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.
椰枣废弃物生物质是一种易于获得的农业废弃物生物质，可用于生产沼气。由于椰枣废弃物生物质的复杂结构阻止了嵌入式全纤维素糖的生物降解，因此需要预处理来提高甲烷 (CH) 的产量。本研究旨在比较碱法和离子液体预处理对不同类型椰枣废弃物生物质生物化学甲烷潜能 (BMP) 的影响。研究结果表明，与其他生物质样品相比，离子液体预处理的椰枣果和果穗表现出最高的 BMP（321.67 毫升 CH/g-TS）和底物转化效率（68.01%）。在碱预处理中，Palm 和 Spathe 表现出最高的 BMP 和底物转化效率（309.76 毫升 CH/g-TS 和 62.09%）。当使用这种离子液体预处理技术时，椰枣废弃物生物质的高 BMP 和底物转化效率可用于生物能源生产。
