The thermodynamics and kinetics of clathrate hydrate formation processes are topics of high scientific interest, especially in the petroleum industry. Researchers have made efforts at understanding the underlying processes that explicate the macroscopic observations from experiments and other research methods of gas hydrate formation. To achieve this, they have employed theories founded upon force related intermolecular interactions. Some of the theories and concepts employed include hydrogen bonding, the Leonard Jones force principle, and steric interactions. This paper gives a brief review of how these intermolecular interaction principles have been understood, and used as tools, in explaining the inaccessible microscopic processes, that characterize clathrate hydrate formation. It touches upon nucleation, growth, and inhibition processes.

AbstractIn order to understand the pre-reduction behaviour of fine hematite particles in the HIsarna process, change of morphology, phase and crystallography during the reduction were investigated in the high temperature drop tube furnace. Polycrystalline magnetite shell formed within 200 ms during the reduction. The grain size of the magnetite is in the order of magnitude of 10 µm. Lath magnetite was observed in the partly reduced samples. The grain boundary of magnetite was reduced to molten FeO firstly, and then the particle turned to be a droplet. The Johnson-Mehl-Avrami-Kolmogorov model is proposed to describe the kinetics of the reduction process. Both bulk and surface nucleation occurred during the reduction, which leads to the effect of size on the reduction rate in the nucleation and growth process. As a result, the reduction rate constant of hematite particles increases with the increasing particle size until 85 µm. It then decreases with a reciprocal relationship of the particle size above 85 µm.
