Accelerating Rate Calorimeter

The adiabatic acceleration calorimeter (ARC) is a high-precision instrument used to study the thermal runaway behavior of chemical reactions,

By simulating an adiabatic environment (without heat loss), measure the temperature of a chemical substance or reaction system during self heating

Pressure changes are used to evaluate thermodynamic (such as reaction heat) and kinetic (such as activation energy, reaction rate) parameters.

Its core value lies in quantifying the risk of hot air in chemical processes, providing key data support for process safety design and accident prevention.

working principle

The core insulation principle of ARC is to dynamically track the sample temperature and adjust the instrument environment temperature in real time, ensuring no heat exchange between the sample and the external environment (adiabatic conditions). When the sample releases heat due to a chemical reaction, the instrument will immediately increase the ambient temperature synchronously, eliminating the temperature difference between the sample and the environment (AT ≈ 0), thus simulating the conditions in industrial scenarios where heat cannot be dissipated (such as cooling failure or material accumulation), and truly reflecting the dynamic behavior of sample self heating.
