Prediction of the ideal maximum operational temperature of hydrocarbon and HFCs as working fluids of organic Rankine cycle power plants based on transition state theory

The use of organic working fluids in organic Rankine cycle (ORC) power plants may lead to thermal decomposition, which can negatively impact system performance and safety. Therefore, it is essential to determine the safe operating temperature range of the working fluids. In this paper, a simplified theoretical method based on the transition state theory is proposed to predict the ideal maximum operational
