Researchers at Nanjing Tech University in China have developed a new pathway for the production
of liquid hydrocarbon fuels from lignocellulose.
Not exact matches
Gasoline is a petroleum - derived
liquid mixture consisting primarily
of hydrocarbons, used as
fuel in internal combustion engines.
A team
of University
of Texas at Arlington chemists and engineers have proven that concentrated light, heat and high pressures can drive the one - step conversion
of carbon dioxide and water directly into useable
liquid hydrocarbon fuels.
Oxidation
of hydrocarbon to CO2 releases about 478 kJ / mol C. That's the minimum amount you need to reduce CO2 to
liquid fuel assuming perfect conversion.
So, apparently, if I understand this correctly, the idea is really about a way that actually requires an independent source
of energy (and a big one) in order to make
liquid fuels and other
hydrocarbon - based products in a relatively «carbon - neutral» way.
Plenty
of coal to run high tech civilization at least another hundred years even with substantial economic growth by burning it in conventional coal - fired electric plants and making
liquid hydrocarbon automotive
fuels from it.
The team at Air
Fuel Synthesis (AFS) has created a system for using renewable energy to power the capture
of CO2 and water, which is then transformed into
liquid hydrocarbon fuels that can be used directly in gasoline engines.
So, if you could create
liquid hydrocarbons that are compatible with gasoline cars, then the adoption cycle would be a lot easier than switching over to electric or hydrogen or some other type
of fuel for cars.
Apparently there are a lot
of people who seem to like that hippy commune style
of living, and feel free, don't let me stop you, but I want the Jetson's, I want humans to become a spacefaring race, we need to mine the asteroid belt, and someday travel to the stars, but in the mean while there are oceans
of liquid hydrocarbons (though not very practical as a home heating
fuel, I realize) and boulders
of platinum group metals out there to go get.
When used as a source
of energy to manufacture
hydrocarbons such as methane and
liquid fuels, as you point out solar panels can only do this in the daytime.
The production
of liquid fuels from coal will very likely become an important part
of the
hydrocarbon energy mix
of the future, provided that technical and environmental obstacles are overcome economically.
Peter, the amount
of carbon one requires to replace
liquid hydrocarbon fuels is huge, the levels
of DIC are low and so one would require staggering amounts
of sea water and would discharge staggering amounts
of carbon denuded sea water.
Publication date: 2009-06-01 First Published: Natural Resources Research Authors: R.C. Milici Abstract: The production
of liquid fuels from coal will very likely become an important part
of the
hydrocarbon energy mix
of the future, provided that technical and environmental obstacles are overcome economically.
A Berkeley Lab - led team is working to re-engineer an enzyme for the efficient conversion
of methane to
liquid hydrocarbon transportation
fuels.
Adding insult to injury electricity, even were it free to produce at centralized generation facilities, can not practically replace
liquid hydrocarbon fuels for lack
of distribution capacity to local consumption and lack
of storage capacity for transportation.
To get
liquid fuel from gas, CO2 needs to be broken up so as to extract the carbon atoms in order to make new
hydrocarbons (the building blocks
of fuel).
Some
of those, such as octane, are drop - in replacements for existing
liquid hydrocarbon fuels.
Of course, to me the ideal answer is direct solar power →
Fuel, such as methane (to replace natural gas) or
liquid hydrocarbons (to replace fossil).
