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.
Abstract:
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.

본 발명은 연료의 열안정도를 향상시킬 수 있는 분산제와 이의 제조방법에 대한 것으로, 더욱 상세하게는 PIBSA(Polyisobutenyl succinic anhydride)에 아미노에테르기를 포함하고 있는 물질(2,2'-(Ethylenedioxy)bis(ethylamine), 1,11-Diamino-3,6,9-trioxaundecanyl-11-ol, 1-Amino-3,6,9-trioxaundecanyl-11-ol, 등)을 반응시켜 PIBSI 유도체를 제조하여 연료용 분산제로 활용하는 것에 대한 발명이다. 이를 이용하면, 액체연료(항공유, 경유, 휘발유)의 열산화반응에 의해 생성되는 탄소 침적물의 양을 보다 효과적으로 감소시킬 수 있다.
