Valorizing the carbon byproduct of methane pyrolysis in batteries [PDF]
arXiv, 2022 While low-cost natural gas remains abundant, the energy content of this fuel can be utilized without greenhouse gas emissions through the production of molecular hydrogen and solid carbon via methane pyrolysis. In the absence of a carbon tax, methane pyrolysis is not economically competitive with current hydrogen production methods unless the carbon ...

A pyrolysis mechanism for ammonia [PDF]
International Journal of Chemical Kinetics, 1990 AbstractThe mechanism of NH3pyrolysis was investigated over a wide range of conditions behind reflected shock waves. Quantitative time‐history measurements of the species NH and NH2were made using narrow‐linewidth laser absorption. These records were used to establish an improved model mechanism for ammonia pyrolysis.

Dimethylsilanone generation from pyrolysis of polysiloxanes filled with nanosized silica and ceria/silica [PDF]
ChemPlusChem 81, 1003-1013 (2016), 2016 Polydimethylsiloxane (PDMS) is a widely used organosilicon polymer often employed in formulations with fine oxide particles for various high temperature applications. Although PDMS is considered to be thermally stable and chemically inert, it is not always clear how the oxide filler influences its thermoresistance, decomposition chemistry and what ...
