The mechanism of char ignition in fluidized bed combustors [PDF]

, 1987
Knowledge about ignition processes of coal in fluidized beds is of importance for the start-up and dynamic control of these combustors. Initial experiments in a transparent fluidized bed scale model showed the existence of a considerable induction period

Thermochemical properties and regularities of amides, anilides, and amidic acids

Acta Chimica Slovenica, 2018
The thermodynamic properties of carbamide and its alkyl substituted were studied insufficiently. In this article, the enthalpies of combustion of ΔсН of some amides, anilides and amidic acids have been determined experimentally; their standard enthalpies

Thermodynamics of Chemical Hydrogen Storage: Are Sterically Hindered and Overcrowded Molecules More Effective?

Applied Sciences, 2023
Homocyclic aromatics with different degrees of alkylation have been investigated so far as Liquid Organic Hydrogen Carriers (LOHC). A low enthalpy of reaction for the dehydrogenation reaction is generally considered beneficial.
