Technology Review is highlighting the efforts of Colorado - based Sundrop Fuels to develop a system which uses the heat of the sun to vaporize biomass and turn
it into syngas: The system consists of a gasifying unit mounted on top of tower surrounded by solar concentrating mirrors which reflect sunlight back to the gasifier and heats its ceramic tubes to 1,200 - 1,300 °C.
Awardees will receive approximately $ 16 million to advance the gasification process, which converts carbon - based materials such as coal
into syngas for use as power, chemicals, hydrogen, and transportation fuels.
As the biomass is dropped through the intensely hot ceramic tubes, it is vaporized
into syngas.
Instead, the fibrous materials are heated through pyrolysis (heating in the absence of oxygen) and results in the production of a liquid oil that is then refined
into syngas.
However, through careful regulation of the oxidant flow, the coal does not burn but rather separates
into the syngas.
Gasification converts all of
it into syngas, which can then be used to make a wide variety of chemicals, including methanol, ethanol, or diesel.
Awardees will receive approximately $ 16 million to advance the gasification process, which converts carbon - based materials such as coal
into syngas for use as power, chemicals, hydrogen, and transportation fuels.
By 2012 this should fall to $ 1.33 — at least for those companies using steam to turn biomass
into syngas (several firms, he says, have developed this technology).
Heat and catalysts converted methane
into syngas (carbon monoxide and hydrogen) which were then transformed into liquid hydrocarbons (otherwise known as oil and its derivatives): petroleum, gasoline and, in the case of aviation, kerosene.
Not exact matches
«Oil companies have processes to turn this [
syngas]
into gasoline, diesel fuel and jet fuel,» said Rich Masel, CEO of Dioxide Materials and a retired professor, pointing out how companies like BP PLC have operated synthetic fuel facilities for 20 years, albeit using natural gas instead of recycled carbon as a feedstock.
A fuel injector like those used in a car atomized the biofuels
into tiny droplets that landed on a hot rhodium - cerium catalyst, which converted the fuel to
syngas.
To boost efficiency, they are ditching the catalyst entirely and enlisting bacteria to ferment
syngas into ethanol.
«All of the
syngas goes
into heat or energy production,» Synfuels chemist Ed Peterson says, and the company cuts down on cost by using such by - products to make energy and employing components built with cheaper steel alloyed with carbon as well as easy to maintain low pressures.
It will focus on catalyst development for four applications: proton exchange membrane fuel cells to convert stored energy in non-fossil fuels
into electricity; electrolysers for splitting water
into oxygen and hydrogen — a potential clean fuel cell source;
syngas, a mixture of CO and H2, which is generated from coal, gas and biomass, and widely used as a key intermediate in the chemical industry; and lithium - air batteries.
«There was some interest in converting
syngas into ethanol during the first oil crisis back in the 70s,» said Ames Lab chemist and Chemical and Biological Science Program Director Victor Lin.
That converts most of the coal
into «
syngas,» which is mostly hydrogen and carbon compounds, and the rest
into ash.
Because CO2 is less concentrated and at much lower pressure in smokestack gases than it is in
syngas, it won't spontaneously dissolve
into a liquid solvent.
Unlike biomethane produced by anaerobic digestion, Bio-SNG is formed by the conversion of thermally - derived
syngas — i.e., via the gasification of biomass waste —
into methane.
So
syngas becomes more useful when separated
into hydrogen and carbon monoxide.
Once the researchers thermochemically split the water and carbon dioxide
into carbon monoxide and hydrogen (
syngas), they sent the
syngas to Shell Global Solutions in Amsterdam, where the Fischer - Tropsch process was applied to refine it
into kerosene, the jet fuel used by airplanes.
Traditionally
syngas was derived from natural gas or coal, but there has been much research
into solar fuels from the solar thermochemical splitting of water and carbon dioxide.
Researchers at the Department of Mechanical and Process Engineering at ETH Zurich, Switzerland, have concentrated 3,000 «suns» of solar thermal energy
into a solar reactor at 1,500 °C for thermochemical splitting of H2O and CO2
into hydrogen and carbon monoxide (
syngas), the precursor to kerosene and other liquid fuels.
The Rentech - SilvaGas biomass gasification process can convert multiple biomass feedstocks
into synthesis gas (
syngas) for production of renewable fuels and power.
The Rentech Process can also convert
syngas from fossil resources
into synthetic jet and diesel fuels, specialty waxes and chemicals.
This process involves converting coal
into a mixture of carbon monoxide and hydrogen called «
syngas.»
Nexterra Energy is commercializing its biomass gasification technology to generate power and heat from by direct - firing
syngas into high efficiency gas engines.
``... Integrated gasification combined cycle technology uses a coal gasification system to convert coal
into a synthesis gas (
syngas).
One of the engineers, Brett Wingo, who blew the whistle on schedule delays at the plant in a New York Times investigation earlier this month, noted that aside from the gasifier itself, which is supposed to turn lignite coal
into synthesis gas, or
syngas, there are numerous other first - of - its - kind systems that Southern is not publicly acknowledging as likely delaying factors in its bid to put its «clean coal» power plant — already two years behind schedule and almost $ 5 billion over-budget — on - line.
