Updating content from the author’s 2001 book
Coal Desulfurization
, this new title focuses on CO
2
sequestration and utilization. It includes information on the theory and practical approaches to CO
capture and recent advances in the use of sequestered CO
.
Avoiding these pollutants requires either forgetting about the 250 billion tons of coal reserves the United States possesses or capturing and utilizing the pollutants in a profitable and environmentally responsible fashion. The book covers postcombustion and precombustion capture approaches for coal, and postcombustion capture can be generalized to many other fuels. Recent practical implementations at full-scale power facilities around the world are discussed. The book covers sequestering CO
via underground, oceanic, biological, and other long-term CO
storage methods. It also includes recent advances in utilizing CO
for enhanced oil recovery, advances in storage with depleted oil and gas reservoirs and deep saline aquifers, and additional topics.
The book also examines specific applications of pure CO
and covers chemical conversion of CO
to useful compounds. It answers questions like "Can we create methanol from coal?" or "Can we create ethanol from coal?" It is found that methanol and ethanol cannot be sustainably produced from coal power alone. However, oxalic acid can be created at a much lower energy cost than methanol or ethanol. Oxalic acid can be used to extract rare earths, which are not currently produced anywhere in the United States, but are typically concentrated in coal ash.
Aimed at researchers and industry professionals in chemical, environmental, and energy engineering, this book provides insight and inspiration into capturing CO
not merely as a response to regulatory pressure and climate change but as an inherently profitable and valuable venture.
