Hydrogen production by methane decomposition: A review
TL;DR: In this paper, a review of the development of metal or carbonaceous catalysts for enhanced methane conversion and on the improvement of long-term catalyst stability is presented, where the roles played by various parameters, such as temperature and flow rate, on the rate of hydrogen production and the characteristics of the carbon produced.

Low to near-zero CO2 production of hydrogen from fossil fuels: Status and perspectives
TL;DR: In this paper, the main technological approaches to low to near-zero CO2 production of hydrogen from fossil fuels can be classified into three main groups: coupling hydrogen plants with CO2 capture and storage systems, dissociation of hydrocarbons to hydrogen and carbon, and integrating hydrogen production processes with non-carbon energy sources such as nuclear and solar energy.
Journal ArticleDOI
Decomposition of hydrocarbons to hydrogen and carbon
TL;DR: In this paper, a review of catalytic decomposition of hydrocarbons for the CO2-free generation of hydrogen for fuel cell applications through a single-step cracking (decomposition, decarbonization, dehydrogenation, pyrolysis, splitting, or dissociation) is presented.
Journal ArticleDOI
Microwave-assisted catalytic decomposition of methane over activated carbon for CO2-free hydrogen production
TL;DR: In this article, the authors combine microwave heating with the use of low-cost granular activated carbon as a catalyst for the production of CO 2 -free hydrogen by methane decomposition in a fixed bed quartz-tube flow reactor.
Journal ArticleDOI
Production and characterization of Lemna minor bio-char and its catalytic application for biogas reforming
TL;DR: In this article, the yield of bio-char was determined as a function of L. minor pyrolysis temperature and sweep gas flow rate, and the changes in the reaction conditions (temperature and sweepgas flow rate) did not alter markedly the textural characteristics and BET surface area of the biochar produced.

Hydrogen via methane decomposition: an application for decarbonization of fossil fuels
TL;DR: In this paper, a single-step decomposition of methane and other hydrocarbons over carbon-based catalysts in an air/water free environment is discussed, where clean carbon is produced as a valuable byproduct of the process.
Journal ArticleDOI
Catalysis of methane decomposition over elemental carbon
TL;DR: In this article, the authors found that the catalytic activity of activated carbons is mostly determined by their origin, structure and surface area of the carbons, and they also found that activation activity of carbons depends on their properties.

Hydrogen production via the direct cracking of methane over silica-supported nickel catalysts
Tiejun Zhang,Michael D. Amiridis +1 more
TL;DR: In this article, the authors investigated the catalytic cracking of methane as an alternative route for the production of hydrogen from natural gas, and found that nickel supported on silica was active for this reaction producing stoichiometric amounts of hydrogen and carbon.

Hydrogen production via the direct cracking of methane over Ni/SiO2: catalyst deactivation and regeneration
TL;DR: In this paper, the authors showed that a 15.5% Ni/SiO 2 catalyst can be fully regenerated at 923 K with steam for up to 10 successive cracking/regeneration cycles without any significant loss of catalytic activity.
