A novel lattice Boltzmann method for treatment of multicomponent convection, diffusion, and reaction phenomena in multiphase systems

Creator:: Parker, James Muirhead
Abstract:: In this work, a multicomponent lattice Boltzmann model is developed for the simulation of multiphase mixing, reactions, and separations processes. This model is unique in that diffusive mass transfer of a component in the model is driven by gradients of chemical potential. This fundamentally correct description of diffusion accurately captures...

Modeling Study of the Effects of Catalyst Support on Bio-Hydrogenated Diesel Production Using Density Functional Theory

Creator:: Huang, Dan
Abstract:: The catalyst support effect on NiMoS of bio-hydrogenated diesel production was investigated via density functional theory. The activity, stability and selectivity of catalyst on three widely used catalyst supports (Al2O3, TiO2 and SiO2) were studied and compared. Catalyst-support interaction and Brønsted acidity strength of different catalyst supports were characterized, which...

Deep desulfurization of diesel fuel using a single phase photochemical microreactor

Creator:: Jones, Jacob Aaron
Abstract:: There is an urgent need to lower the concentration of sulfur in diesel fuels. Growing concern over environmental effects caused by burning sulfur-containing diesel has led the world to higher standards in fuel refinement. Because of these lower standards, many techniques have been researched to remove sulfur containing compounds or...

CO2 reduction in aqueous-ionic liquid solution in microscale-based corona reactor, CO₂ reduction in aqueous-ionic liquid solution in microscale-based corona reactor

Creator:: Miao, Yu
Abstract:: Global warming problem is becoming an increasingly important environmental concern and CO₂ is considered as the major cause of global warming. Among various methods of CO₂ utilization, conversion of CO₂ to value added chemical products is the most attractive. In this study, a microscale-based corona reactor is introduced for reduction...

Performances and kinetic studies of hydrotreating of bio-oils in microreactor

Creator:: Attanatho, Lalita
Abstract:: Hydrotreating reaction of vegetable oil is an alternative method for the production of renewable biodiesel fuel. This reaction involves conversion of triglycerides into normal alkanes, leads to a deoxygenated and stable product, which is fully compatible with petroleum derived diesel fuel. The hydrotreating process uses hydrogen to remove oxygen from...

Photochemical reduction of carbon dioxide in aqueous and ionic liquid solutions in a microreactor with TiO₂ catalyst; experiment and modeling

Creator:: Campbell, Travis J.
Abstract:: Microtechnology was used to study the chemical reduction of dissolved carbon dioxide into useful products. A novel TiO₂ photocatalyst was used to activate the reaction under ultraviolet irradiation. CO₂ was dissolved in aqueous and 50% BMIM-BF₄ (ionic liquid) solutions. The introduction of an ionic liquid increased the solubility of CO₂...

Numerical study of mass transfer enhanced by theromocapillary convection in a 2-D microscale channel

Creator:: Kittidacha, Witoon
Abstract:: The effect of unsteady thermocapillary convection on the mass transfer rate of a solute between two immiscible liquids within a rectangular microscale channel with differentially heated sidewalls was numerically investigated. A computational fluid dynamic code in Fortran77 was developed using the finite volume method with Marker and Cell (MAC) technique...

Hydrodynamic effects of particle chaining in liquid-solid magnetofluidized beds : theory, experiment, and simulation

Creator:: Cruz-Fierro, Carlos Francisco
Abstract:: In a fluidized bed of magnetically susceptible particles, the presence of a magnetic field induce the formation of particle chains due to interparticle magnetic forces. The resulting effect is a change in the overall spatial distribution of the particles, transitioning from a random, isotropic distribution to an ordered, anisotropic distribution....
