co2 dioxyde carbon carbon dioxide fuels science

shared by Jac Londe on 18 Jun 12 - No Cached

Today, carbon dioxide (CO2) is a hot topic. Scientists around the globe are searching for ways to store, dispose of, or prevent the formation of the greenhouse gas, which is a major driver of global climate change. Liquid Light hopes to take this concept one step further and harness waste CO2 as a source of carbon to make industrial chemicals and fuels.

Take CO2 and mix it in a water-filled chamber with an electrode and a catalyst. The ensuing chemical reaction converts CO2 into a new molecule, methanol, which can be used as a fuel, an industrial solvent or a starting material for the manufacture of other chemicals.

Bocarsly likes to call the process "reverse combustion" because it is like running a burning reaction backwards. Instead of burning fuel and oxygen to produce CO2, the CO2 converts back into fuel and oxygen.

Cole set up a flask containing a solution of CO2 and a pyridinium catalyst dissolved in water. In place of sunlight, which emits a broad spectrum of wavelengths of light, she shined on the flask a blue light-emitting diode (LED) because it gives off certain wavelengths that are highly efficient at driving the reaction. In the flask she placed an electrode that is activated by particles of light, or photons. "We used a semiconductor electrode that would allow us to substitute light for electricity," said Cole.

The Princeton scientists did some additional studies, and made a surprising discovery: They could turn CO2, which contains only one carbon, into a compound with a carbon-carbon bond, which vastly increases the possibilities for creating commercial applications.

How much CO2 is created by a banana? A wedding? A flight to New York? We teamed up with GE to turn 'tons of carbon' into an interactive visual landscape. Enter a CO2 value. Hit the 'random' button for serendipity. Or just click through objects like stepping stones. (There are nearly 200 objects so it may take a second to load) Designed by David McCandless

Great activity to help students use NASA data in order to develop a community-based strategy to reduce greenhouse gas emission. Includes additional resources (articles, websites, NASA instruments) to help students learn about CO2 emissions, what is being done around the world, to decrease CO2 emissions, and what they can do.

Utilization doesn't just take into account the 20 percent of recycled plastic. But it also considers the incinerated 52 percent used for energy recovery like generating electric power or heat. Akinori Ito says "If we burn the plastic, we generate toxins and a large amount of CO2. If we convert it into oil, we prohibit CO2 production and at the same time, increase people's awareness about the value of plastic garbage"

Oil from Shale: Oil can be extracted from this fine grained, organic rich, sedimentary rock through pyrolysis, thermal dissolution or hyderogentation. Shale contains high concentrations of organic chemical compounds known as Kerogen. From this solid mixture, oil is extracted through chemical process. Shale can be effective converted into combustible oil shale gas and liquid hydrocarbons (shale oil). Global deposits of Shale are estimated to be around 2.8 trillion to 3.3 trillion barrels of restorable oil. Planet earth is blessed with about 600 known oil shale deposits, most of which is found in United States of America. Although several countries have oil hale deposits, known deposits of economic importance is found only in 33 countries.

The data we're including in this first launch represents just a small fraction of all the interesting public data available on the web. There are statistics for prices of cookies, CO2 emissions, asthma frequency, high school graduation rates, bakers' salaries, number of wildfires, and the list goes on. Reliable information about these kinds of things exists thanks to the hard work of data collectors gathering countless survey forms, and of careful statisticians estimating meaningful indicators that make hidden patterns of the world visible to the eye. All the data we've used in this first launch are produced and published by the U.S. Bureau of Labor Statistics and the U.S. Census Bureau's Population Division. They did the hard work! We just made the data a bit easier to find and use.
