Abstract:

The possibility of converting methane into hydrogen using a high-frequency induction plasma torch at the atmospheric pressure has been experimentally studied. The dependencies of the degree of methane conversion and the rate of hydrogen production were studied depending on the process conditions. It has been demonstrated that the degree of the methane-to-hydrogen conversion can reach values close to 100%. Keywords: methane plasmolysis, HF plasma torch, hydrogen.

Methane reforming is an interesting resource for obtaining hydrogen. DBD plasma-catalysis allows a direct use of electricity for methane reforming reactions, such as direct methane reforming (MR), dry methane reforming (DMR) and steam methane reforming (SMR).

Economically and ecologically, the thermal decomposition of methane is a promising process for large scale hydrogen production. In this experimental study, the non-catalytic decomposition of methane in the presence of small amounts of carbon dioxide was analyzed. At large scales, natural gas or biomethane are possible feedstocks for the thermal decomposition and can obtain up to 5% carbon dioxide. Gas recycling can increase the amount of secondary components even further. Experiments were conducted in a packed flow reactor at temperatures from 1250 to 1350 K.

Abstract:

This paper used annua as material to do a biogas fermentation experiment. The result suggests that biogas-fermentation by pretreated annua is a preferable approach compared with methane production followed by hydrogen production, only methane production, or only hydrogen production, due to its decreasing overall fermentation time, and increasing material utilization efficiency and energy conversion efficiency. It shows that the TS and VS utilization ratio of first hydrogen production then methane production is higher than that of first methane production then hydrogen production.

Abstract:

Hydrogen production from water splitting remains difficult due to the low equilibrium constant (e.g., Kp ≈ 2 × 10−8 at 900 °C). The coupling of methane combustion with water splitting in an oxygen transport membrane reactor can shift the water splitting equilibrium toward dissociation by instantaneously removing O2 from the product, enabling the continuous process of water splitting and continuous generation of hydrogen, and the heat required for water splitting can be largely compensated for by methane combustion. In this work, a CFD simulation model for the coupled membrane reactor was devel

For future sustainable development, choosing direct conversion of natural gas must consider circularity of chemical products and supply chains.

Abstract:

Methane pyrolysis offers a promising route for large-scale H2 production with carbon sequestration from natural gas. Earlier works have focused on gas-phase pyrolysis. However, the removal of the deposited carbon from the reactor without burning, the fouling of heat transfer surfaces and reactor blockages have limited commercialization of the technology. Liquid-phase pyrolysis, in which the gas is decomposed in molten metal or molten salt, may facilitate easier carbon separation and heat transfer, but often results in significant amounts of the liquid media species being trapped in the carbon.

Abstract:

Abstract The study explores the use of thermo-catalytic decomposition (TCD) of methane to produce hydrogen (H2) and solid carbon. The research focuses on the performance of a proprietary molten metal catalyst in a TCD reactor, evaluating methane conversion efficiency and carbon quality under various operating conditions, including flow rates, pressure, and temperature. The results demonstrate that increasing the temperature from 920°C to 1030°C enhances methane conversion efficiency from 61% to 94%. Catalyst loss was minimal at 0.03%/day, primarily due to manual solid carbon removal. The study

Abstract:

In the global search for the right alternative energy sources for a more sustainable future, hydrogen production has stood out as a strong contender. Hydrogen gas (H2) is well-known as one of the cleanest and most sustainable energy sources, one that mainly yields only water vapor as a byproduct. Additionally, H2 generates triple the amount of energy compared to hydrocarbon fuels. H2 can be synthesized from several technologies, but currently only 1% of H2 production is generated from biomass. Biological H2 production generated from anaerobic digestion is a fraction of the 1%.
