“…Further, microorganisms can ferment the sugars resulting from hydrolysis to obtain biofuels. Depending on the microorganism, ethanol [73] or biohydrogen [74] can be produced ( Figure 6). Moreover, the microwave-assisted chemical reaction significantly reduces reaction time.…”

Fossil fuels have been a major contributor to greenhouse gases, the amounts of which could be reduced if biofuels such as bioethanol and biodiesel were used for transportation. One of the most promising biofuels is ethyl alcohol. In 2015, the world production of ethanol was 25.6 billion gallons and the USA, Brazil, China, the European Union, and 28 other countries have set targets for blending ethanol with gasoline. The two major bio-source materials used for ethanol production are corn and sugarcane. For 1st generation biofuels, sugarcane and corn feedstocks are not able to fulfill the current demand for alcohol. Non-edible lignocellulosic biomass is an alternative bio-source for creating 2nd generation biofuels and algae biomass for 3rd and 4th generation biofuels. This review discusses the significance of biomass for the different generations of biofuels, and biochemical and thermochemical processes, and the significance of biorefinery products.

“…The chemical composition and low cost of SBP makes this substrate attractive for many branches of the chemical industry for its biotechnological [3] and chemical [4] properties. Sugar beet pulp is a type of lignocellulosic biomass and consists mostly of carbohydrates (cellulose 22-30%, hemicellulose 24-32%, 2 of 17 lignin 1-2%) and polymeric saccharides (pectin 38-62% of the dry matter) [3,5]. Enzymatic, chemical, or thermal hydrolysis of these polymeric substances is a crucial step for valorizing SPB.…”

This study investigates a simultaneous processing of sugar beet pulp (SBP) for furfural, hydrogen and methane production using various pretreatment methods. In the experiments, sugar beet pulp was first subjected to thermal and thermochemical pretreatment at 140 °C. Then hydrolysates from these operations were investigated for their potential for methane and hydrogen production in batch tests. The experiments showed that thermal pretreatment of SBP resulted in the highest biogas and methane yields of 945 dm3/kg volatile solids (VS) and 374 dm3 CH4/kg VS, respectively, and a moderate hydrogen production of 113 dm3 H2/kg VS, which corresponded to a calculated energy production of 142 kWh/t; however, only low amount of furfural was obtained (1.63 g/L). Conversely, the highest furfural yield of 12 g/L was achieved via thermochemical pretreatment of SBP; however, biogas production from hydrolysate was much lower (215 dm3/kg VS) and contained only 67 dm3/kg VS of hydrogen. Meanwhile, in the experiment with lower amounts of sulfuric acid (2%) used for pretreatment, a moderate furfural production of 4 g/L was achieved with as high as 220 dm3/kg VS of hydrogen and the corresponding energy yield of 75 kWh/t.

“…The integrated fermentative biohydrogen generation approach has been studied in different stages of the photo-fermentative and dark fermentative processes (Ghosh et al, 2018). Some workers have coupled dark fermentation with biocatalysed electrolytic processes for hydrogen production from process residues (Moreno et al, 2015;Dhar et al, 2015;Marone et al, 2017) whereas others have investigated the performance of combined fermentation and heterogeneous catalysis (for example, Wimonsong et al (2014) and Güell et al (2015)). Results from studies where sequential dark fermentation and photo-fermentation of biomass have been employed demonstrate the merits of this type of combined operational procedure in terms of the enhanced biohydrogen kinetics.…”

A review of research trends in the enhancement of biomass-to-hydrogen conversion

et al. 2018

Different types of biomass are being examined for their optimum hydrogen production potentials and actual hydrogen yields in different experimental setups and through different chemical synthetic routes. In this review, the observations emanating from research findings on the assessment of hydrogen synthesis kinetics during fermentation and gasification of different types of biomass substrates have been concisely surveyed from selected publications. This review revisits the recent progress reported in biomass-based hydrogen synthesis in the 2 associated disciplines of microbial cell immobilization, bioreactor design and analysis, ultrasound-assisted, microwave-assisted and ionic liquid-assisted biomass pretreatments, development of new microbial strains, integrated production schemes, applications of nanocatalysis, subcritical and supercritical water processing, use of algae-based substrates and lastly inhibitor detoxification. The main observations from this review are that cell immobilization assists in optimizing the biomass fermentation performance by enhancing bead size, providing for adequate cell loading and improving mass transfer; there are novel and more potent bacterial and fungal strains which improve the fermentation process and impact on hydrogen yields positively; application of microwave irradiation and sonication and the use of ionic liquids in biomass pretreatment bring about enhanced delignification, and that supercritical water biomass processing and dosing with metal-based nanoparticles also assist in enhancing the kinetics of hydrogen synthesis. The research areas discussed in this work and their respective impacts on hydrogen synthesis from biomass are arguably standalone. Thence, further work is still required to explore the possibilities and techno-economic implications of combining these areas for developing robust and integrated biomass-to-hydrogen synthetic schemes.
