| Outline of Final Research Achievements |
For a packed bed reactor, which consists of a 1/2-inch stainless steel tube filled with alumina particles having the diameter of 3 mm, the flow behavior of heavy oil in the reactor under the atmosphere of nitrogen gas or supercritical water was observed by neutron radiography. In the heavy oil/nitrogen gas system, the effect of reactor temperature on the flow behavior at atmospheric pressure was clarified. Particularly, the flow channeling was observed in the reactor at a relatively high temperature. In the heavy oil/supercritical water system, the effect of flow rate of heavy oil on the flow behavior was investigated at 400℃ and 25 MPa. Through this work, it was revealed that neutron radiography is a useful technique to visualize the flow behavior of heavy oil in a packed bed reactor, whose wall was made of metal, at high temperature and high pressure.
