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...

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...

Desulfurization of thiophene and dibenzothiophene with hydrogen peroxide in a photochemical microreactor

Creator:: Al-Raie, Ali H.
Abstract:: Sulfur content of fuels and desulfurization of fuels is becoming an important environmental restriction and regulatory issue. In this study new technology for the desulfurization of fuels is considered. Micro scale reactors are introduced for desulfurization of thiophene and dibenzothiophene. Thiophene and dibenzothiophene are mixed with hexane at concentration, C₀...

Chemical Reaction Processes in Microscale-Based Reactors; Mathematical Model and Numerical Simulation of the Fischer-Tropsch Process and Activation of Methane in a Corona Discharge Plasma Reactor

Creator:: Traverso, Andrew C.
Abstract:: Worldwide production of natural gas has surged in the last few decades leading to an economic windfall for many communities, but sometimes these new sources of natural gas are located in geographically isolated locations. These areas are so remote that it isn’t economically feasible to transport this stranded gas to...

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...

Membrane and micro-sparging aerations in long-term high-density perfusion cultures of animal cells

Creator:: Qi, Hanshi
Abstract:: The profile of the inner-tubing gas pressure for a tubular membrane aeration system was quantified. The correlations among the overall volumetric oxygen transfer coefficient (k[subscript L]a), the inner-tubing pressure, the tubing tightness, and the gas throughput are experimentally analyzed. A mathematical model was developed to describe the underlying phenomena. The...

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...
