The Difference

AbstractThe dehydrogenation of light alkanes, especially propane and butane, is widely exploited for the large-scale production of corresponding olefins. The industrial application of the direct dehydrogenation of light alkanes is limited due to reaction and thermodynamic constraints. The dehydrogenation of light hydrocarbons involves the breaking of two carbon–hydrogen bonds with the simultaneous formation of a hydrogen and carbon-carbon double bond selectively. It may appear to be simple, but their endothermic nature and selectivity control at higher temperature is difficult. The same technologies with minor changes in process and catalyst were used for the production of both propane and isobutane dehydrogenation. The economic analysis of the available technologies based on the specific consumption of feedstock, operational ease, and capital investment indicates an internal rate of return ~25%. The attractiveness of light alkane dehydrogenation is largely dependent on the difference in feedstock and the price of olefins produced. The available technologies and how they manage reaction constraints at commercial scale have been compared. The possible solution for improvement is by focusing on catalyst improvements and the unique design of reactors.

The study of phononic materials and structures is an emerging discipline that lies at the crossroads of vibration and acoustics engineering and condensed matter physics. Broadly speaking, a phononic medium is a material or structural system that usually exhibits some form of periodicity, which can be in the constituent material phases, or the internal geometry, or even the boundary conditions. As such, its overall dynamical characteristics are compactly described by a frequency band structure, in analogy to an electronic band diagram. With roots extended to early studies of periodic systems by Newton and Rayleigh, the field has grown to encompass engineering configurations ranging from trusses and ribbed shells to phononic crystals and metamaterials. While applied research in this area has been abundant in recent years, treatment from a fundamental mechanics perspective, and particularly from the standpoint of dynamical systems, is needed to advance the field in new directions. For example, techniques already developed for the incorporation of damping and nonlinearities have recently been applied to wave propagation in phononic materials and structures. Similarly, numerical and experimental approaches originally developed for the characterization of conventional materials and structures are now being employed toward better understanding and exploitation of phononic systems. This article starts with an overview of historical developments and follows with an in-depth literature and technical review of recent progress in the field with special consideration given to aspects pertaining to the fundamentals of dynamics, vibrations, and acoustics. Finally, an outlook is projected onto the future on the basis of the current trajectories of the field.
