Pre-treatment of lignocellulosic biomass is an inevitable step toward value-added green chemicals. There are various modes of pre-treatment method that exist with their own pros and cons. The present study focused on the utilization of the shell of groundnut as lignocellulosic biomass material. The groundnut shell has no use after the collection of nuts from it. Preliminary characterization of groundnut shell was also conducted which showed it has 48.2% cellulose and hemicellulose; the lignin content was found to be 48.67%. The ash content of the biomass was around 3.13%. The lignin content of the biomass was considered as the target response for the pre-treatment process and butanol was used as an organic solvent for the pre-treatment process. The experimental study developed a quadratic model for the entire process with respect to the change in the lignin profile within the design criteria. The study also conducted raw and pre-treated biomass characterization using Fourier transform infrared spectroscopy. The study revealed that the maximum amount of lignin removed was 48.67% lignin.

花生壳的有机溶剂预处理及其效果

木质纤维素生物质的预处理是迈向增值绿色化学品的必然步骤。预处理方法有多种模式,各有其优缺点。本研究的重点是利用花生壳作为木质纤维素生物质材料。花生壳从螺母壳中收集后就没有用了。还对花生壳进行了初步表征,结果表明花生壳具有48.2%的纤维素和半纤维素。木质素含量为48.67%。生物质的灰分含量约为3.13%。生物质中木质素的含量被认为是预处理过程的目标响应,而丁醇被用作预处理过程的有机溶剂。实验研究针对设计标准内木质素分布的变化,为整个过程开发了一个二次模型。该研究还使用傅里叶变换红外光谱法对原始和预处理的生物质进行了表征。研究表明,木质素的最大去除量为48.67%。
