The energy requirements associated with conventional mechanical size reduction of poplar and aspen wood are compared to a new method of size reduction employing a wood planer. Although the planer requires about 2.3 times less energy to achieve the same size reduction as conventional methods, large-scale equipment to implement this approach does not currently exist. Explosive depressurization was also compared to conventional mechanical size reduction. The conventional mechanical methods require roughly 70% more energy to achieve the same size reduction as explosive depressurization. Thus, explosive depressurization appears to be the preferred method and has the added benefit of altering the chemical structure of the wood to enhance the enzymatic hydrolysis of the cellulose fraction.
将杨树和白杨木材进行传统机械减小尺寸所需要的能量与一种使用木刨床的新减小尺寸方法进行了比较。虽然该刨床所需的能量大约是传统方法的 2.3 倍,但目前还没有实施这种方法的大型设备。还将降压爆破与传统机械减小尺寸进行了比较。传统的机械方法需要大约 70%更多的能量才能达到与降压爆破相同的减小尺寸效果。因此,降压爆破似乎是首选方法,并且还有额外的好处,即改变木材的化学结构,以增强纤维素部分的酶水解。
