Technology Outline (Process Description)

• The objective is to propose a one-pot CO2 capture and conversion to methanol at milder process conditions compared to the industrial methanol production from syngas by IITD:
• Rational design of a system of mixtures of polyamines and ionic liquids, having negligible volatility, will be able to absorb CO2 from industrial process streams.
• Detailed reaction kinetics and mechanism in such a reaction system will be first established in a lab scale batch slurry reactor and then lab scale continuous flow reactor.
• The possibility of extrapolating small diameter behavior to larger ones for a continuous integrated CO2 to methanol process in a scaled-up Slurry Bubble column reactor will be explored and investigated.
• The critical issues in such an extrapolation pertaining to mixing and hydrodynamic characteristics, establishing reliable similarity criteria that would result in similar mixing and hydrodynamics and hence transport and performance in two different scales will be attempted to be solved.
• Continuous high-throughput lab-scale slurry phase reactor investigations of the CO2 capture and methanol synthesis reaction for a long time-on-stream to assess the stability of the system before scale-up.
