Whole kernel shelled Corn is the low cost energy - Not Corn Ethanol
- Ken, Corn ethanol is a governmental sponsored tax waste project. We all
know first hand on this forum that energy savings is in whole kernel
shelled corn purchased directly from the local corn farm. Purchase a
corn stove directly from a local corn stove dealer. Pellet stoves do
not safely run on 100% corn but corn stoves will run on pellets with
somewhat reduced safety. Non-corn fuels hazardously burn in an enclosed
hopper. Corn does not.

Environmental News Network, Wednesday, September 05, 2001, Located on
a peninsula next to Lake Erie, this Niagara Mohawk coal-fired station
produces 600,000 kilowatts of 60-cycle power along with emissions
containing mercury. corn may be the key. Illinois scientists are
pleased with a successful full-scale test of a substance derived from
corn in a demonstration of the process that took place July 30 through
Aug. 12 at the University of Illinois Abbott Power Plant. The
carbon-injection demonstration compared the performance of a
commercial activated carbon with that of a corn-derived activated
carbon developed by researchers at the Illinois State Geological
Survey (ISGS) and the University of Illinois at Urbana-Champaign.
"This full-scale test capped a five-year collaborative effort to
develop low-cost adsorbents for the removal of mercury," said Massoud
Rostam-Abadi, a chemical engineer and the head of energy and
environmental engineering for the Illinois State Geological Survey.
"The test also marked the first time the carbon-injection technology
was applied to high-sulfur Illinois coal flue gas." Mercury is a
toxic pollutant that can enter rivers, lakes, and the human food
chain. Coal-fired power plants are one of the largest human-generated
sources of mercury emissions. Rostam-Abadi and his team have been
working for years to come up with low-cost, highly effective materials
to remove mercury from combustion flue gases. Old tires and pistachio
shells looked promising, but they were eclipsed by the potential of
corn. "Earlier this year we worked with engineers from URS Radian in
Austin, Texas, to look at the effectiveness of corn-based activated
carbons for removing both elemental mercury and mercuric chloride from
simulated coal combustion flue gases," Rostam-Abadi said. Initial
tests indicated that activated carbon adsorbents made from corn could
work as well as or better than current commercial products and might
even be cheaper to produce. Then in May the researchers screened 13
of their experimental adsorbents using actual flue gas from the Abbott
Power Plant. Based on the results of those bench-scale tests, two
activated carbons a corn-based material and a commercial product
were selected for full-scale testing. "In the carbon-injection
process, adsorbent particles are typically in contact with the flue
gas for less than a few seconds," said Mark Rood, a University of
Illinois professor of civil and environmental engineering. "Therefore,
the most desirable adsorbent would have high reactivity and low cost."
A team of engineers from Apogee Scientific in Denver and URS Radian
worked with ISGS and University of Illinois engineers to conduct the
full-scale tests at Abbott Power Plant, a 30-megawatt facility that
burns high-sulfur Illinois coal. First, parametric testing and
optimization were performed with the commercial carbon. Those results
were then compared with results obtained with the corn-derived carbon.
"One of the unique aspects of our program is going from laboratory
development to pilot-scale testing and then to full-scale testing,"
Rostam-Abadi said. "Few universities have that capability."
Collaborators on the project included ISGS chemical engineer Scott
Chen and UI graduate students Hsing-Cheng Hsi and Christopher Lehmann.
Electric Power Research Institute, Illinois Clean Coal Institute,
Illinois Office of Solid Waste Research, and Illinois Corn Marketing
Board supported the research financially. Mercury is No. 3 on the
federal government's list of the Top 20 hazardous substances, issued
by the U.S. EPA and the Agency for Toxic Substances and Disease
Registry. The nervous system is very sensitive to all forms of
mercury. The EPA has determined that mercuric chloride and methyl
mercury are possible human carcinogens. Methyl mercury and metallic
mercury vapors are more harmful than other forms because more mercury
in these forms reaches the brain. Exposure to high levels of metallic,
inorganic, or organic mercury can permanently damage the brain,
kidneys, and developing fetus. Effects on brain functioning may result
in irritability, shyness, tremors, changes in vision or hearing, and
memory problems. Short-term exposure to high levels of metallic
mercury vapors may cause effects including lung damage, nausea,
vomiting, diarrhea, increases in blood pressure or heart rate, skin
rashes, and eye irritation. In 1995 pilot tests by the German power
company STEAG, the ISGS char captured 99.7 percent of the cancer
causing dioxins and furans emitted by the incineration process. The
char took up 90 percent of the cadmium and titanium and 50 to 75
percent of the antimony, arsenic, lead, chromium, cobalt, copper,
manganese, nickel, vanadium, and tin. Mercury was no longer detectable
in the flue gas.
