Date palm waste biomass is a readily accessible agricultural waste biomass that may be used to produce biogas. Because the complex structure of date palm waste biomass prevents the embedded holo-cellulosic sugars from biodegrading, pretreatment is required to increase methane (CH) yield. The present investigation aimed to comparatively determine the impact of alkali and ionic liquid pretreatment on the biochemical methane potential (BMP) of different types of date palm waste biomass. The findings revealed that ionic liquid pretreated Palm and Fruit bunch showed the highest BMP (321.67 mL CH/g-TS) and substrate conversion efficiency (68.01%), respectively, over other biomass samples. In alkali pretreatment, the highest BMP and substrate conversion efficiency were detected with Palm (309.76 mL CH/g-TS) and Spathe (62.09%). The high BMP and substrate conversion efficiency of date palm waste biomass may be harnessed for bioenergy production when this ionic liquid pretreatment technology is used.

碱与离子液体预处理方法对海枣废弃物生物质生化甲烷潜力的比较



枣椰树废弃物生物质是一种易于获取的农业废弃物生物质,可用于生产沼气。由于海枣废弃物生物质的复杂结构阻碍了嵌入的全纤维素糖的生物降解,因此需要进行预处理以增加甲烷(CH)产量。本研究旨在比较确定碱和离子液体预处理对不同类型海枣废弃物生物质生化甲烷势(BMP)的影响。结果表明,与其他生物质样品相比,离子液体预处理的棕榈和果串分别显示出最高的 BMP (321.67 mL CH/g-TS) 和底物转化效率 (68.01%)。在碱预处理中,Palm (309.76 mL CH/g-TS) 和 Spathe (62.09%) 检测到最高的 BMP 和底物转化效率。当使用这种离子液体预处理技术时,海枣废弃物生物质的高BMP和底物转化效率可以用于生物能源生产。
