Mechanical refining of lignocellulosic biomass has emerged as a promising technology for the improvement of enzymatic hydrolysis yields. Further research is necessary to understand the effects of mechanical refining at different conditions to allow for further optimization of the process. In this research, the impact of refining intensity (specific edge load; kWh/m) is investigated by the use of multiple refining passes to reach equivalent total specific refining energy (SRE) using a 12-in. disk refiner. In addition, the effect of adjusting gap-width vs adjusting consistency to increase refining energy is explored. Results show that enzymatic carbohydrate conversion is a function of SRE, independent of refining intensity. At lower enzyme loadings, gap-width adjustments were observed to be most effective at improving enzymatic digestibility. At higher enzyme loadings carbohydrate conversions leveled-off slightly as SRE increased, implying that there may be an economically optimum degree of refining.

机械精炼能量对木质纤维素生物质酶消化率的影响

机械精制木质纤维素生物质已成为提高酶水解产量的有前途的技术。有必要进行进一步的研究以了解在不同条件下机械精炼的效果，以便进一步优化工艺。在这项研究中，通过使用12英寸的多次精炼道次以达到等效的总总精炼能量（SRE），研究了精炼强度（比边缘负荷； kWh / m）的影响。磁盘优化器。此外，还探讨了调节间隙宽度与调节稠度以提高精炼能量的效果。结果表明，酶碳水化合物的转化是SRE的功能，与提纯强度无关。在较低的酶负载下，观察到间隙宽度的调节在改善酶消化率方面最有效。
