‐scale reactor. A computational fluid‐dynamics model developed reveals the detailed flow field, chemical‐component distribution, temperature distribution, and salt‐particle trajectories in the reactor flow domain. The near‐wall fluid temperature from the numerical analysis was compared with experimental temperature data. The temperature comparison was within a 3% error band. The effect of the chemical kinetic rate was investigated for four different rates. Turbulent salt‐particle trajectories were also calculated to investigate the effect of particle sizes on salt deposit on the wall. Also, a method of calculating the adiabatic reaction temperature was developed to estimate reaction temperatures prior to a full numerical simulation.

The motivation for investigating the partial oxidation of propylene in sub‐ and supercritical water arises from the unique physico‐chemical properties of this medium. In sub‐ and supercritical water propylene oxide will react to 1,2‐propandiol, so this one‐step process would be an alternative for th
