Effect of different gas releasing methods on anaerobic fermentative hydrogen production in batch cultures

Sheng CHANG, Jianzheng LI, Feng LIU, Ze YU

《环境科学与工程前沿（英文）》 2012年 第6卷 第6期   页码 901-906 doi: 10.1007/s11783-012-0403-1

摘要： Decreasing hydrogen partial pressure can not only increase the activity of the hydrogen enzyme but also decrease the products inhibition, so it is an appropriate method to enhance the fermentative hydrogen production from anaerobic mixed culture. The effect of biogas release method on anaerobic fermentative hydrogen production in batch culture system was compared, i.e., Owen method with intermediately release, continuous releasing method, and continuous releasing+ CO absorbing. The experimental results showed that, at 35°C, initial pH 7.0 and glucose concentration of 10 g·L , the hydrogen production was only 28 mL when releasing gas by Owen method, while it increased two times when releasing the biogas continuously. The cumulative hydrogen production could reach 155 mL when carbon dioxide in the gas stream was continuously absorbed by 1 mol·L NaOH. The results showed that acetate was dominated, accounting for 43% in the dissolved fermentation products in Owen method, whereas the butyrate predominated and reached 47%–53% of the total liquid end products when releasing gas continuously. It is concluded that the homoacetogenesis could be suppressed when absorbing CO in the gas phase in fermentative hydrogen production system.

Bo WANG, Wei WAN, Jianlong WANG,

《环境科学与工程前沿（英文）》 2009年 第3卷 第4期   页码 380-386 doi: 10.1007/s11783-009-0142-0

摘要： The effects of nitrate on fermentative hydrogen production and soluble metabolites from mixed cultures were investigated by varying nitrate concentrations from 0 to 10g N/L at 35°C with an initial pH of 7.0. The results showed that the substrate degradation rate, hydrogen production potential, hydrogen yield, and average hydrogen production rate initially increased with increasing nitrate concentrations from 0 to 0.1g N/L, while they decreased with increasing nitrate concentrations from 0.1 to 10g N/L. The maximum hydrogen production potential of 305.0mL, maximum hydrogen yield of 313.1mL/g glucose, and maximum average hydrogen production rate of 13.3mL/h were obtained at a nitrate concentration of 0.1g N/L. The soluble metabolites produced by the mixed cultures contained only ethanol and acetic acid (HAc) without propionic acid (HPr) and butyric acid (HBu). This study used the Modified Logistic model to describe the progress of cumulative hydrogen production in batch tests. A concise model was proposed to describe the effects of nitrate concentration on average hydrogen production rate.

Gefu ZHU, Chaoxiang LIU, Jianzheng LI, Nanqi REN, Lin LIU, Xu HUANG

《环境科学与工程前沿（英文）》 2013年 第7卷 第1期   页码 143-150 doi: 10.1007/s11783-012-0456-1

摘要： A low pH, ethanol-type fermentation process was evaluated for wastewater treatment and bio-hydrogen production from acidic beet sugar factory wastewater in a continuous stirred tank reactor (CSTR) with an effective volume of 9.6 L by anaerobic mixed cultures in this present study. After inoculating with aerobic activated sludge and operating at organic loading rate (OLR) of 12 kgCOD?m ·d , HRT of 8h, and temperature of 35°C for 28 days, the CSTR achieved stable ethanol-type fermentation. When OLR was further increased to 18 kgCOD?m ·d on the 53rd day, ethanol-type fermentation dominant microflora was enhanced. The liquid fermentation products, including volatile fatty acids (VFAs) and ethanol, stabilized at 1493 mg·L in the bioreactor. Effluent pH, oxidation-reduction potential (ORP), and alkalinity ranged at 4.1–4.5, -250–(-290) mV, and 230–260 mgCaCO ?L . The specific hydrogen production rate of anaerobic activated sludge was 0.1 L?gMLVSS ·d and the COD removal efficiency was 45%. The experimental results showed that the CSTR system had good operation stability and microbial activity, which led to high substrate conversion rate and hydrogen production ability.

Continuous biohydrogen production from diluted molasses in an anaerobic contact reactor

Sheng CHANG, Jianzheng LI, Feng LIU

《环境科学与工程前沿（英文）》 2011年 第5卷 第1期   页码 140-148 doi: 10.1007/s11783-010-0258-2

摘要： An anaerobic contact reactor (ACR) system comprising a continuous flow stirred tank reactor (CSTR) with settler to decouple the hydraulic retention time (HRT) from solids retention time (SRT) was developed for fermentative hydrogen production from diluted molasses by mixed microbial cultures. The ACR was operated at various volumetric loading rates (VLRs) of 20–44 kgCOD·m ·d with constant HRT of 6 h under mesophilic conditions of 35°C. The SRT was maintained at about 46–50 h in the system. At the initial VLR of 20 kgCOD·m ·d , the hydrogen production rate dropped from 22.6 to 1.58 L·d as the hydrogen was consumed by the hydrogentrophic methanogen. After increasing the VLR to 28 kgCOD·m ·d and discharging the sludge for 6 consecutive times, the hydrogentrophic methanogens were eliminated, and the hydrogen content reached 36.4%. As the VLR was increased to 44 kgCOD·m ·d , the hydrogen production rate and hydrogen yield increased to 42.1 L·d and 1.40 mol H ·molglucose-consumed , respectively. The results showed that a stable ethanol-type fermentation that favored hydrogen production in the reactor was thus established with the sludge loading rate (SLR) of 2.0–2.5 kgCOD·kgMLVSS ·d . It was found that the ethanol increased more than other liquid fermentation products, and the ethanol/acetic acid (mol/mol) ratio increased from 1.27 to 2.45 when the VLR increased from 28 to 44 kgCOD·m ·d , whereas the hydrogen composition decreased from 40.4% to 36.4%. The results suggested that the anaerobic contact reactor was a promising bioprocess for fermentative hydrogen production.

Production of hydrogen from fossil fuel: A review

《能源前沿（英文）》 2023年 第17卷 第5期   页码 585-610 doi: 10.1007/s11708-023-0886-4

摘要： Production of hydrogen, one of the most promising alternative clean fuels, through catalytic conversion from fossil fuel is the most technically and economically feasible technology. Catalytic conversion of natural gas into hydrogen and carbon is thermodynamically favorable under atmospheric conditions. However, using noble metals as a catalyst is costly for hydrogen production, thus mandating non-noble metal-based catalysts such as Ni, Co, and Cu-based alloys. This paper reviews the various hydrogen production methods from fossil fuels through pyrolysis, partial oxidation, autothermal, and steam reforming, emphasizing the catalytic production of hydrogen via steam reforming of methane. The multicomponent catalysts composed of several non-noble materials have been summarized. Of the Ni, Co, and Cu-based catalysts investigated in the literature, Ni/Al2O3 catalyst is the most economical and performs best because it suppresses the coke formation on the catalyst. To avoid carbon emission, this method of hydrogen production from methane should be integrated with carbon capture, utilization, and storage (CCUS). Carbon capture can be accomplished by absorption, adsorption, and membrane separation processes. The remaining challenges, prospects, and future research and development directions are described.

A mini-review of ferrites-based photocatalyst on application of hydrogen production

《能源前沿（英文）》 2021年 第15卷 第3期   页码 621-630 doi: 10.1007/s11708-021-0761-0

摘要： Photocatalytic water splitting for hydrogen production is a promising strategy to produce renewable energy and decrease production cost. Spinel-ferrites are potential photocatalysts in photocatalytic reaction system due to their room temperature magnetization, the high thermal and chemical stability, narrow bandgap with broader visible light absorption, and proper conduction band energy level with strong oxidation activity for water or organic compounds. However, the fast recombination of the photoexcited electrons and holes is a critical drawback of ferrites. Therefore, the features of crystallinity, particle size, specific surface area, morphology, and band energy structure have been summarized and investigated to solve this issue. Moreover, composites construction with ferrites and the popular support of TiO2 or g-C3N4 are also summarized to illustrate the advanced improvement in photocatalytic hydrogen production. It has been shown that ferrites could induce the formation of metal ions impurity energy levels in TiO2, and the strong oxidation activity of ferrites could accelerate the oxidation reaction kinetics in both TiO2/ferrites and g-C3N4/ferrites systems. Furthermore, two representative reports of CaFe2O4/MgFe2O4 composite and ZnFe2O4/CdS composite are used to show the efficient heterojunction in a ferrite/ferrite composite and the ability of resistance to photo-corrosion, respectively.

Efficient flower-like ZnSe/CuZnS photocatalyst for hydrogen production application

《化学科学与工程前沿（英文）》 2023年 第17卷 第9期   页码 1301-1310 doi: 10.1007/s11705-022-2295-3

摘要： Photocatalytic hydrogen production utilizing abundant solar energy to produce high-calorie, clean, and pollution-free hydrogen is an important approach to solving environmental and resource problems. In this work, a high-efficiency flower-like ZnSe/Cu0.08Zn0.92S photocatalyst was constructed through element doping and the formation of a Z-scheme heterojunction. The synergistic effect of Cu doping and the built-in electric field in the heterojunction enhanced light absorption and utilization by the ZnSe/Cu0.08Zn0.92S microflowers, accelerated the separation and transfer of photogenerated electrons and effectively inhibited electron–hole recombination. Thus the photocatalytic hydrogen production ability of the ZnSe/Cu0.08Zn0.92S microflowers was increased significantly. The highly stable ZnSe/Cu0.08Zn0.92S microflowers could provide excellent catalysis of photocatalytic hydrogen production.

《能源前沿（英文）》 2021年 第15卷 第3期   页码 596-599 doi: 10.1007/s11708-021-0745-0

摘要： Photoelectrochemical (PEC) water splitting is regarded as a promising way for solar hydrogen production, while the fast development of photovoltaic-electrolysis (PV-EC) has pushed PEC research into an embarrassed situation. In this paper, a comparison of PEC and PV-EC in terms of efficiency, cost, and stability is conducted and briefly discussed. It is suggested that the PEC should target on high solar-to-hydrogen efficiency based on cheap semiconductors in order to maintain its role in the technological race of sustainable hydrogen production.
