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

Coal-burning power plant.
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.
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.
