摘要
为了扩大喷气燃料的原料来源,减少温室气体排放,生物喷气燃料制备技术的开发受到许多国家的重视。生物喷气燃料是用可再生动、植物油或生物质原料生产的喷气燃料,其制备技术主要有4类路线。第一类是以动、植物油为原料,经加氢处理和异构化生产喷气燃料。第二类是以农林废弃物等生物质为原料,先气化生成合成气,再经费-托合成生成合成油,合成油再经加氢改质得到喷气燃料。第三类是以生物质为原料,先经快速热解生成生物油,生物油再经加氢处理生成喷气燃料。第四类是以生物质为原料,通过微生物发酵转化为生物丁醇,生物丁醇脱水生成丁烯,丁烯再经聚合、加氢也可生产生物喷气燃料。生物喷气燃料无硫、无芳烃,是绿色喷气燃料调和组分。
To reduce the emission of greenhouse gases and broaden the raw material sources of jet fuel, many countries have focused on accelerating the development of bio-jet fuel. There are four routes to produce bio-jet fuel from vegetable oil, animal fat and biomass. The first method is two-stage hydrogenation route which includes the step of hydrotreating vegetable oil or animal fat and the followed step of hydroisomerization and selective cracking. The second type of technology uses biomass as feedstock and produces bio-jet fuel by gasification and synthesis. The third method is biomass pyrolysishydro-upgrading technology. In this process, the pyrolysis oil is derived from the fast pyrilysis of biomass, and which is treated by dual stage deoxygenation to generate a partially deoxygenated product. The deoxygenated product comprises cyclic hydrocarbon compounds that when fractionated are useful as bio-jet fuel. The other route is bio-butanol conversion method using biomass as feedstock, which includes the steps of fermentation, dehydration, oligomerization and hydrogenation. Being aromatic-free and sulfur-free, the bio-jet fuel is a green fuel for use as blending components with normal jet fuel.
