Description

technical field [0001] The invention relates to a method for adiabatic calorimetry under high temperature and high pressure. Background technique [0002] To evaluate the thermal risk of a specific process, it is necessary to obtain parameters such as heat release rate, heat release, adiabatic temperature rise, and adiabatic pressure rise, and these parameters must be obtained through calorimetric testing. The modes of operation of the calorimeter include isothermal, dynamic and adiabatic. Commonly used calorimeters mainly include reaction calorimeter (RC1), accelerating rate calorimeter (ARC) and adiabatic calorimeter (Accelerating Rate Calorimeter and Method of Operation, US4208907), differential scanning calorimeter (DSC), etc. [0003] For the calorimetric test for the purpose of process thermal risk assessment, the following conditions are often required: 1) The sample size is large enough to reduce the influence of the amplification effect; 2) Because the adiabatic mo...
