Multiscale and Multiphase Model of Fixed Bed Reactors for Fischer-Tropsch Synthesis: Intensification Possibilities Study
(Amer Chemical Soc, Washington, 2017)
A multiphase fixed-bed reactor (FBR) model for Fischer Tropsch Synthesis has been developed. A high level of details is considered for description of the phenomena on the reactor and particle scale. Detailed kinetics is ...
Effects of Catalyst Activity, Particle Size and Shape, and Process Conditions on Catalyst Effectiveness and Methane Selectivity for Fischer-Tropsch Reaction: A Modeling Study
(Amer Chemical Soc, Washington, 2017)
We investigate effects of catalyst activity, catalyst particle shape (sphere, slab, and hollow cylinder), size (i.e., diffusion length), catalyst distribution (uniform vs eggshell type distribution for a spherical particle), ...
Modeling a Catalytic Reactor for Hydrotreating of Straight-Run Gas Oil Blended with Fluid Catalytic Cracking Naphtha and Light Cycle Oil: Influence of Vapor-Liquid Equilibrium
(Amer Chemical Soc, Washington, 2014)
Reducing the sulfur content of diesel fuels may require adjusted operation of low-pressure hydrotreater units. A mathematical model for co-hydrotreating of straight run gas oil blended with fluid catalytic cracking naphtha ...
Multiscale and Multiphase Model of Fixed-Bed Reactors for Fischer-Tropsch Synthesis: Optimization Study
(Amer Chemical Soc, Washington, 2018)
Our previously developed mathematical model is used for parametric sensitivity and optimization study of conventional and milliscale fixed-bed reactors (FBRs) for Fischer-Tropsch synthesis (FTS). Five indicators are chosen ...
Lipase-Catalyzed Esterification of Phloridzin: Acyl Donor Effect on Enzymatic Affinity and Antioxidant Properties of Esters
(Amer Chemical Soc, Washington, 2014)
Lipase-catalyzed acylation of phloridzin with a wide range of fatty acids and antioxidant activities of synthesized esters were investigated in this study. Polar solvents were suitable reaction media for esterification, ...
Influence of TEMPO-Mediated Oxidation on Properties of Hemp Fibers
(Amer Chemical Soc, Washington, 2012)
Hemp fibers are a very interesting natural material for textile and technical applications, but some of these applications require improved and/or specific fiber properties. In order to modify hemp fibers for obtaining ...
Degradation of the Insulating System of Power Transformers by Copper Sulfide Deposition: Influence of Oil Oxidation and Presence of Metal Passivator
(Amer Chemical Soc, Washington, 2010)
Deposition of conductive copper sulfide on paper insulation of power transformers was recognized as a serious risk that can result in equipment failure. The aim of this study was to investigate the influence of mineral ...
