CO2 to Chemicals : An Overview
- 1. CO2 conversion to value added chemicals : An Overview Dr Vijaykumar S. Marakatti Research associate, JNCASR, Bangalore
- 2. CO2 level in earth atmosphere Global warming (Green house effect) caused by remarkable increase of CO2 emission into the atmospheres. Imbalance in carbon cycle. high blood pressure , headache , flushed skin and twitching the muscles , vomiting , irregular heartbeat
- 4. Contribution of CO2 emission by different countries
- 5. CO2 emission by different Sectors
- 6. 15,300 Mt CO2 in 203513,000 Mt CO2 in 2010
- 7. Source of CO2 The cost of CO2 separation varies in a wide range from 15 to 90 US$/t. The cost is today quite high being around 80−130 US$/tCO2.
- 10. Why CO2 activation is difficult
- 12. CO2 to methanol Hydrocarbon -----------------> CO +H2----------- > CH3OH Steam Reforming Fischer -Troph CO2 H2 If this process need to be viable – The price of CO2 and H2 should be less or equivalent to the Hydrocarbon price CO2-- > Flue Gas--- >Purification ,Seperation, sorption H2---> Renewable Energy sources --- > Electrolysis, water splitting, photo catalysis, wind. This process is highly exothermic, Heat need to be removed by water and 0.8 t CO2 /t MeOH is produced in this process
- 15. First Pilot Plat to Synthesize Methanol from CO2 and H2
- 17. Mitsui Chemicals has put a pilot plant capacity of 100 t/y MeOH at Osaka, Japan Petrochemical Factory
- 19. Production of H2 at Lower Cost
- 21. Why Methanol is so Important ? It is the raw material for various chemicals
- 22. Catalyst development for CO2 to Methanol Cu – H2 dissociation. ZnO2 with – dispersion of Cu and also absorption o f CO2
- 23. CO2 to methane Sabtier Reaction : CO2 + 4 H2--- > CH4 + 2H2O International Space Station (ISS) and other low orbit missions, metabolically-generated CO2 is removed from the cabin air and vented into space, resulting in a net loss of O2. This requires a continuous resupply of O2 via water electrolysis, large water difficult to store. CO2 + H2 ---- > Water + Methane O2 +H2 Respiration Astronaut Fuel
- 24. Norwegian company, Norway Flue Gas + Methane, Pilot Plant BP and thohaku University , Japan Highly selective for the Methane , H2 from Sea Water Desert Research institute Pilot plat – Conversion of Co2 to 60% at 300 C
- 25. CO2 to Dimethyl Ether CO2+H2 ----- > CH3OH ------- > DME CO2+H2--------------------------- > DME Bifunctionl catalyst -- Cu based catalyst to support on Acidic Zeolite ZSM-5 or Al2O3 oxide. Cu ---> CH3OH …. Zeolite helps in Dehydartaion High cetane number additive for the Fuel Diesel.
- 26. Korean Gas Corporation and Unitel technologies Worlds first Largest DME Plant From CO2 Capacity - 300 Kt /Y
- 29. Core Technology
- 33. Still a Lot Of Chemicals Need to Be Synthesized ………….Let Us Develop the catalyst and Process and Save the Earth From CO2……………….
- 34. Thank You
