- 4. Reasons to avoid increase of c02 • Co2 is directly proportional to utilization of fossil fuels. • Co2 is one of the greenhouse gas which causes global warming. • Nature always has a power to balance everything but because of manmade disturbance there is a serious imbalance of co2. • In some conditions Co2 reacts with fog and forms a dangerous substance which can cause death of human being.
- 5. REVERSE COMBUSTION: • When ever we burn fossil fuels like petrol,diesel,coal etc, they release Co2 along with water, heat energy. This process is called combustion. CxHy + (x+y/4)O2 xCO2 + yH2O + Heat • Similarly what if this process is reversible Xco2 + yH2O + Heat CxHy + (x+y/4)O2 • This is called Reverse combustion.
- 6. Does Reverse combustion possible • The main difficulty while doing reverse combustion is providing high energy, providing that much high energy is a cost effective. • So by taking cost in to consideration it is decided that using renewable energy can be helpful. • One more difficulty is how we will capture CO2 from power plants. • However An amine based solution can absorb CO2 when flue gases from power plants are passed through it.
- 7. Procedure for Reverse combustion • Collecting co2 from power plants collecting • Using a catalyst bicarbonate solution undergoes a reaction in presence of water and heat. Reverse combustion • Hydro carbons nothing but fuel is obtained fuel
- 8. Merits & Demerits MERITS • Economical • Doesn't cause pollution • No noise DEMERITS • Sometimes Needs Reactor • Slow process • Requires large amount of energy
- 9. Conclusion: • The inputs of reverse combustion are much costlier so this process is economical. • The output of reverse combustion will be a fuel which on combustion gives out co2, we will reuse it so no excess co2 will be added to atmosphere thus we can control Global warming.
