New progress was made in the research of lignocellulose high-density aviation biofuel in Dalian Chemical Institute
Recently, the team of Li Ning, a researcher in the aerospace catalysis and new materials laboratory of the Dalian Institute of Chemical Physics, the Chinese Academy of Sciences, and the team of Zhang Tao, an academician of the Chinese Academy of Sciences, have collaborated with the team of Lu Fang, a researcher from the Department of Bioenergy Research of the Dalian Institute of Chemical Physics, and Zou Jijun, a professor at the School of Chemical Engineering, Tianjin University. Based on the study of material conversion, the first report of the two-step conversion of cellulose into high-density liquid fuel. Related work was published in Joule. As a renewable carbon resource, lignocellulose is very important to ensure the energy security of our country and the reduction of carbon dioxide emissions in our country. In this work, researchers reported for the first time a method for converting inedible cellulose into high-density aviation kerosene: First, a hydrogenolysis reaction was used to convert cellulose to 2,5-hexanedione with high selectivity, And through the method of reaction separation, the final carbon yield of 2,5-hexanedione was 71.4%; subsequently, a two-bed catalytic system was adopted to react 2,5 -Conversion of hexanedione to C12 and C18 polycycloalkane fuels with branched chain structure with a carbon yield of 74.6%. The polycyclic alkanes obtained by this process have the characteristics of high density (0.88g / mL) and low freezing point (225K). In practical applications, the product can be used alone as a high-density advanced aviation fuel; it can also be used as a fuel additive to increase the volumetric heating value of aviation kerosene. The above research work was supported by the National Natural Science Foundation of China, the Chinese Academy of Sciences Clean Energy Innovation Research Institute Cooperation Fund, the Chinese Academy of Sciences ’Strategic Leading Science and Technology Project, the National Major R & D Program, and the Energy Materials Chemistry Collaborative Innovation Center of the Ministry of Education.
