10种林业生物质资源化学成分及液化应用分析

Analysis of Chemical Components and Liquefaction Using of Ten Types Forestry Biomass Materials

林业生物质资源的化学成分是其作为液化利用原料的主要指标之一。本研究以可液化利用的小径竹为对照,对比分析了山核桃、油茶和板栗的果壳和果蓬,香榧和银杏的果壳和果皮等10种林业生物质资源的主要化学成分。结果表明:与小径竹相比,油茶、银杏果壳和香榧果壳的化学成分含量与之较为相似,可以直接进行液化利用;山核桃和板栗果壳的综纤维素和酸不溶木质素含量较高,但是它们的抽提物含量也较高,在液化利用时需要适当提高液化环境;其他几种不适宜直接作为液化利用的原料。

The chemical components of forestry biomass materials is one of the main indicators as raw materials using liquefied. This paper comparatively analyzed the chemical content from husk and shell of hickory, sasanqua, Chinese chestnut, ginkgo and torreya grandis to bamboo. The results show that compared with bamboo, the chemical components from shell of sasanqua, ginkgo and torreya grandis is relatively similar, can directly be liquefied. Hickory shell and Chinese chestnut shell of holocellulose and acid-insoluble lignin content is higher, at the same time extractive content is also higher, so the condition of the reactions need improve when they are used for liquefaction. Other forestry biomass materials of chemical composition is not suitable as raw materials by liquefaction.
