微波辅助酸水解预处理（MAHP）方法已被开发用于提高草药提取过程残留物（HPR）前的沼气产量。与传统的酸水解预处理（AHP）和微波辅助水水解预处理（MWHP）相比，微波辐射和酸相结合的HPR预处理可以从HPR中释放出更多的可溶性物质，并使HPR更容易进行厌氧生物消化。当H2SO4浓度为1.2%（w/w）时，MAHP水解HPR 30分钟，19天后最大累计沼气产量达到1272 mL。目前的工作表明，MAHP 是改善木质纤维素废物生物转化为可再生能源的一种有前途的方法。
A microwave-assisted acid hydrolysis pretreatment (MAHP) method has been developed for the enhancement of biogas production front herbal-extraction process residue (HPR). HPR pretreated by combining microwave irradiation and acid resulted in releasing more soluble substances from HPR and making more accessibility of HPR for anaerobic biodigestion in comparison to traditional acid hydrolysis pretreatment (AHP) and microwave-assisted water hydrolysis pretreatment (MWHP). The maximum cumulative biogas production reached 1272 mL after 19 days when the HPR was hydrolyzed by MAHP for 30 min at a H2SO4 concentration of 1.2% (w/w). The present work demonstrated that MAHP was a promising way for improving bioconversion of lignocellulosic wastes to renewable energy.
