“…In this context, hydrogen is often mentioned as an important energy carrier of the future (Ehret and Bonhoff 2015), and in order to that, one of the most promising alternatives to fossil fuels (Saxena et al 2009). Hydrogen is also frequently associated with its positive effect on global warming and greenhouse gas emissions, which are growing issues on technological as well as societal and political levels (Bulatov and Klemeš 2011). Unfortunately, as Duić (2015) states, the effect of climate change is still not strong enough a reason to facilitate the development of alternatives, because the user still has the benefit from using fossil fuels whereas the resulting damage is a global one.…”

Hydrogen is known as one of the most promising energy carriers of the future. Its production in a sustainable manner is therefore an important step towards a competitive alternative to fossil energy sources. Dark fermentation is such a sustainable pathway, as hydrogen is produced via biotechnological conversion of biomass. But, the resulting hydrogen-rich gas from fermentation still needs to be upgraded, which can be done via membrane technology. In this work, an innovative small-scale process was developed, membrane modules were assembled and tested, and the purification method was simulatively investigated. The laboratory tests with pure gases showed that the utilized commercially available H 2 -selective membranes have an ideal H 2 /CO 2 -selectivity of 3.3, at the respective process conditions. When applying gas mixtures, the H 2 /CO 2 -selectivity was reduced. To further investigate the purification method, an Aspen Plus Ò gas permeation simulation model was used. The single-stage model was evaluated and it reflected the results from field and laboratory tests well. Furthermore, three different multi-stage setups were developed, simulated, and analyzed. The utilization of H 2 -selective material in a two-stage process resulted in a specific energy demand of 0.400 kWh/Nm 3 H 2 , but achieved no sufficient hydrogen purity. Compared to that, the use of CO 2 -selective membranes demanded only 0.296 kWh/Nm 3 H 2 . The recycle to feed ratio, as well as the H 2 -puriy of 95.5 vol% in the product was also in favor of the CO 2 -selective membranes compared to the commercially available H 2 -selective material.

“…Coalbed methane is an unconventional natural gas resource endowed in coal seams, with CH 4 as its main component (Asif et al, 2022;Gao et al, 2023). As a clean energy source with high calorific value and abundant reserves, coalbed methane has an important position and great potential in the energy field (Butalov and Klemes, 2011;Zhou et al, 2016;Jia et al, 2019). However, the utilization rate of coalbed methane in China is still under 50% (Zhang et al, 2021).…”

Methane hydration is a safe, stable and environmentally friendly technology to bind and utilize excess coalbed methane gas. However, a limiting factor of the commercial application of coalbed methane hydration technology is the sluggish hydration reaction kinetics of methane hydrate formation, which needs to be improved. In this work, different micro-particle suspensions are prepared from an initial solution containing gellan gum and L-tryptophan, along with varying mass fractions of NiMnGa, Cu and carboxylated multi-walled carbon nanotubes, and their influence on the reaction kinetics in methane hydrate formation is examined. The results show that the formation of methane hydrate is enhanced by these micro-particles to varying degrees. Micro-particles show a synergistic solubilization effect with L-tryptophan and gellan gum at 6.2 MPa. The induction times of 1 wt.% NiMnGa system and 1 wt.% Cu system are the shortest. The 2 wt.% NiMnGa system has a pronounced impact on methane gas consumption, and the average gas consumption rates of the 0.1 wt.% Cu system and 1 wt.% NiMnGa system are faster. However, as the concentration of Cu micro-particles increases, both gas consumption and the average generation rate exhibits a linear decrease. This work offers valuable recommendations for choosing the experimental settings, micro-particle types and concentrations. We also lay the groundwork for the practical and sustainable application of coalbed methane storage and transportation technology employing the hydrate approach.
