反应温度对催化柴油制高能量密度燃料烃类组成的影响
Influence of reaction temperature on hydrocarbon composition of high-energy-density fuels derived from catalytic diesel
摘要
Abstract
In response to the challenge of high-value utilization of catalytic cracking diesel containing polycyclic aromatic hydrocarbons,the regulation of reaction temperature in the deep hydroconversion of polycyclic aromatic hydrocarbons-rich catalytic cracking diesel for high-energy-density fuel production were investigated.Experiments were conducted on a two-stage fixed-bed pilot plant at 18 MPa,0.4 h-1,and a hydrogen-to-oil volume mass ratio of 800∶1 L/kg,examining different temperature combinations between 330-380℃.The results show that a cascade temperature strategy(340℃in the first reactor and 360℃in the second)achieves＞97％aromatics saturation and＞99.9％removal of sulfur and nitrogen.The hydrogenated product composition is 13.34％paraffins,38.67％monocycloalkanes,44.24％dicycloalkanes,1.43％tricycloalkanes,and 2.32％arenes.The resulting 188-270℃aviation kerosene fraction exhibits superior properties-density(0.835 g/cm3),crystallization point(＜-68 ℃),aromatics mass fraction(2.35％),and heating value(46.32 MJ/kg).All these values exceed the requirements the GJB 209629-2019 standard.This work demonstrates that precise temperature control enables directional conversion of catalytic cracking diesel into high-energy-density fuel,offering a reliable technical pathway for its value-added utilization.关键词
