Feasibility Study of CO₂ Control in Automobile Sources

In the recent years, due to the rapid escalation in the vehicle population and deforestation, the CO₂ level in the atmospheric has been increased drastically. Since CO₂ is formed due to complete combustion of fuel, which is desirable for getting more millage, the abnormally increased CO₂ level causes climate change problems. To mitigate the CO₂ level in the atmosphere, different approaches like absorption, adsorption and membrane separation can be adopted in the automobile sector. This chapter provides the information about the CO₂ emissions worldwide and nationwide. The experimental results show that the phase change fluids like amine solutions have better absorption characteristics up to 90%, as compared with activated carbon and zeolites. The regeneration of amines after absorption is, however, a big challenge, especially when it is used in vehicles. Possible technologies to alleviate the CO₂ emission from the automotive sector are also discussed.
