This research work aimed about the enhanced bio-hydrogen production from marine macro algal biomass (Ulva reticulate) through surfactant induced microwave disintegration (SIMD). Microwave disintegration (MD) was performed by varying the power from 90 to 630 W and time from 0 to 40 min. The maximum chemical oxygen demand (COD) solubilisation of 27.9% was achieved for MD at the optimal power (40%). A surfactant, ammonium dodecyl sulphate (ADS) is introduced in optimal power of MD which enhanced the solubilisation to 34.2% at 0.0035 g ADS/g TS dosage. The combined SIMD pretreatment significantly reduce the treatment time and increases the COD solubilisation when compared to MD. Maximum hydrogen yield of 54.9 mL H /g COD was observed for SIMD than other samples. In energy analysis, it was identified that SIMD was energy efficient process compared to others since SIMD achieved energy ratio of 1.04 which is higher than MD (0.38).
本研究旨在通过表面活性剂诱导的微波解体(SIMD)提高海洋大型藻类生物质(网纹藻)的生物制氢效率。通过改变微波功率(90 至 630 W)和时间(0 至 40 分钟)进行微波解体(MD)实验。在最佳功率(40%)下,MD 的最大化学需氧量(COD)溶解率达到 27.9%。在最佳 MD 功率下引入表面活性剂十二烷基硫酸铵(ADS),COD 溶解率提高至 0.0035 g ADS/g TS 剂量下的 34.2%。与 MD 相比,组合的 SIMD 预处理可显著缩短处理时间并提高 COD 溶解率。与其他样品相比,SIMD 的最大氢气产率为 54.9 mL H 2 /g COD。在能量分析中,与其他方法相比,SIMD 是一种更节能的工艺,因为 SIMD 实现的能量比为 1.04,高于 MD(0.38)。
