摘要

Catalytic hydrogenation of cellulose in a straight-chain aliphatic hydrocarbon solvent for converting cellulose to hydrocarbons was investigated.Thermally stable hydrocarbon solvents suppress condensation reactions unlike hydrogen-donor solvents,such as alcohol.In addition,hydrogen transfer from a hydrocarbon solvent to cellulose-derived oxygenates is possible when the solvent is used with a hydrogenation catalyst,such as palladium on activated carbon(Pd/C).Moreover,cellulose-derived oil(bio-oil)can be directly used as a transportation fuel without removing the solvent.Although the bio-oil yield is high,the use of Pd/C increases the production cost.Therefore,nickel on activated carbon(Ni/C)was employed as a low-cost catalyst in this study to investigate catalytic hydrogenation of cellulose.In the Ni/C-containing solvent,the cleavage of the C-0 bond in cellulose was promoted,resulting in the production of levoglucosan and 5-hydroxymethylfurfural.Similar to Pd/C,the use of Ni/C led to hydrogen transfer from the solvent to oxygenates at>300 ℃ and the production of cellulose-derived hydrocarbons.However,the hydrocarbon yield decreased when the reaction occurred at 400。C because the reaction products over-decomposed to hydrocarbon gas and polymerized to heavy oil.Therefore,a reaction temperature of 350 ℃ was noted to favor the production of cellulose-derived hydrocarbons.
