The conversion of green, cheap and renewable biomass materials into biofuels through thermochemical and biochemical methods is one of the key route to provide sustainable energy in future. The introduction of ultrasonic energy in biomass conversion could destroy the recalcitrance structure of lignocellulosic biomass at room temperature, facilitate the separation of complicated composition in raw materials, turn heterogeneous reactions into homogeneous or at least quasi- homogeneous reactions, and therefore essentially remove barriers that limited the efficiency and selectivity in biomass conversion. （更多…）

通过热化学和生物化学方法将绿色廉价、可再生的生物质原料转化为燃料是解决未来能源困境的重要途径。使用超声波能量实施过程强化，可以在室温条件下破坏顽抗的生物质结构，便利复杂化学组分的分离，将生物质的催化反应由非均相转变为均相或者准均相，从而在本质上改善制约生物质转化效率和选择性的因素。超声波具有特殊的物理特性，可以通过空化作用积累超声能量，然后通过空化气泡在微秒数量级的瞬间崩溃急剧释放能量。释放的能量强度足以破坏任何的化学键，打破多相体系的界面限制，强化反应过程的传质传热。因此，超声波处理既可以高效地破坏生物质结构，促进生物质原料的混合和反应，又不至于显著影响生物质反应的选择性，在生物燃料领域的研究中具有较大潜力。 （更多…）

随着化石燃料的逐渐枯竭与能源需求的不断增加，人们越来越认识到寻求能源替代品的迫切性，所以国内外研究者纷纷开展农业废弃物转化成高附加值产品的研究。马来西亚是种植棕榈油料植物最多的国家之一，随着棕榈油的广泛开发利用，棕榈油厂每年生产大约2.39万吨棕榈果实残渣废弃物，经过研究表明其残渣中不仅含有蛋白质，而且其水解产物含有甘露糖，葡萄糖和半乳糖等六碳糖，为微生物发酵生产高附加值化学品提供了较为理想的碳源，使其有可能成为马来西亚棕榈油工业的副产品开发方向。 （更多…）

Climate change together with the increased concern for the energy security has imparted a trend shifting on the use of fossil fuels to renewable energy sources. Worldwide attention has been focused on the transforming of agricultural waste into high value-added products. Malaysia, one of the global leading palm oil producers, seeking a next catalyst for sustaining economic growth since the palm oil production has reached a mature stage. Palm kernel cake (PKC), one of the main by-products from palm oil industry, is rich in protein (14.5 – 19.6%) and mannan (35.2%). （更多…）
