It is noted that the sensitivity of temperature on the coke formation rate is higher than the initiator sensitivity for a similar range of the conversion change. The endothermic heat sink capacity of the H‐Carene increased by about 28% at 650☌ with 5% (by weight) of TEA. The investigation showed that the initiator improved the fuel conversion and endothermicity. The aptness of triethylamine (TEA) as an initiator to improve the heat sink capacity of the H‐Carene fuel is also examined. At 650☌ and 40 bar pressure, the conversion of the H‐Carene fuel is about 40%, and the estimated value of chemical heat sink capacity is 488 kJ/kg of fuel. The experiments were performed for a wide range of temperatures between 450☌ and 650☌ at 40 bar pressure in a tubular flow reactor. The thermal cracking characteristic of an in‐house prepared plant‐derived hydrogenated carene (H‐Carene) fuel is examined above its critical temperature and pressure. Due to the advantages of high power generation efficiency and specific work, hybrid system is a competitive power generation system in aviation field. In addition, the parameters such as pressure ratio, temperature ratio and fuel utilization have important influence on the performance. And the specific work of the hybrid system with exhaust recirculation can reach more than 760 kW (kg air)⁻¹. But the ACRHS shows greater potential in increasing the SOFC cathode inlet temperature. The results show that the power generation efficiency of the BHS is 59.3%, while the two hybrid systems with exhaust recirculation increase to around 70%: the efficiency of ARHS is 70.9%, and ACRHS is 69.7%. And the performance of three configurations of hybrid system without/with SOFC exhaust recirculation are compared and evaluated, which are a basic hybrid system without exhaust recirculation (BHS), an anode exhaust recirculation hybrid system (ARHS), and an anode and cathode exhaust recirculation hybrid system (ACRHS). In this paper, the advanced solid oxide fuel cell gas turbine hybrid power generation system based on aviation kerosene is studied.

Developing aviation power generation methods with high efficiency is one of the important issues that need to be solved in aviation field, especially for More/All Electric aircraft.
