ALTERNATIVE SURFACTANT FORMULATION FOR NON-AQUEOUS PHASE LIQUID (NAPL) REMOVAL
(2016-05)
Due to the inefficiency of the pump and treat method in removing hydrocarbon contamination from ground water, a new method called surfactant Enhanced Aquifer remediation (SEAR) has been developed. SEAR is just a chemical ...
Melt Blowing with Louvers and their Effects on Fiber Attenuation and Motion
(2017-12)
A physical plateau in the air field below a melt blowing die was imposed by airfoil shaped louvers. These louvers prevented air jet spreading and imposed a constant average air velocity on the polymer filament, resulting ...
CARBOXYLIC ACID KETONIZATION ON ZEOLITES
(2016-05)
Carboxylic acids contained in crude oil and bio oil present significant corrosion and handling problems. It is necessary that the acid content is reduced in the bio-oil for upgrading. One potential method is to convert ...
QUANTIFICATION OF NON-IDEAL MIXING IN SODIUM DI (2-ETHYLHEXYL) SULFOSUCCINATE – ANIONIC SURFACTANT MIXTURES
(2017-05)
HLD equation was first introduced by Salager [1], however for predicting the HLD parameters from known parameters of a surfactant in a binary anionic-anionic mixture, Acosta [8] suggested linear mixing rules which can be ...
CARBON NANOTUBES AND MAGNETIC PARTICLES AS PICKERING EMULSION STABILIZERS: PARTICLE CONTROL FOR PHASE SELECTIVE REACTIONS
(2016-05-13)
Interest in the use of two phase reaction systems for the production of biofuels and specialty chemicals from biomass has been increasing over the past several years, specifically in circumstances in which the feedstock ...
A Molecular Dynamics Simulation Study of the Hydrogen Bond Networks in Water-Glycerol Mixtures
(2019-05-11)
Molecular Dynamics simulations are performed over a wide range of water-glycerol concentrations to observe the intermolecular hydrogen bond (H-bond) populations at each concentration. The measured values from simulations ...
Water Enhancement of Hydrocarbon Cracking Reactions on ZSM-5
(2019-07)
Catalytic cracking of hydrocarbons is an extremely important process for the production of fuels and commodity chemicals from petroleum feedstocks. The effects of water on these reactions has been studied before at high ...
EFFECT OF BIOMASS COMPOSITION ON HEMICELLULOSE, CELLULOSE, AND LIGNIN DERIVED THERMAL PRODUCTS VIA TORREFACTION/PYROLYSIS
(2019-07-25)
Modern industrialization has resulted in an ever-increasing demand for petroleum-based fuel production and electricity generation. Exploitation of fossil fuel reserves have, however, raised grave environmental concerns due ...
HEXANE CRACKING ON Y ZEOLITES: ACTIVITY ENHANCEMENT AND ITS POSSIBLE REASONS
(2016)
HY zeolites are an essential component as catalysts in fluidized catalytic cracking (FCC) process. The Steamed HY or Ultra Stable Y (USY) zeolites have proved to be active hydrocarbon cracking catalysts. Therefore, in this ...
SELECTIVE CONVERSION OF UNSATURATED CARBOXYLIC ACIDS TO OLEFINS OR DIOLEFINS
(2018-05-12)
Biomass is composed of pentosans and hexosans that can be converted to γ-valerolactone (GVL) via an acid-catalyzed dehydration and metal-catalyzed hydrogenation reactions.16,17 Through acid catalysis, GVL can undergo ...
