Recent anthropogenic emissions of key atmospheric trace gases (e.g. CO2 and CH4) which absorb infra-red radiation may lead to an increase in mean surface temperatures and potential changes in climate. Although sources of each gas have been evaluated independently, little attention has focused on potential interactions between gases which could influence emission rates. In the current experiment...

A simple yet efficient method to remove organic ligands from supported nanocrystals is reported for activating uniform catalysts prepared by colloidal synthesis procedures. The method relies on a fast thermal treatment in which ligands are quickly removed in air, before sintering can cause changes in the size and shape of the supported nanocrystals. A short treatment at high temperatures is fou...

Ethylene is the most produced organic substance in world and a pillar chemical process industry. The production pathway energy intensive has corresponding high carbon footprint. This work explores, simulates, presents possibility of reforming fuel gas steam cracking furnace. Currently, methane (CH4) hydrogen (H2) from furnace outlet makes up source. If H2 by reformation current can cover demand...

This communication presents the successful design of a structured catalyst based on porous anodic alumina membranes for methane dry reforming. The catalyst with a strong Ni-NiAl2O4 interaction shows both excellent activity and stability.

CO-free hydrogen is produced by the reversible cyclic stepwise steam reforming of methane for use in fuel cells and other processes that are sensitive to CO poisoning. The process consists of two steps involving the decomposition of methane in a first step followed by steam gasification of the surface carbon in a second step. The ease of carbon removal in step II is strongly dependent on temper...

This Special Issue, entitled “Methane Reforming Processes”, of the MDPI journal Processes, embraces wide-ranging aspects interest in exploitation methane reforming reactions and related chemical species, from a point view that aligns with scope this open access [...]

The possibility of optimizing the composition and the structures of the nickel catalysts and the pretreatment and reaction conditions for carbon dioxide reforming with methane is investigated. The optimum catalyst and the pretreatment and reaction conditions are determined employing the orthogonal and uniform design methods. The optimum nickel catalyst gives promising catalytic performance in t...

This work establishes the primordial role played by support’s nature when aimed at constitution of Ni2P active phases for supported catalysts. Thus, carbon dioxide reforming methane was studied over three novel catalysts on Al2O3, CeO2 and SiO2-Al2O3 oxides. The catalytic performance, shown catalysts’ series, decreased according to sequence: Ni2P/Al2O3 > Ni2P/CeO2 Ni2P/SiO2-Al2O3. depleted C...

Continued warming of the Arctic Ocean in coming decades is projected to trigger the release of teragrams (1 Tg = 106 tons) of methane from thawing subsea permafrost on shallow continental shelves and dissociation of methane hydrate on upper continental slopes. On the shallow shelves (<100 m water depth), methane released from the seafloor may reach the atmosphere and potentially amplify global ...
