摘要: <正>利用嗜黑液菌对木质素进行厌氧降解处理,研究在厌氧降解过程中,木质素的元素组成、分子量、结构基团的变化及其红外光谱和氢谱。结果表明,在厌氧降解过程中,分子量大于4950的木质素将发生碎片化反应,尤其是木质素结构中的香豆满和松脂醇结构,以及β-O-4和β-β结构都因为发生断裂而消失,同时进一步发生脱甲氧基作用和脱羟基作用,生成了可溶性小分子化合物。

Abstract: The drying equipment of two-stage compressing high temperature heat pump was developed. This heat pump drying equipment can switch between the first stage compressor and the second stage compressor. Components and the working principle of two-stage compressing high temperature heat pump equipment were introduced. Drying experiment was conducted with Pinus massoniana. Results showed that this equipment had a great energy saving performance, the average energy recycling rate could achieve beyond 28%.
