    Abstract

    The presence of metals and metal oxides decreases the autogenous ignition temperature (AIT) of hydrocarbons in the presence of high-pressure oxygen. In this study, the accelerating rate calorimeter (ARC), which can detect self-heating reactions as low as 0.03°C/minute, was used to study the interaction of selected metal oxides with a hydrocarbon oil in high-pressure oxygen at pressures up to 10.3 MPa. Hydrocarbon oil-metal oxide mixtures demonstrated self-heating reactions below the AIT of the hydrocarbon oil. Effects on peak self-heating rates and the temperatures at which self-heating occurred were also noted.
