Production of hydrogen by thermal methane splitting in a nozzle-type laboratory-scale solar reactor

Chirality-controlled synthesis of single-wall carbon nanotubes using vapour-phase epitaxy

“…There is a large body of literatures covering extensive studies on the pyrolysis process. To simplify our discussion and without loss of generality, we focus on the methane case [30][31][32] . Overall, pyrolysis of methane can be described by the reaction CH 4 -C (solid) þ 2H 2 .…”

Low-carbon production of hydrogen from fossil fuels

“…The application of solar aerosol technology to hydrogen production from liquid hydrocarbons (C7eC8) was reported by Ma, Lall, Aronhime, and Zachariah (2010). The highest hydrogen yield of 81% was obtained for n-octane at 1050 C. Abanades and Flamant (2005) reported a nozzle-type solar reactor for thermal methane decomposition. In the solar reactor, a nozzle made of graphite absorbed concentrated radiation provided by a 2-m-diameter solar furnace, and the absorbed heat was then transferred to the reagents.…”

Transient heat transfer simulation of a 1kWth moving front solar thermochemical reactor for thermal dissociation of compressed ZnO

“…The simulated solar concentrator is located at PROMES-CNRS laboratory and consists of a 2 m-diameter parabola with 0.85 m-focal distance, 120 • aperture, optical error of 3.1 mrad and maximal total thermal power of 1.4 kW delivered at the focal point ( Fig. 2) (Abanades and Flamant, 2005;Villafán-Vidales et al, 2012). In this part of the MC code, the reflection points on the concentrator surface are chosen with random numbers and with millions of them, the reflection points gradually cover uniformly the entire concentrator surface.…”
