The catalytic effect
of an SUS316 reactor surface on the hydrolysis
of benzamide in sub- and supercritical water was investigated at 350–450
°C and 25–65 MPa. Tube reactors having different surface
area to volume ratios were used to distinguish the effect of the homogeneous
reaction and the surface-catalyzed reaction. The surface of an SUS316
reactor acted as a heterogeneous catalyst for the hydrolysis reaction.
Kinetic analysis indicated that surface Fe<sub>2</sub>O<sub>3</sub> mainly contributes to the catalytic effect of SUS316. Both homogeneous
and surface-catalyzed reactions occurred, and the contribution of
each reaction depended on water density. The surface-catalyzed reaction
was dominant at low water density, and the contribution from the homogeneous
reaction became larger with increasing water density. Furthermore,
at 400 °C and 25 MPa, hydrolysis products promoted the reaction.
