Observation of the Heavy Crude Oil Dissolution Behavior Under Supercritical Condition of Water

In development of on-site partial upgrading technology of the bitumen by using supercritical water as a reaction solvent, it is<br>important to understand the role of water in the reaction field. Therefore experiments were carried out using a batch reactor<br>system operating with varying reaction pressure at a temperature of 703 K, and reaction time of 15 min. From the results such<br>as the viscosity and the boiling point distribution of oil product etc., it can be seen that higher density supercritical water<br>inhibits the cracking of bitumen to lower molecular weight substance.
