Startup Reduciner Oy has developed an electrified thermochemical process that converts captured CO2 and biochar into carbon monoxide (CO)-rich syngas and activated carbon, improving the economics of CO2 utilization by producing valuable co-products. The system uses the Reverse Boudouard reaction in a proprietary, electrically heated rotary-kiln-like reactor, achieving over 90% CO2-to-CO conversion in trials; the activated carbon co-product targets applications such as water treatment, metals recovery, and air purification.

What industries or sites (e.g., steel plants, chemical hubs, water utilities) are best positioned to integrate this reactor, considering access to CO2 streams, biochar supply, and low-cost electricity?

Electrified process converts CO2 and biochar into industrial products

The production of salable co-products can substantially improve the economics for CO2 conversion processes. A new electrified thermochemical process developed by startup Reduciner Oy combines captured CO2 streams with biochar to produce carbon monoxide, along with activated carbon, a valuable material in water treatment, metals recovery, air purification and many other applications. Powered by the Reverse Boudouard reaction converting CO2 to CO-rich syngas, the cornerstone of Reduciner’s technology is a proprietary reactor that behaves similarly to an electrically heated rotary kiln, where CO2-to-CO conversion efficiency has climbed above 90% in trial operations.

Reverse Boudouard will swing hard when char reactivity, CO2 flow, or power drifts; how are you holding temp and residence time to get >90% without over-gasifying the activated carbon? What ash/volatile specs do you put on the biochar, and how do you keep fines from shredding seals or loading the CO line? Please tell me you interlock for O2 ingress and power dips, because one puff of air in a hot kiln is a bad day.

Reverse Boudouard at >90% is impressive, but what is the specific power draw (kWh per Nm3 of CO) and how clean does the CO2 stream need to be with respect to O2 and H2O? In rotary environments we fight alkali-driven ring formation and sintering from biochar ash, are you seeing agglomeration or high attrition rates that impact activated carbon quality and particle size distribution?
