... for the storage reactor is established and solved with the Finite Element Method. The reactor concept with direct heat transfer by flowing the gaseous reactant plus additional inert gas through the solid reactants did not show any limitation due to heat transfer. If reaction kinetics are fast enough, the reactor...

... media promises enhanced stability to solar transients and faster reaction rates. The present study establishes and compares the reaction kinetics of pyrolysis and gasification of cellulose from 1124 K to 1235 K in an electric furnace. Data are presented in an inert environment and in a bath of a ternary...

... solar energy. The continuity, momentum, and energy governing equations that couple the rate of heat transfer to the Arrhenius-type reaction kinetics are formulated for an absorbing-emitting-scattering particulate media and numerically solved using a computational fluid dynamics code. Parametric...

... ]. As noted above, significant residual amounts of graphite, that was found after terminating the reaction, is evidence of this. Simultaneously, no residue of the loaded ZnO was found except for ZnO from the back reaction (kinetics of back reaction was carefully studied in ( 14 ) and different kinds of ZnO...

... development utilizes previous and on-going experimental work on volumetric receiver and catalyst development. The reaction’s kinetics are computed, using the CHEMKIN II simulation package. The chemical kinetic modeling of the relevant C-H-O system is based on: (i) Definition of the relevant computation domain...

... thermodynamics reaction kinetics Atmospheric nitrogen fixation is a direct reaction between nitrogen and oxygen in standard air or in oxygen-enriched air (e.g., a composition of 50 %   N 2 and 50 %   O 2 ) to produce nitric oxide (NO). This reaction requires temperatures...
