Abstract This work proposed a pyrolysis chemical looping reforming‐two stage regeneration (PCLR‐TR) process with carbon‐negative syngas and biochar poly‐generation，aimed at overcoming challenges in gasification. The effectively separates reforming, circumventing slow solid–solid reactions enabling the flexible adjustment of H 2 /CO ratio. two‐stage ensures improved synchronization reaction rates across different reactors. results indicate that manipulation parameters allows for ratio (ranging from 1.02 to 3.83). introduction CO feed first reactor reduces oxygen carrier exothermic intensity second by 58%. Optimization suggest generated is compatible diverse downstream applications, exhibiting maximum negative emission 1.85 kg/kg syngas. PCLR‐TR system offers versatile environmentally friendly solution energy industries.
