CO2 is a naturally occurring gas in the atmosphere and is often released into the air as a result of burning fossil fuels. While some processes can burn CO2, such as the production of cement, other processes can use CO2 as a feedstock for certain reactions.
Using CO2 as a Feedstock
CO2 can be used as a feedstock for certain industrial processes, such as the production of methanol or formic acid. In these processes, CO2 is combined with hydrogen to create a new product. This process is known as "carbon capture and utilization" (CCU), as it captures CO2 from the atmosphere and utilizes it in a useful way.
Using CO2 in Combustion
CO2 can also be used in combustion reactions. When burning a fuel, the oxygen from the air combines with the fuel to create CO2 and water. This process is known as "carbon capture and storage" (CCS) because it captures the CO2 produced by the combustion process and stores it in the atmosphere.
Conclusion
CO2 can be used in both combustion and feedstock reactions. While combustion processes produce CO2 as a by-product, feedstock processes use CO2 as a feedstock to produce other products. Both processes are important in the effort to reduce carbon emissions and combat climate change.
