以日本山毛榉（FaguscrenataBlume）为原料，采用间歇式反应器，研究了不同直链醇在亚临界和超临界状态下的液化反应。在270 ℃的反应条件下，山毛榉木材在所有醇类中均有一定程度的液化，处理30 min后约有50%~ 65%的不溶物残留;而在350 ℃的反应条件下，90%以上的木材在所有醇类中分解液化。具有较长烷基链的醇在较短反应时间内液化木质纤维素。由于生物质可以生产甲醇、乙醇等多种醇类，因此利用生物质醇类可以通过超临界醇类技术制备100%的生物质基液体燃料。
The liquefaction of Japanese beech (Fagus crenata Blume) was studied with various straight-chain alcohols in suberitical and supercritical states using a batch-type reaction vessel to obtain liquid fuel from lignocellulosics. Under the reaction condition of 270 degrees C, beech wood was liquefied to some extent in all alcohols with about 50%-65% insoluble residue left after treatment for 30 min. Under the condition of 350 degrees C, however, more than 90% of wood was decomposed and liquefied in all alcohols. Alcohols with longer alkyl chains liquefied lignocellulosics in shorter reaction times. Because many kinds of alcohols, such as methanol and ethanol, can be produced from biomass, 100% biomass-based liquid fuel can be prepared by supercritical alcohol technology when using such bioalcohols.
