What is Gasification?
Gasification is the thermal
conversion of carbonaceous feedstocks (biomass and coal)
into synthesis gas
(syngas - composed primarily of Hydrogen and Carbon Monoxide) using oxygen and
steam
to react with the solid fuel. Only inert ash/slag byproducts are
produced.
What feedstocks can be used?
Virtually any carbon-bearing
feedstock can be used including:
Coal & Biomass (i.e. renewable feedstocks -
agricultural residues, municipal solid waste, forest residues, etc.)
And various liquid feedstocks
How do you use synthesis gas?
This gaseous fuel can be used for a
number of clean energy applications including power generation,
liquid fuel
production (via catalysts), or Hydrogen production. Since gasification occurs in a reducing
(oxygen-starved) environment,
the product gas can be cleaned of its
contaminants prior to its combustion or conversion. And unlike combustion, gasification
can concentrate and sequester carbon
dioxide (CO2) to eliminate greenhouse gas emissions.
While biomass is inherently CO2
neutral, using gasification for coal with
CO2 sequestration
technologies represents a significant opportunity for long-term, safe utilization of coal
fuels.
Why use gasification
technology?
Gasification technology represents a
significant advancement and benefit over combustion or incineration technology
due to its innate ability to control
pollutants (i.e mercury from coal) and its ability to
produce multiple products
including: syngas, power, liquid fuels and
hydrogen vs. just steam from combustion.
Who
is recommending Gasification?
Gasification has recently received
significant recognition by a number of leading organizations including:
-
-
U.S. Environmental Protection
Agency, Office of Solid Waste
-
Natural Resources Defense Council
