U of M discovery to improve efficiencies in fuel, chemical and pharmaceutical industries

29.06.2012
Breakthrough could reduce costs for the consumer

University of Minnesota engineering researchers are leading an international team that has made a major breakthrough in developing a catalyst used during chemical reactions in the production of gasoline, plastics, biofuels, pharmaceuticals, and other chemicals. The discovery could lead to major efficiencies and cost-savings in these multibillion-dollar industries.

The research is to be published in the June 29, 2012 issue of the leading scientific journal Science.

"The impact of this new discovery is enormous," said the team's lead researcher Michael Tsapatsis, a chemical engineering and materials science professor in the University of Minnesota College of Science and Engineering. "Every drop of gasoline we use needs a catalyst to change the oil molecules into usable gasoline during the refining process."

This research improves efficiencies by giving molecules fast access to the catalysts where the chemical reactions occur. Tsapatsis compared it to our use of freeways and side streets in our daily lives.

"It's faster and more efficient to use freeways to get where we want to go and exit to do our business compared to driving the side streets the entire way," he explained. "The catalysts used today are more like all side streets. Molecules move slowly and get stuck. The efficiencies of these new catalysts could lower the costs of gasoline and other products for all of us."

The research team built their prototype of the new catalyst using highly optimized ultra-thin zeolite nanosheets. They used a unique process to encourage growth of these nanosheets at 90-degree angles, similar to building a house of cards. The house-of-cards arrangement of the nanosheets makes the catalyst faster, more selective and more stable, but can be made at the same cost (or possibly cheaper) than traditional catalysts.

With faster catalysts available at no extra cost to the producer, production per manufacturing dollar will increase. With a higher output, it is conceivable that consumer costs will drop.

This new discovery builds upon previous discoveries at the University of Minnesota of ultra-thin zeolite nanosheets used as specialized molecular sieves for production of both renewable and fossil-based fuels and chemicals. These discoveries, licensed by the new Minnesota start-up company Argilex Technologies, are key components of the company's materials-based platform. The development of the new catalyst is complete, and the material is ready for customer testing.

"This breakthrough can have a major impact on both the conversion of natural gas to higher value chemicals and fuels, and on bio- and petroleum refiners," said Cesar Gonzalez, CEO of Argilex Technologies. "Using catalysts made by this novel approach, refiners will be able to obtain a higher yield of desirable products such as gasoline, diesel, ethylene and propylene. At Argilex, we envision this catalyst technology platform to become a key contributor to efficient use of natural resources and improved economics of the world's largest industries."

Researchers on the team are from around the globe. In addition to the University of Minnesota, researchers are from institutions in Tokyo, Abu Dhabi, Korea and Sweden.

Primary funding for this research is from the U.S. Department of Energy's Center for Catalysis and Energy Innovation, an Energy Frontier Research Center. The University of Minnesota is a partner in this multi-institutional research center at the University of Delaware. Other funding for this research is from the National Science Foundation Emerging Frontiers in Research and Innovation Program, the University of Minnesota's Initiative for Renewable Energy and the Environment, and the Abu Dhabi-Minnesota Institute for Research Excellence (ADMIRE) partnership between the University of Minnesota and the Abu Dhabi Petroleum Institute.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
