[Editor’s Note: New research developments are coming that will make natural gas burn even cleaner than now, destroying fractivist arguments against it.]

Researchers at the University of Illinois Chicago have developed a cutting edge catalyst made up of 10 different elements–each of which on its own has the ability to reduce the combustion temperature of methane–plus oxygen. This unique catalyst brings the combustion temperature of methane down by about half, from above 1400 degrees Kelvin down to 600 to 700 degrees Kelvin. What it means is that natural gas can burn cleaner and emit far less carbon dioxide.

Once again science shows that fossil fuels like natural gas can be and are clean and just fine for the precious environment. And, fossil fuels are getting cleaner all the time with breakthroughs like the one outlined below. Rather than ban fossil fuels, reasonable people look to improve them. From ScienceDaily:

Natural gas is the cleanest traditional fossil fuel source because it produces relatively low amounts of pollutants like carbon dioxide — a potent greenhouse gas and major contributor to climate change. But greenhouse gases and pollutants released by burning natural gas could be reduced even further with the help of advanced catalysts that help lower the temperature at which methane — the largest component of natural gas — is burned.

“The more efficiently we burn methane and the less energy we use to burn it, the less greenhouse gas and pollutants it produces. So, anything we can do to get this combustion temperature down is an environmental win,” said Reza Shahbazian-Yassar, professor of mechanical and industrial engineering at the University of Illinois Chicago.

Shahbazian-Yassar and colleagues facilitated the development of a cutting edge catalyst made up of 10 different elements — each of which on its own has the ability to reduce the combustion temperature of methane — plus oxygen. This unique catalyst can bring the combustion temperature of methane down by about half — from above 1400 degrees Kelvin down to 600 to 700 degrees Kelvin.

Their findings are reported in the journal Nature Catalysis.

In previously-published research, Shahbazian-Yassar and colleagues demonstrated the ability to create multi-element nanoparticle catalysts, known as high entropy alloys using a unique shock-wave technique. Before this, materials scientists didn’t make serious attempts to create nanoparticles out of more than three elements because of the tendency of each elements’ atoms to separate from each other and become useless.

Taking advantage of the unique real-time, high-temperature electron microscopy system at UIC, Shahbazian-Yassar’s team showed that high entropy nanoparticles made up of 10 metal oxides were highly stable at temperatures up to 1,073 degrees Kelvin and the individual elements were distributed evenly throughout each nanoparticle forming a single, solid-state stable crystalline structure.

Their metal oxide alloy contained various mixtures of transition metals, which are rare-earth elements, and noble metals plus oxygen.

“It is almost impossible to maintain a perfect mix of these elements in a solid phase due to the differences in atomic radius, crystal structure, oxidation potential, and electronic properties of the elements,” said Zhennan Huang, a Ph.D. student in Shahbazian-Yassar’s lab and co-first author in the paper. “But we were able to show that this is possible.”

“Among multiple alloys with multiple elements that we created, the particles made of 10 elements not only were most effective in reducing the combustion point of methane gas but also the most stable at those temperatures,” said Shahbazian-Yassar, who is a corresponding author on the paper.

The researchers believe the catalyst could be used to reduce the output of harmful greenhouse gases produced by burning natural gas in individual households, to power turbines and even in cars that run on compressed natural gas.

We don’t have a full copy of the published research, and frankly, we wouldn’t understand it if we did. We do, however, have the abstract (below). The bottom line here is that we’re turning what is already a very clean fossil fuel into an even cleaner energy source. There’s no reason to dump natural gas from our national energy mix. Those who advocate for it are simply prejudiced or ignorant.

Here’s the abstract from the published research paper:

Oxide nanoparticles with elemental and structural diversity are widely studied for catalysis and energy applications. While compositional control holds great promise for materials discovery, current oxide nanoparticles are typically limited to a few cations due to the intrinsic complexity in nanoscale multi-element mixing. Here we report the rational design and synthesis of single-phase multi-element oxide nanoparticles with tunable composition, size and structure. We have identified temperature-, oxidation- and entropy-driven synthesis strategies to mix a range of elements with largely dissimilar oxidation potentials (including palladium), thus greatly expanding the compositional space. Through rapid synthesis and screening, we obtained a denary multi-element oxide catalyst showing high performance and superior stability for catalytic methane combustion over 100?hours due to the high-entropy design and stabilization. Our work therefore provides a viable synthesis route with clear guidelines for multi-element oxide nanoparticles and enables materials design in the multi-element space towards highly stable catalysts.

  1. This is a clear example of how adaptation, as always, if properly implemented can move us forward safely without stumbling headlong into inefficient (and not all that clean) solar and wind. In his excellent book, “False Alarm” by Bjorn Lomborg, he points out that the climate alarmists always point out worst! case scenarios to scare the living bejusus out of us, never conceding that adaptation, finding new ways to solve problems has always moved man forward. I highly recommend this book to everyone.
