TL;DR: In this article, it was shown that the volume fraction of the lighter component in the lower layer is constant regardless of the bulk bed composition, and that layer inversion occurs for a given particle mixture when the liquid velocity passes through a value at which the volume of the thinner component in lower layer becomes equal to the larger component in upper layer.

TL;DR: In this paper, a theoretical model to predict relationships between the bulk composition and the critical velocity for complete mixing is developed on the basis of momentum equations for each particle component, independently given from a unit cell model with assumptions of creeping flow around the particle within the fictitious spherical cell and of a potential flow outside the cell.

TL;DR: Information needed to characterize Hg oxidation in coal-derived exhausts is now evident: complete gas compositions, hydrocarbons, H2O, O2, NOx, SOx, UBC properties, and the ash partitioning throughout the exhaust system are required.

TL;DR: In this article, the authors investigated the possibility of effective hydrogen production from food waste and found that the ash contained large amounts of alkali components has the effect of increasing the hydrogen production and shifting steam gasification conditions to lower temperature.

TL;DR: In this article, a laboratory-scale pulverized coal flame generated exhausts from five coals which were processed at realistic quench rates and residence times with typical flyash loadings.
