Abstract:
Recently liquefaction has been an important way of using biomass raw material.In order to enhance the additional value of soybean dregs，the single factor experiment and the orthogonal test has been used to study the soybean dregs phenol liquefaction craft，liquefaction production is prepared for wood adhesive.Under the effect of sulfuric acid catalytic，the soybean dregs could be liquefied well in the phenol.Among the four influncing factors of soybean dregs phenol liquefaction，catalyst had the most remarkable impact，then were the fluid ratio，the liquefaction time and the temperature.Within the scope of the experiment parameter that choiced，when the fluid ratio and the catalyst amount used were higher，the residual rate is lower，in other words the liquefied efficiency is higher.The optimal craft of soybean dregs phenol liquefaction was reacting at 150℃ for 1.5 h with 4:1of the phenol to soybean dregs mass ratio and 10% catalyst.Under this craft condition，the liquefation efficiency reached 97.3%.
