| 英文摘要 | Electrochemical reduction of carbon dioxide to useful chemicalintermediates—Mainstream Engineering Corporation, 200 Yellow Place, Rockledge,FL 32955-5327Philip Cox, Principal Investigator, pcox@mainstream-engr.comMichael Rizzo, Business Official, mar@mainstream-engr.comAmount: $999,406.00 The rise of carbon dioxide (CO2)emissions from a range of power plants and industrial sources have contributedto alarmingly-increased atmospheric levels of CO2. Several capture and sequestration(CCS) technologies are under investigation to reduce CO2 emissions from newand existing coal- and gas-fired power plants and large industrialsources. Although there are a number of active and effective CCS programs, thereremains a strong need for alternative routes to recycle the CO2 into useful productsrather than just sequestering the CO2 for long-term storage. This will provide newvaluable products and drive a market for the CO2 to offset the capture costs. Thedirect use of the CO2 as a chemical feedstock represents a logical strategy.However, due to the high thermodynamic stability of CO2, conventional chemicalsynthesis routes require high activation temperatures and pressures to drivethe reaction, thus limiting the economic viability of the direct use of CO2. Electrochemicalactivation provides an alternative low temperature and pressure route with muchlower energypathway, thus facilitating direct reuse of CO2. Furthermore, the potentialsynthesis of carboxylic acids by the direct insertion of the electrochemicallyactivated CO2 radical represents a cost-effective pathway to an interesting andattractive class of chemicals. Carboxylic acids are used as key intermediatesin a wide range of pharmaceuticals, polymers, agrochemicals, and fragrances,with a large number of both high-volume and niche high-value products possible.In Phase I, Mainstream demonstrated the stable production of a range ofcarboxylic acid intermediates with high yields and current efficiencies usingMainstream’s high-performance gas diffusion based electrode structures and electrochemical flowcell design. The direct electrochemical insertion of CO2 not only provides apathway to utilizing abundant CO2 but offers an alternative more straightforwardand more environmentally acceptable route to many carboxylic acids. InPhase II, we will further optimize the gas diffusion electrode, electrochemicalcells design and overall reaction chemistry to maximize the yield, reaction rate andoverall energy efficiency for the capture and reuse of CO2. CommercialApplications and Other BenefitsMainstream’s electrochemicalsynthesis can be applied to utilize CO2 directly in a widerange of chemical syntheses of valuable organic intermediates. Ourapproach provides a low energy pathway to the utilization of the abundant supply of capturedCO2 providea market for the CO2 as well as providing an economically andenvironmentally viable approach to the production of in-demand chemicalintermediates. |
