疏水改性ZSM-5对双功能催化剂NaFe/ZSM-5催化CO2加氢制绿色航空煤油性能的影响
Influence of ZSM-5 after hydrophobic modification on catalytic performances of NaFe/ZSM-5 for CO2 hydrogenation to sustainable aviation fuels
摘要
Abstract
CO2 hydrogenation to sustainable aviation fuels can not only help achieve"carbon neutrality",but also support the sustainable development of the aviation industry.However,due to the difficulty in activating CO2 as an inert molecule and the difficulty in generating sustainable aviation fuels(C8～C16 hydrocarbons)by C—C coupling,catalyst design has faced significant challenges.Propyl trimethoxysilane(PTMS)was used to modify ZSM-5 zeolites,and ZSM-5 zeolites with varying water contact angles were successfully prepared after hydrophobic modification.They were combined with Na-Fe3O4 to construct bifunctional catalysts for CO2 hydrogenation.The results show that propyl trimethoxysilane modification can not only enhance the hydrophobicity of ZSM-5 zeolites,but also inhibit the cracking of long-chain hydrocarbons on the surface of ZSM-5 zeolites to improve the sustainable aviation fuels selectivity by the acidic sites coverage on the outer surface of ZSM-5 zeolites with hydrophobic groups.Under the reaction conditions of 320℃,3 MPa and n(H2):n(CO2)=3:1,NaFe/Z5-0.5PTMS has the best catalytic performance for CO2 hydrogenation,with the CO2 conversion rate of 32.6%,CO selectivity of 9.9%and sustainable aviation fuels selectivity of 38.8%.关键词
