Are China's new nuclear Reactors using pebble- bed technology?
I have the feeling that they are not??


Here is one GW problem solved before I knew it was a problem!

An Environmentally Friendly Approach To Ethylene
Submitted by News Account on 5 February 2008 - 12:36pm. Chemistry

Ethylene, the world's most commonly produced organic compound
, is used many types of industries. Farmers and horticulturalists use it as a plant hormone to promote flowering and ripening, especially in bananas while doctors and surgeons have long used ethylene as an anesthetic and ethylene-based polymers are found in everything from freezer bags to fiberglass.

Its current production methods result in a number of greenhouse gases.
A new environmentally friendly technology created by scientists at Argonne National Laboratory may revolutionize creation of this compound by use of a high-temperature membrane that can produce ethylene from an ethane stream by removing pure hydrogen.

Says senior ceramist Balu Balachandran, “This is a clean, energy-efficient way of producing a chemical that before required methods that were expensive and wasteful and also emitted a great deal of pollution.”

Because the new membrane lets only hydrogen pass through it, the ethane stream does not come into contact with atmospheric oxygen and nitrogen, preventing the creation of a miasma of greenhouse gases – nitrogen oxide, carbon dioxide and carbon monoxide – associated with the traditional production of ethylene by pyrolysis, in which ethane is exposed to jets of hot steam.
The world’s ethylene producers manufacture more than 75 million metric tons of ethylene per year, causing millions of metric tons’ worth of greenhouse gas emissions.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
