“…Furthermore, ashes of the raw lignite coal and raw sawdust biomass were prepared as followed. As to lignite, its ash was prepared according to Chinese National Standard (GB/T 212-2001) and heated in the muffle furnace from the ambient to 815°C withhold time for one hour, while for sawdust biomass, its ash was conducted by ASTM E870-82 as suggested by Wang et al (2011) and its final ashing temperature was only 600°C in avoidance of the inherent mineral vaporization. And the chemical composition of ashes of both samples is listed in Table 1.…”

This study aims at investigating the interaction and kinetics behavior of the co-gasification of digestate and lignite. The co-pyrolysis performances of digestate and lignite blended by dry process were better than that blended by wet process, while the wet-blending process could improve the performance in co-gasification stage because of the larger pore diameter and pore volume. When anaerobic digestion (AD) time was 40 days, the synergistic interaction between digestate and lignite were the most remarkable based on the results of thermogravimetric analysis (TG) and the experiments in the lab-scale downdraft fixed bed gasifier. Kinetics study showed that the increase of AD time and the addition of digestate in lignite decreased the activation energy of the co-gasification reaction.

“…Crop stalk is a kind of biomass resource existing in China, the annual crop stalks can reach about 0.5 billion tons, corn stovers accounted for 33％ in 2016 [20]. The common domestic use methods are composting, open burning or biogas production and forming fuels [21][22][23]. Since the corn stover contains a large amount of cellulose, hemicellulose and lignin, the pretreatment of the corn stover for dark fermentation biological hydrogen production not only reduces the cost of biological hydrogen production, but also expands the source of biological hydrogen production raw materials, which is a promising way of hydrogen production.…”

2020) Statistical optimization of simultaneous saccharification fermentative hydrogen production from corn stover, Bioengineered, 11:1, 428-438, ABSTRACT Corn stovers are rich in carbohydrates and can be used by anaerobic bacteria to produce hydrogen by fermentation. In the present study, using hydrogen production as the main experimental index, the effect of different influential factors on hydrogen production from corn stover saccharification and fermentation was studied, using the response surface method BBD model. The significance of interactions between different influential factors on hydrogen production by simultaneous saccharification and fermentation of corn stover material were investigated and optimized. Results showed that there were several factors affecting simultaneous saccharification fermentative hydrogen production from corn stover, including substrate concentration, inoculation amount, pH value and enzyme concentration. In linear terms, substrate concentration had the greatest influence on hydrogen production by anaerobic simultaneous saccharification and fermentation. In terms of multi-factor interactions, the interaction between pH and enzyme concentration was the most significant. The optimal hydrogen production conditions established from the BBD model were as follows: substrate concentration of 25 mg/mL, inoculation amount proportion of 32.62%, initial pH value of 6.50 and enzyme concentration of 172.08 mg/g, resulting in the maximum hydrogen production of 55.29 mL/g TS. The actual maximum hydrogen production reached 56.66 mL/g TS, with these experimental results consistent with the predicted value established from equation fitting. This study provides a reference for hydrogen production by anaerobic synchronous saccharification fermentation using corn stover as substrate and lays a foundation and provides technical support for the industrialization of biological hydrogen production using corn stover as substrate.
