We have developed an end-to-end catalytic process for the reduction of co2 to value-added chemicals like methanol (ch3oh), carbon monoxide (co), dimethyl ether (dme) and methane (ch4). ch3oh and dme are potential future fuels having high octane and cetane numbers and can also form the basis of many chemical industries. co on the other hand is presumed to be one of the most consumed chemicals in the world having tremendous applications in metal fabrication, chemical & steel industry, pharma and electronic industry. the overall process can be divided into 5 sub-technologies viz. (a) co2 capture, (b) hydrogen production, (c) catalyst design, (d) reactor design and (e) purification technologies. the carbon capture technology used by us is an amine-based process where 90.7% co2 is recovered from any industrial flue stream with a dry weight purity of 99.5% at a cost lesser than the commercial co2 price. the hydrogen to be used as the reductant is proposed to be obtained from electrolysis of alkaline water or from biomass. catalyst synthesis is at the core of this overall technology. the catalysts have been synthesized through extensive structure-property relation study corroborating with 1st principle dft calculations. advanced cfd calculations have been used to design reactor systems with high energy, water and conversion efficiency. nano structuring of the group 13 element doped czz systems showed highly enhanced conversion and methanol selectivity. the metal oxide based composite catalyst was synthesized in a powder form with different compositions and different synthesis conditions through ph sensitive solution phase techniques. we have developed an innovative ph, conductivity and temperature controlled system for large-scale synthesis of the catalyst. our developed class of heterogeneous catalysts performs co2 reduction at 250 °c-300 °c with ghsv = 3600 /h in continues down-flow reactor at the operating pressure from 20- 50 bar. the feed ratio of gases are h2 and co2 = 3:1. with the major products as meoh and co we have been able to achieve conversion in the range of 40-45% in single pass with ~ 45 % meoh selectivity. introduction of recycling of gases has led to about 2-3 fold increase in the overall conversion. as the process is continuous it operates at steady state once the equilibrium is achieved which takes initial 3 hrs. of reaction. once the equilibrium and reaction conditions are achieved, no regular warm or cool down cycles are required during the operation conditions. our catalyst systems have shown high stability of more than 72 hours continuous tests and studies for month long catalytic test are currently undergoing. the purification of the product is another aspect, which can be a game changer in the commercialization process of the integrated technology. while liquid product purification is a comparatively trivial process, we have designed psa (pressure swing adsorption) and cryogenic cooling based energy and cost effective purification techniques for separation of gaseous products like co2, co, h2 and ch4. we have tied up with companies like tata power, thermax, greenvision technologies, novomer, carbon clean solutions to help us in parts to develop the technology to the commercial scale. we are in the process of taking our technology to the pilot plant scale during the course of which we are running as semifinalists in the 20 million-dollar nrg carbon cosia xprize, which is a global competition for promoting novel technologies for solving co2 and climate change issues. our technological initiative has also been selected among the top 100 startups in the elevate 100 program of the govt. of karnataka.
