ALTERNATIVE SURFACTANT FORMULATION FOR NON-AQUEOUS PHASE LIQUID (NAPL) REMOVAL
Ide Seyni, Fatoumata (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 ... -
CARBOXYLIC ACID KETONIZATION ON ZEOLITES
Godavarthy, Manasa (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 ... -
CATALYTIC CONVERSION OF FURFURAL TO MORE UPGRADABLE PRODUCTS OVER BIFUNCTIONAL CATALYST
Herrera, Valeria (2017)Furanics are produced in high abundance from the decomposition of biomass. The thermal and chemical instability of these species leads to the formation of humins upon condensation. The ring rearrangement of furfural via ... -
Catalytic Hydrodeoxygenation of Phenolic Compounds of Importance in Bio-oil Upgrading
Nie, Lei (2014-05)Economic and environmental concerns including the increasing energy consumption and demand, ensuring energy security, reducing green-house gas emission and producing cleaner energy have caused tremendous interest in research ... -
CATALYTIC UPGRADING OF SUGAR DERIVATIVES
Jain, Diken (2016-08-12)With industrial revolution there has been a huge increase in demand for petroleum-based fuel. Detrimental effects on environment due to unprecedented use of fossil fuels and shortage in its availability has spurred the ... -
CHARACTERIZATION OF POLYETHOXYLATED ALKYL PHENOLS WITH A HIGH DEGREE OF ETHOXYLATION AT THE SOLID-LIQUID INTERFACE
Baker, Danielle Kimberly (2016-05)Fully characterizing the behavior of a surfactant, from the mechanism of adsorption to the formation of micelles, is vital when taking the surfactant out of the lab and into the real world. The critical micelle concentration, ... -
CONVERSION OF MODEL BIO-OIL COMPOUNDS OVER METAL OXIDES AND SUPPORTED METAL CATALYSTS
Omotoso, Taiwo (2015)Growing environmental concerns has necessitated the development of cleaner and renewable sources of energy such as biomass. Bio-oil derived from lignocellulosic biomass is a promising source for producing renewable chemicals ... -
CYCLOPENTANONE ALDOL CONDENSATION – EFFECTS OF SURFACE SILANIZATION, ACETONE AND WATER CO-FEEDING ON CATALYTIC BEHAVIORS OF MAGNESIUM OXIDE-BASED SOLIDS
Ngo, Duong (2018)Cyclopentanone is a promising building block in the conversion of biomass to fuels. It can be readily obtained from furanics derived from biomass and can be converted to intermediate products in the molecular weight range ... -
DESIGN OF SOLID ACID CATALYSTS FOR BIOMASS UPGRADING VIA C-C COUPLING AND DEHYDRATION REACTIONS
bui, tuong (2018-12-14)Furanics fraction has been a major obstacle that impedes the feasibility of practical upgrading of bio-oil. The high reactivity of species existing in the mixture favors humins formation via polymerization. This leads to ... -
A DFT STUDY OF THE CATALYTIC HYDRODEOXYGENATION OF ANISOLE ON A RHODIUM CATALYST
Aruho, Darius (2018-05)Heterogeneous catalysis is an integral part of chemical industry. Additionally, the surge in biomass research has necessitated a need for newer and effective catalysts to upgrade biomass and its constituents: - lignin, ... -
DFT-Derived Location and Hydroxide Coordination of Lanthanum Ions in Zeolite Y Structures
Crouch, Jacob (2021-08-05)Fluid Catalytic Cracking is a process of great interest in oil refining. This process is governed by the stability and activity of acid sites held within zeolite frameworks. Rare earth exchanged, specifically lanthanum ... -
Diffusional constraints implications in C-C reactions over Brønsted acid sites
