生物油含醛基和酚类化合物加氢脱氧热力学研究 Title:ThermodynamicStudyofHydrogenationand DeoxygenationofAldehyde-andPhenolic-ContainingBio-oils Abstract: Bio-oilsderivedfromrenewablebiomassresourceshave gainedconsiderableattentionasapotentialsubstituteforfossil fuels.However,thepresenceofaldehydeandphenolic compoundsinthebio-oilsleadstochallengesintheirstability, combustion,andupgradingprocesses.Inthisstudy,we investigatethethermodynamicsofthehydrogenationand deoxygenationreactionsofaldehyde-andphenolic-containing bio-oils,aimingtoprovideinsightsintothereactionmechanisms andoptimizetheconversionprocessestowardscleanerandmore efficientbio-fuels. Introduction: Bio-oilsareliquidfractionsobtainedfromfastpyrolysisof biomassmaterialssuchaswood,agriculturalwaste,andenergy crops.Althoughbio-oilshaveadvantagesofrenewabilityand potentialcarbonneutrality,theytypicallypossesshighoxygen content,whichresultsintheirpoorphysicalandchemical properties.Thepresenceofaldehydeandphenoliccompounds canbedetrimentaltotheirqualityandhindertheiruseasfuelsor feedstockforchemicalsynthesis.Therefore,understandingthe thermodynamicbehaviorsofaldehydeandphenoliccompounds duringconversionprocessesiscrucialforeffectivebio-oil upgrading. Methodology: Thehydrogenationanddeoxygenationreactionsofbio-oils werestudiedusingvariousexperimentaltechniquesand computationalmodeling.Initially,thebio-oilswerecharacterized todeterminethechemicalcomposition,includingthe concentrationofaldehydesandphenoliccompounds.Then,these compoundswereselectivelyextractedandpurifiedforfurther analysis.Thehydrogenationanddeoxygenationexperimentswere conductedundercontrolledconditions,includingthe temperature,pressure,andcatalysttype,whilemonitoringthe productdistribution.Thermodynamiccalculationswereperformed
