Abstract:
PURPOSE: A liquid fuel composition is provided to improve the thermal stability of exo-tetrahydrodicyclopentadiene(exo-THDCP) by adding a thermal stabilizer into the exo-THDCP. CONSTITUTION: A liquid fuel composition includes exo-THDCP as liquid fuel and a thermal stabilizer. 0.1 to 5.0 weight% of one or more selected from tetrahydroquinoline, benzyl alcohol, and tetrahydroquinoxaline is added into the exo-THDCP as the thermal stabilizer. The tetrahydroquinoline is represented by chemical formula 2. In chemical formula 2, R1 is CH_2; n is 2 or 3; and R2 is H, CH_3, or C_2H_5. The tetrahydroquinoxaline is represented by chemical formula 4. In chemical formula 4, R1 is H, CH_3, or C_2H_5; and R2 is H, CH_3, or C_2H_5.

PURPOSE: A batch-type reactor for preventing the leakage of an internal pressure and an experimental method using the same are provided to maintain a pressure in the inside of a main body due to the deformation of a sealing unit generated at high temperature. CONSTITUTION: A receiving chamber receives a target which is capable of being heated based on heat at one end part of a main body(110). A cover(120) is mounted at another end part of the main body to cover an opening. A sealing unit is arranged between the cover and the main body to seal the receiving chamber. A cooling module is formed between the sealing unit and one end part of the main body in order to control the amount of heat transferred to the sealing unit.
Abstract:
PURPOSE: A carbon slurry fuel composition and a producing method thereof are provided to secure the excellent dispersion stability and mobility of a carbon solid particle. CONSTITUTION: A producing method of a carbon slurry fuel composition comprises the following steps: inserting liquid fuel, a carbon solid particle, and a surfactant into a mixing container; and stirring the added components. The surfactant is based on polysobutenyl succinimide, and is obtained by reacting polyisobutenyl succinic anhydride with amine.
