| 英文摘要 | bagasse was subjected to a liquefaction process with polyethylene glycol/glycerol using sulfuric acid as catalyst. the effects of various liquefaction conditions, such as reaction time, liquefaction temperature, catalyst content, and liquid ratio (liquefaction solvents/bagasse), on the liquefied residue (lr) content and hydroxyl and acid numbers of liquefied products were investigated. the preferred liquefaction condition of bagasse was determined through orthogonal experiments. the results showed that the catalyst content and reaction time have a greater influence than liquid ratio and liquefaction temperature on the percentage of lr. the hydroxyl and acid numbers of the liquefied products were influenced by many factors, including liquefaction temperature, reaction time, acid content, and liquid ratio. the hydroxyl number of liquefied products decreased as the liquefaction reaction progressed, but the acid number of liquefied products increased. based on the obtained data, the kinetics for liquefaction was modeled using the first-order reaction rate law and the apparent activation energy for the liquefaction of bagasse was estimated to be 38.30 kj mol(-1). |
