The aim of this study was to investigate the effect of storing methods of woodchips from two species, pine ( L.) and alder ( Mill.), on the basic chemical composition and sugar yield in liquid biofuel production. Two methods of storing woody biomass were used in the study-an open pile and a cover pile. The wood was felled at the end of November and was stored as industrial chips for eight months from December onward. After this time, material was collected for chemical composition analyses and enzymatic hydrolysis. The results of the chemical composition analysis of the wood for both studied species showed the influence of the type of storage on the composition of the individual structural components of the wood. Based on the results of the enzymatic hydrolysis of the woody biomass, it can be seen that, irrespective of the hydrolysed material (wood, cellulose, holocellulose), the material from the biomass stored in the open pile gave higher results. The hydrolysis efficiency also increased with time, independent of the type of material that was hydrolysed. The highest sugar yield from the enzymatic hydrolysis of wood was obtained for alder wood stored in an open pile. The highest sugar yield from the enzymatic hydrolysis of cellulose was obtained for cellulose extracted from alder wood-as well-that had been stored in an open pile.
本研究的目的是调查两种木材（松树和桤木）的木片储存方法对液体生物燃料生产中基本化学成分和糖产量的影响。本研究采用了两种储存木质生物质的方法——露天堆放和覆盖堆放。木材于11月底砍伐，并从12月起作为工业木片储存八个月。在此之后，收集材料进行化学成分分析和酶水解。对两种研究树种木材的化学成分分析结果表明，储存方式对木材各结构成分的组成有影响。基于木质生物质酶水解的结果可以看出，无论水解材料（木材、纤维素、全纤维素）如何，露天堆放储存的生物质材料都能得到更高的结果。水解效率也随时间增加，与水解材料的类型无关。露天堆放储存的桤木木材酶水解得到的糖产量最高。从露天堆放储存的桤木木材中提取的纤维素酶水解得到的糖产量也最高。
