Abstract:This project will develop a unique membrane reactor system for the production of tetrahydrofuran. In 2004 about 200 million kg of tetrahydrofuran were produced. The most widely used industrial manufacturing process for this chemical involves the acid-catalyzed dehydration of 1,4-butanediol. In many… more
Abstract:The conventional process for making dry tetrahydrofuran is very energy intensive because of the need for azeotropic distillation. Substituting distillation by membrane drying can reduce the energy consumption for heating by a factor of 50. A membrane based process for purifying tetrahydrofuran with… more
Abstract:Distillation is a very valuable chemical engineering unit operation but is energy intensive and capital intensive. This is especially true for removing water from organic and inorganic acids where components either form azeotropes or have small relative volatility differences. With a hybrid robust… more
Abstract:There continues to be a need for production of fuel-grade ethanol from renewable sources. Ethanol from agricultural sources has many advantages including development of fuel independence. While there continues to be a significant need for ethanol, the cost of agricultural based ethanol is quite… more
Abstract:Bio-oil is a liquid fuel made from biomass such as wood chips and low grade wood byproducts by fast pyrolysis process. Presence of carboxylic acids in raw-bio-oil makes the bio-oil very acidic and corrosive. Raw bio-oil has low heating value primarily because of its high water content (up to 35 %)… more
Abstract:In crude oil refining, asphaltenes are removed from heavy oil fractions to upgrade the quality of oil by solvent-deasphalting process. Solvents used in the solvent deasphalting process are recovered by either flash evaporation or super critical extraction. These conventional solvent recovery… more
Abstract:The membrane drying process for ethanol plants should be of great value in increasing capacity and/or reducing energy consumption for existing ethanol plants. We will manufacture modules of the novel membrane with a commercial partner. A pilot demonstration unit will be constructed and deployed at… more
Abstract:Industrial hydrogen production relies primarily on natural gas and hydrocarbon feedstocks to drive the various reaction chemistries that lead to hydrogen generation. Carbon dioxide, the ultimate co-product when such feedstocks and processes are employed, necessarily becomes a major contaminant of… more

Using biomass for production of fuels and chemical provides for a domestic, renewable and green route to address our fuel and chemical needs. This program provides a simple and inexpensive route for… more
Abstract:Ethylene and propylene are major chemical industry raw materials and consume a great deal of energy related to their production. Significant energy consumption is employed when cryogenically separating ethane from ethylene and propane from propylene. These cryogenic separations are difficult and are… more
Abstract:Optical components for RF-photonic applications such as communication satellites, avionics, optical networks, sensors and phase array radar will require high speed, high capacity and low power.

Silicon nanomembranes are single crystals of Si that… more
Abstract:Many large-scale numerical simulations can be broken down into common mathematical routines. While the applications may differ, they often need to perform standard functions such as system solves, Fourier transforms, or eigenvalue calculations. Consequently, producing fast, efficient implementations… more

Consequently, targeting fast, efficient implementations… more
Abstract:Optical CDMA is most suitable to be applied to high speed LAN to achieve contention-free, zero delay access, where traffic tends to be bursty rather than continuous. Channel assignment is much easier with CDMA. CDMA isolates irregular channels so that they do not influence other channels, CDMA can… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
