Research on the Preparation of High-density Hydrocarbon Fuels Based on Biomass
Biomass based high-density aerospace fuels are of great significance for ensuring national energy security.This article uses Ru/HZSM-5 bifunctional catalyst and guaiacol as the model compound to prepare cycloalkanes through hydrogenation deoxygenation reaction.The effects of reaction time,temperature,and acidity of zeolite molecular sieve carrier on the reaction were investigated.It has been proven that the suitable reaction conditions are HZSM-5 Si/Al value of 50,reaction time of 2 hours,and reaction temperature of 230℃.The conversion rate of guaiacol hydrogenation deoxygenation reaction exceeds 99%,and the selectivity for cycloalkanes is 99.2%.
