摘要

木质素是一种生物聚合物，一旦从生物质中分离和去木素化，它就可以以多种方式使用。在本培训报告中，进行了椰子壳纤维的脱木质素，目的是回收分离的木质素。为了做到这一点，进行了不同的工艺(自水解，稀酸，有机溶剂和碱制浆处理)。然后通过傅里叶变换红外(FTIR)、1H和13C核磁共振(NMR)对得到的木质素进行表征，以检查木质素的存在和质量。分析表明，在两个实验中确实得到了木质素，尽管自水解处理的产率更高。但整体收率较低，需要对实验参数(时间、温度、比例)进行调整。

Effect of Different Prehydrolysis Processes on Lignin Extractability of Coconut Husk Fibres

Lignin is a biopolymer usable in many ways once it has been separated and delignified from biomass. In this training report, delignification of coconut husk fibres is performed, with the aim of recovering isolated lignin. In order to do so, different processes are carried out (autohydrolysis, dilute acid, organosolv and soda pulping treatments). The obtained lignin is characterised afterwards through Fourier transform infrared (FTIR), 1H and 13C nuclear magnetic resonance (NMR) in order to check lignin presence and quality. Analyses show that lignin is indeed obtained in both experiments, though the yield is greater for the treatment with autohydrolysis. However, the global yield is quite low, adjustments of experimental parameters (time, temperature, ratio) shall be carried out.
