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 ...
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 ...
CATALYTIC UPGRADING OF SUGAR DERIVATIVES
(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 ...
ENHANCEMENT OF ZEOLITE CATALYZED REACTIONS FROM WATER CLUSTERS AND BRONSTED SITE PROXIMITY
(2018)
Zeolites offer many benefits as a catalyst. The adjustable acid sites in zeolites and its well-defined pore structure allows for a fine-tuning of the catalytic performance. The activity and selectivity of several reactions ...
Adsorptive Trapping of Bio-oil Compounds onto Activated Carbon
(2016-08)
Industrialization and its long-term effects on the environment are receiving increased scrutiny from both political and environmental pundits questioning environmental sustainability in a time of globalization. Traditional ...
FUNCTIONALIZATION OF MESOSTRUCTURED SILICA CATALYSTS TO IMPROVE STABILITY AND DECREASE LEACHING DURING C-C BOND FORMING REACTIONS IN THE LIQUID PHASE
(2017-08-01)
The ordered mesoporous silica materials such as MCM-41 and SBA-15 have raised special attention because of its chemical and thermal stability. Several studies have been reported the ubiquitous modification method of the ...
The Development of a Combined Approach for the Real-Time, Non-Destructive Monitoring of In Vitro Bone Tissue Engineered Constructs Utilizing Physio-Metabolic Markers
(2016-08)
Annually, over $2.5 billion is spent on more than 500,000 bone grafts in the US alone, with more than 2 million being implanted worldwide. The limited supply of autografts and complications associated with traditional ...
