A link, established between the classic excess Gibbs free energy expressions and conventional mixture models, allowed the extension of the Margules and van Laar models to multicomponent mixtures. It is shown that the multicomponent form of the classi

Jet fuel is a mixture of different hydrocarbon groups, and the mass contribution of each of these groups toward the overall chemical composition of the fuel dictates the bulk physical properties of the fuel after completion of the refining and blendi

Mixture experiments in which linear constraints are imposed on the components of the mixture are used extensively in practice. The problem of constructing designs which are in some sense optimal for this experimental setting is not straightforward. M

In the chemical industry C2–C4 olefins are critical building blocks for high value commodity products. One of the key challenges in Fischer Tropsch Synthesis (FTS) technology development is to manipulate process conditions and/or catalytic systems

Cobalt-based Fischer–Tropsch (FT) catalysts typically contain reactive cobalt metal nanoparticles on support materials. Such metal nanoparticles are expected to have properties that are strongly size-dependent. Noting the size-dependence of the Co

The amount of gas produced from a coal gasification facility depends crucially on the properties and the size distribution of the coal being used in the process. The particle size distribution and the composition of the coal are measured as compositi
