Convert CO2 into industrial products

Let us hope it goes into commercial production.

Closing the loop: Engineers want to convert carbon dioxide into industrial products

New technology that can convert carbon dioxide into chemical building blocks could see harmful emissions turned into industrial products.

Developed by Dr Rahman Daiyan and Dr Emma Lovell from the University of New South Wales (UNSW) School of Chemical Engineering, the process involves the production of zinc oxide nanoparticles through flame spray pyrolysis (FSP).

These nanoparticles then act as the catalyst for turning carbon dioxide into ‘syngas’: a mixture of hydrogen and carbon monoxide used in the manufacture of products such as fuel and plastics.

“Syngas is often considered the chemical equivalent of Lego because the two building blocks — hydrogen and carbon monoxide — can be used in different ratios to make things like synthetic diesel, methanol, alcohol or plastics, which are very important industrial precursors,” Lovell said.

“So essentially what we’re doing is converting CO2 into these precursors that can be used to make all these vital industrial chemicals.”

A new solution
While past attempts have used materials such as palladium, in their recent research the team used zinc oxide as a catalyst.

“This is the first instance where a very cheap and abundant material, mined locally in Australia, has been successfully applied to the problem of waste carbon dioxide conversion,” Daiyan said.

The use of the FSP flame system also means the new method is more easily scaled to the requirements of heavy industry.

“THIS IS THE FIRST INSTANCE WHERE A CHEAP MATERIAL, MINED LOCALLY IN AUSTRALIA, HAS BEEN SUCCESSFULLY APPLIED TO THE PROBLEM OF WASTE CARBON DIOXIDE CONVERSION.”
Dr Rahman Daiyan

“We don’t need to worry about complicated synthesis techniques that use really expensive metals and precursors,” Lovell said.

“We can burn it and in 10 minutes have these particles ready to go. And by controlling how we burn it, we can control those ratios of desired syngas building blocks.”

Closing the carbon loop
In the future, the technology could be scaled up for use in converting waste carbon dioxide emitted by a power plant, helping to close the carbon loop.

“The idea is that we can take a point source of CO2, such as a coal fired power plant, a gas power plant, or even a natural gas mine where you liberate a huge amount of pure CO2, and we can essentially retrofit this technology at the back end of these plants,” Lovell said.

“Then you could capture that produced CO2 and convert it into something that is hugely valuable to industry.”

So first they need to convert CO² to CO. No mention of the cost of conversion. But apparently it is scaleable unlike wind and solar generation. Then they need to manufacture Hydrogen which is not a part of CO², so another cost. Then they have syngas which presumably will be burned, creating CO² as a by-product.

And of course no mention of an efficiency factor.

BTW- The smoke? out of the stack is not CO² as that is colourless. It looks like water vapour.

You think lee is a socialist?

Haha...

Good one. You're so instantly triggered the moment anyone comments in reply and aren't 100% in support, even lee who is posting the real challenges about the idea but hoping it works.

We've been there before too, I support the idea of hydrogen as a fuel source (and because you're anti-solar so did you) but I brought up the challenges that are facing that technology and emerging industry and the hopes of them being overcome and you trolled me for a year until I started to ignore you...

You're worse than the snowflakes you claim to hate so much.

Now what the Socialist knockers and mockers HATE - more technical discussion which is all GREEK to them. It is all those BIG words.

Capturing Carbon's Potential: These Companies Are Turning CO2 into Profits
BY RENEE CHO |MAY 29, 2019

CO2 captured from power plants can be put to good use. Photo: Wikimedia Commons

On May 11, carbon dioxide levels in our atmosphere reached 415.26 parts per million for the first time in human history.

The last time CO2 levels were this high was probably 2.5 to 5 million years ago, when temperatures were 2 to 3˚C higher than today.

The Intergovernmental Panel on Climate Change (IPCC) has warned that we need to limit global warming to 1.5˚C to avert the most catastrophic effects of climate change.

This cannot be achieved, however, without removing CO2 from the atmosphere. Besides capturing carbon from fossil fuel plants directly, there are a variety of ways to remove CO2 from the atmosphere.

The problem is that many of these strategies are still relatively expensive. Finding new commercial uses for the captured CO2 is key to lowering the costs of these technologies and scaling them up.

Captured CO2 has long been injected into depleted oil fields to enhance oil recovery. It has also been pumped into greenhouses to boost plant growth.

But today, many companies and researchers are developing new uses and products for captured CO2, such as varieties of concrete, chemicals and fuels.

McKinsey & Company estimates that by 2030, CO2-based products could be worth between $800 billion and $1 trillion, and the use of CO2 for producing fuel, enriching concrete and generating power alone could reduce greenhouse gas emissions by a billion metric tons yearly.

The Global Carbon Initiative projects that, with the proper incentives, by 2030 the overall CO2 based product industry could utilize seven billion metric tons of CO2 each year—about 15 percent of our current global emissions.

“I think it [the CO2-based product sector] has very high potential and could be an important part of the climate mitigation tool kit,” said David Sandalow, a fellow at Columbia University’s Center on Global Energy Policy, an affiliate of the Earth Institute and co-author of a report on CO2 utilization.

“If we had genuinely marketable products using CO2, that could be transformational with respect to carbon capture technology. There are challenges, but I think with enough investment and enough commitment, many of those can be overcome.”

Now the technically literate NON Socialists can read on

Not strange at all. Humans are still emitting ADDITIONAL CO₂. just less of it

You always have struggled to understand the Carbon cycle Wink

Damn General you got me before I even said it.

I was about to say that this time you may know what you re talking about but them you just proved me wrong before I got to even say it.

It just goes to show you don't know schist. Grin

"Human sources of carbon dioxide are much smaller than natural emissions but they upset the balance in the carbon cycle that existed before the Industrial Revolution. The amount of carbon dioxide produced by natural sources is completely offset by natural carbon sinks and has been for thousands of years. Before the influence of humans, carbon dioxide levels were quite steady because of this natural balance.4 (

that is only if you believe nature has balance. Varying Ice Ages would seem to disagree with this statement.

)

42.84 percent of all naturally produced carbon dioxide emissions come from ocean-atmosphere exchange. Other important natural sources include plant and animal respiration (28.56%) as well as soil respiration and decomposition (28.56%).4 16 A minor amount is also created by volcanic eruptions (0.03%).17 18"

Of course if you can present an alternative view, backed up by peer review, have at it. Wink

This, after you were engaged in a technical discussion by someone who is far from a socialist, yet it still triggered you because it was discussing the technical challenges facing the idea you brought up and you then try to shut down the debate with personal attacks as if you're trying to create some sort of safe space?

Well done.
