使用较低成本的原料制造氢气,废弃有机物(WOs),例如,厨房垃圾生物油,是一个双赢的解决方案,因为它既能解决能源问题,又能减少环境污染。超声波在有机分解方面引起了相当大的兴趣;然而,单独应用超声波不是从WOs制氢的好选择,因为能耗和效率。为提高生物油超声空化裂解制氢性能,将光热材料引入制氢系统以形成局部热点。材料炭黑(CB),碳纳米管(CNT),和二氧化硅(SiO2)都对生物油的制氢表现出显着的增强作用,在这些材料中,CB表现出最显著的增强作用。当CB的剂量为5mg时,氢气的产生速率为180.1μmol·h-1,与没有CB的产生速率相比,显着提高了1.7倍。在光和超声波的存在下,与仅存在光而没有超声的情况相比,氢气产生速率可以增加66.7倍。
The creation of
hydrogen using the lower-cost feedstock, waste organics (WOs), e.g. kitchen waste bio-oil, is a win-win solution, because it can both solve energy problems and reduce environmental pollution. Ultrasound has received considerable interest in organic decomposition; however, the application of ultrasound alone is not a good choice for the
hydrogen production from WOs, because of the energy consumption and efficiency. To boost the
hydrogen production based on ultrasonic cavitation cracking of bio-oil, photothermal materials are introduced into the
hydrogen production system to form localized hot spots. Materials carbon black (CB), carbon nanotubes (CNT), and silicon dioxide (SiO2) all exhibit significant enhancing effects on the hydrogen production from bio-oil, and the CB exhibits the most significant strengthening effect among these materials. When the dosage of CB is 5 mg,
hydrogen production rate is 180.1 μmol · h-1, representing a notable 1.7-fold increase compared to the production rate without CB. In the presence of light and ultrasound, the hydrogen production rate can be increased by 66.7-fold compared to the situation where only light is present without ultrasound.
