Molecular weight drives a series of solutions that may provide keys to driving down production costs and harvesting a century’s worth of natural gas

WEST LAFAYETTE, Ind. – It is a figure that has been thrown around quite a bit lately in the energy debate – the United States has enough energy in shale to provide all of the nation’s transportation fuels for 100 years. But two challenges remain – how to tap into that supply and how to process it into fuel at a reasonable price.

Now, a research team at Purdue University has come up with a series of patented solutions that may help address those hurdles. The team has developed a two-step process to convert shale natural gas to liquid fuels such as gasoline and diesel. Current processes are capital-intensive with high operating costs.

“We have come up with a portfolio of technologies to address this problem,” said Jeffrey Miller, a professor in Purdue’s Davidson School of Chemical Engineering. “It is important because the U.S. is sitting on this massive and secure energy supply and a potential of greater than about $25 billion per year market if a successful process can be commercialized.”

Shale gas molecules present production problems for oil refineries because they are much lighter than oil molecules and require a different production process. Miller said the Purdue team developed a catalytic process that uses less energy when compared to existing technologies, and also created improved catalyst structures for both process steps.

“Another challenge in dealing with the light shale gas hydrocarbons is that they are typically located in areas of the U.S. that are far from heavily populated cities and expensive to transport,” Miller said. “So, our higher molecular weight products are economically transported to existing refineries where they can be processed to transportation fuels.”

The researchers worked with the Purdue Office of Technology Commercialization to patent their innovations.

Their work aligns with Purdue’s Giant Leaps celebration, celebrating the global advancements in sustainability as part of Purdue’s 150th anniversary. Sustainability is one of the four themes of the yearlong celebration’s Ideas Festival, designed to showcase Purdue as an intellectual center solving real-world issues.

Miller and his team work closely with Purdue’s Center for Innovative and Strategic Transformation of Alkane Resources, a National Science Foundation Engineering Research Center bringing together experienced academic teams of professors and graduate students from Purdue, the University of New Mexico, Northwestern University, the University of Notre Dame and the University of Texas at Austin.

The Purdue Office of Technology Commercialization operates one of the most comprehensive technology transfer programs among leading research universities in the U.S. Services provided by this office support the economic development initiatives of Purdue University and benefit the university’s academic activities.

The office is managed by the Purdue Research Foundation, which received the 2016 Innovation and Economic Prosperity Universities Award for Innovation from the Association of Public and Land-grant Universities.
