ABOUT e-CODUCT 

The EU-funded e-CODUCT project had a successful start in September 2022. The e-CODUCT tackles the environmental challenge of reducing greenhouse gas and acid gases caused by heating or industry. Existing technologies have no solution to the challenge of CO₂ conversion, which lies in the composition of streams containing other acid gases [e.g. H₂S], and the economic and environmental inefficiency of reactors. The e-CODUCT will address these challenges by electrifying a simultaneous chemical conversion of acid gas components [CO₂ and H₂S] into platform molecule CO and marketable S. The e-CODUCT will provide a new technology for two-step acid gas valorisation via i) conversion of CO₂ and H₂S into COS in a fixed bed reactor, and ii) COS conversion into CO and S using an electrothermal fluidised bed [ETFB] reactor:

The fluidised bed electrothermal reactor will produce industrially valuable carbon monoxide [CO] and sulphur [S] from carbon dioxide [CO₂] and hydrogen sulphide [H₂S]. The conversion process will involve two steps: the reduction of CO₂ and H₂S to carbonyl sulphide [COS] and the decomposition of COS into CO and sulphur. The e-CODUCT will optimise the reactor materials and catalysts and scale up to TRL6 to produce 16 t/year of CO while reducing the reactor size by 50%. The proposed technology is already used in methane cracking for hydrogen and carbon production and could be adapted for other applications such as fluid catalytic cracking, steam cracking and dehydrogenation.
