Three Cullen College chemical engineering Ph.D. students have returned from Denver, Co. where they were special guests at the 25th North American Meeting (NAM25) of the North American Catalysis Society. Sashank Kasiraju, who studies under the direction of Assistant Professor Lars Grabow, Wendy Lang, who studies under Mike Harold, chair of chemical and biomolecular engineering and Wei Qin, mentored by Jeff Rimer, Ernest J. and Barbara M.
Though the Society for Automotive Engineers (SAE) once boasted an active University of Houston student chapter, the organization has been dormant on the UH campus for several years. Now, a group of dedicated Cullen College of Engineering students are bringing the student organization back to campus and into the fast lane – literally.
William Epling, associate professor of chemical and biomolecular engineering at the University of Houston Cullen College of Engineering, was featured in a Q&A session with FuelFix regarding natural gas use in vehicles on December 22, 2013.
One of the ironies of automobile research: as diesel engines become more fuel efficient, reducing their emissions becomes more challenging.
Better efficiency means that more of the energy in diesel fuel is being used to move the vehicle and less is escaping out the tailpipe in the form of heat. While this is undoubtedly good, it presents a challenge for emissions reduction.
When analyzed from the oil well to wheels on the ground, diesel is the single most efficient liquid transportation fuel. Combine that with rising petroleum prices and concerns about peak oil production, and it is clear that there is a real and growing need to improve efficiency and reduce emissions from diesel-powered vehicles.
The Cullen College's Texas Diesel Research and Testing Center was founded, in part, to develop technologies that reduce emissions from diesel vehicles. Researchers at the center have worked to cut pollution from everything from school buses to garbage trucks to heavy construction equipment. Thanks to a recent $163,000 grant, it can now add one more vehicle to that list: commercial fishing boats.
Using a $1 million grant from the U.S. Environmental Protection Agency, the Texas Diesel Testing and Research Center at the University of Houston will retrofit Houston Independent School District school buses with a system that attempts to diminish the negative impact their diesel emissions can have on the environment. UH researchers will supervise the installation of Nett Technologies’ BlueMAX Selective Catalytic Reduction System on buses.

Inside the University of Houston Texas Diesel Testing and Research Center, space is typically reserved for finding ways to clean harmful pollutants from diesel vehicle exhaust through retrofit systems attached to tailpipes.
But recently, diesel center researchers have taken on a new project intended to expand the center’s clean air focus. They are examining glass beakers filled with samples of a slimy green substance most find growing in ponds, swamps and even dirty swimming pools.
Diesel engines are the workhorses of American economy, powering everything from heavy-duty construction vehicles and buses to ships.
These engines are also one of the biggest producers of harmful pollutants, churning out more smog-causing Nitrogen Oxides (NOx) and near 100 times more sooty particles than their gasoline counterparts.
The Texas Diesel Testing and Research Center at the University of Houston recently finished an expansion doubling its size and increasing its means to research and test retrofit devices that reduce the amount of harmful pollutants emitted from heavy-duty diesel engine exhaust.
UH’s Diesel Vehicle Research and Testing Facility, initiated in advance of the Bush administration’s Clean Air Nonroad Diesel Rule signed by the EPA in May, will be unveiled to the public during a ribbon-cutting ceremony with Houston Mayor Bill White at 3 p.m., Monday, June 28.
At Houston’s newly-developed Diesel Vehicle Research and Testing Facility today, EPA Regional Administrator Richard E. Greene announced the Bush administration’s Clean Air Nonroad Diesel Rule will cut emission levels from construction, agricultural and industrial diesel engines by more than 90 percent. The rule was signed by EPA Administrator Mike Leavitt yesterday.
