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 ...
Temperature Swing Solvent Extraction for Selenate and Selenite Removal from Industrial Wastewater
(2022)
Coal-fired power plants provide more than one fifth of the electricity generated in the United States. Flue gas desulfurization (FGD) of the products of coal combustion is necessary to prevent emissions of SO2, which is ...
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 ...
Adsorption of Biomass Torrefaction Vapors on Activated Carbon
(2017-12)
Energy is a growing need for the modern economy; however, global reliance on nonrenewable resources is problematic. The United States transportation infrastructure in particular was built around the combustion of petroleum ...
Catalytic dehydration of poly (vinyl alcohol-co-ethylene) with heterogeneous acid catalysts
(2023)
This study investigates the role of acid site density, pore size, and solvent selection in the
catalytic dehydration of Poly (vinyl alcohol-co-ethylene) (EVOH) using zeolite catalysts. The first
set of experiments ...
