Simple, Low-cost Carbon Filter Removes 90 Percent Of Carbon Dioxide From Smokestack Gases

ScienceDaily (May 20, 2008)
— Researchers in Wyoming report development of a low-cost carbon filter
that can remove 90 percent of carbon dioxide gas from the smokestacks
of electric power plants that burn coal and other fossil fuels.


Coal-burning power plant.

Maciej Radosz and colleagues at Wyoming's Soft Materials Laboratory
cite the pressing need for simple, inexpensive new technologies to
remove carbon dioxide from smokestack gases. Coal-burning electric
power plants are major sources of the greenhouse gas, and control
measures may be required in the future.
The study describes a new carbon dioxide-capture process, called a
Carbon Filter Process, designed to meet the need. It uses a simple,
low-cost filter filled with porous carbonaceous sorbent that works at
low pressures. Modeling data and laboratory tests suggest that the
device works better than existing technologies at a fraction of their
cost.
