They were produced and stabilized by Galvis, who affixed them to a special material. This made the catalyst more durable and made it a more efficient means for converting biogas into the bio-based building blocks, including ethylene and propylene. Process efficiency is a rate of about 60 percent lower olefins by carbon weight of the final products.
The catalyst's production depends on the Fischer-Tropsch synthesis, which has been used in the creation of fuels and chemicals, and is crucial in turning biomass into plastics. (You can access a video describing and illustrating this synthesis and its importance to the new catalyst here.)
The Utrecht University research team expects to continue developing the catalyst with the help of Dow Benelux. Still to be done are larger-scale testing and pilot projects. The team expects the first products made with the new technology to be launched over the next few years.
@Dave Palmer: I raised the Clear Air Act because we remain under its enforcement. I don't expect the increased use of oil and gas to cause energy producers to ignore it and begin to pollute. On the contrary, I think it would be better for folks who do observe the goals of the Clean Air Act to obtain and use resources responsibly, rather than leaving it to nations and others who do not.
In my world, Profit is a fantastic thing. It is the life's blood of innovation. Without Profit, there is only break-even status quo or decline. More Profit means increased Capital available for increased investment in more innovation. Profit is a measure of added value, not a measure of nefarious action.
And I agree wholeheartedly. It would be a much more efficient world if we all could point to a concept in Star Trek and rapidly advance the conversation... =]
This is old style FT with a new catalyst. I follow this closely as I want to make fuel from waste biomass that here in Fla you have to beat back continously or get over run.
As they said most any HC like celulose, coal etc can be reduced to H2 and CO then normal processes can be used to make whatever HC you want. Problems are catalysts that don't last, CO2 produced which is lost energy and heat losses. Both these losses can be used to make electricity to up system eff.
Biomass has a great advantage as it's far cleaner than coal which impurities posion the catalysts and cost a lot to remove before the syngas can be used in FT that biomass doesn't need, making biomass more eff.
Problem with most FT is the number of times you put the gas through before it converts. On biomass you need higher temps to keep junk alocohols, etc from forming instead of fuel, chemicals wanted.
All really needed for most anyone to do this is getting hold of good catalysts and their specs. I'd settle for the GTL cats Shell, others are using to make diesel from NG by way of syngas.
Too many cry we have an energy shortage when in fact there are huge ones all around. The only reason we are having problems is we only use oil, coal and now NG. If the full cost of oil, coal wa actually in them instead of in our taxes, healthcare costs, etc, their prices would double.
I don't like subsidies especially to big oil, coal which is the only reason we are not doing far more RE and even a more important resource, the energy not used by eff, insulation, great design, smart standards and realizing that one doesn't really need a 4000 lb car to move a 200lb person around or 2000sq' homes for 2 people, etc. Now a 2000sq' workshop I could see ;^P
No matter what there are now 4 B more people wanting oil, coal copper, iron, alum, plastics, etc and their share of the pie. The only way it will happen is if we get smart before it hits the fan which is already started with the Iraq war, the first of many until we get off oil. Iran seems next. Or fight over a dwindling supply. Far cheaper, better economy just switching and a lot less people die.
Plus once off of oil recessions will be a lot less often as 5 of the last 6 were oil recessions from oil proce shocks. Ever though about how much that costs? Oil companies get the gold mine and we get stuck with the costs.
It looks like plastics are fairly easy to turn back into diesel, gasoline. Most any biofat/oil , new or used can be made into biodiesel, Methane/NG easy by many methods means as prices rise on fossil fuels these will come out of the woodwork.
Wind, PV can now be had at competitive prices of $2-3/wt as could a home size CSP supplying both electric and heating/ hot water which is just an AC in reverse with a solar collector and about the same size, cost.
@williamlweaver: There's nothing wrong with someone making a profit, but there's nothing particularly noble about it, either. Markets are essentially amoral. Staying with the Star Trek theme, Exhibit A is Harry Mudd, Exhibit B is Cyrano Jones.
I agree about our treatment of soldiers and I agreee about politicians. Without politics, we could probably cut away half of our bases without losing any effectiveness. But base locations have become a form of pork.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
