Pretreatment plays an important role in enhanced methane production from lignocellulose material. In this study, four different types of heating processes such as hot air oven, autoclave, liquid hot water bath, and microwave oven were used for comparison. The study was carried out in a biochemical methane potential assay to evaluate the different thermal heating process for enhanced methane production. Methane yield was increased in varied proportions with reduced digestion time for different heating processes of thermal pretreatment with low heating temperature at high residence time. Hot air oven pretreatment (17.92%) showed a high yield of methane production followed by autoclave (13.44%), microwave oven (9.54%), and hot water bath (7.54%) than control samples. In addition, the effect of pretreatment on biodegradability was assessed with three different kinetic models. Modified Gompertz model presents similar experimental data with a high degree of best fit when compared with the other two models.

筛选不同的加热工艺以提高木质纤维素废料的甲烷产量

预处理在提高木质纤维素材料的甲烷产量中起着重要作用。在这项研究中,使用了四种不同类型的加热过程,例如热风烤箱,高压釜,液态热水浴和微波炉进行比较。该研究是在生物化学甲烷潜力测定中进行的,以评估不同的加热过程以提高甲烷的产生。在高停留时间下以较低的加热温度进行热处理的不同加热过程,甲烷的收率随着消化时间的减少而以不同的比例增加。与对照样品相比,热风烤箱预处理(17.92%)显示出高产甲烷量,其次是高压釜(13.44%),微波炉(9.54%)和热水浴(7.54%)。此外,用三种不同的动力学模型评估了预处理对生物降解性的影响。与其他两个模型相比,改进的Gompertz模型可提供相似的实验数据,并且具有最佳的拟合度。
