Final answer:
Removing carbon content from coal before combustion is NOT a part of clean coal technology, as current technologies focus on capturing carbon after combustion, but do not typically involve the removal of carbon from coal before it is burned. (Option A)
Step-by-step explanation:
The question asks which option is NOT a part of the technology of clean coal. Clean coal technology mainly refers to various methods and technologies aimed at reducing the environmental impact of coal energy generation. These often involve steps such as:
Removing impurities from coal before combustion like sulfur.
Capturing and sequestering carbon emissions.
Converting coal to syngas for cleaner burning.
Injecting captured carbon dioxide into rock formations deep underground as a form of storage.
The correct answer to what is NOT a part of clean coal technology is A) Removing carbon content from coal before combustion, as current clean coal technology focuses on capturing carbon after combustion rather than removing it from the coal before burning. All the other options listed are part of clean coal strategies. Removing sulfur oxides from the emissions is also part of clean coal technologies to prevent issues such as acid rain.
