“…The fuel reactor houses the highly endothermic reaction, and heat is furnished by the air reactor's high‐temperature oxygen carrier and heat carrier (SBA‐15). Previous studies have demonstrated that the oxygen carriers embedded into SBA‐15 exhibit enhanced reactivity and improved cycling stability 38,44 . After heat recovery and purification, the syngas product stream is obtained.…”

This article introduces a pyrolysis chemical looping reforming (PCLR) process that produces carbon‐negative syngas in autothermal operation. To enhance the system's carbon negativity, a process configuration with oxygen carrier two‐stage regeneration is adopted, enabling internal CO2 utilization. The PCLR process is systematically evaluated and compared to chemical looping gasification and steam gasification processes in the process performance, energy efficiency, and environmental impact using a process model. Results reveal significant improvements over chemical looping gasification, including 69%, 45%, and 4% improvement in syngas yield, energy efficiency, and environmental benefit. Process analysis demonstrates that decoupling volatile reforming from pyrolysis and combustion enhances syngas quality, energy efficiency, and process flexibility. While the two‐stage regeneration sacrifices syngas production, it contributes to a 4% increase in carbon negativity and a 15% reduction in carbon emissions. Thus, the PCLR process effectively overcomes the limitations of chemical looping gasification systems and exhibits excellent process intensification performance.

The catalytic cracking of pyrolysis gasification tar into H2 has garnered significant attention due to its exceptional conversion efficiency. In this study, the effects of pollutant concentration, residence time, weight hourly space velocity (WHSV), and reaction temperature on the hydrogen performance of LaFe0.5Ni0.5O3 perovskite were comprehensively investigated. Results revealed that moderate pollutant concentration (0.3 g/L), low-medium residence time (250 SCCM), and low WHSV (0.24 gtoluene/(gcat·h)) facilitated efficient interaction between LaFe0.5Ni0.5O3 and toluene, thus achieving high hydrogen production. An increase in reaction temperature had minimal effect on the hourly hydrogen production above 700 °C but caused a significant increase in methane production. Additionally, the effects of oxygen evolution reactions, methane reactions, and methane catalytic cracking reactions of perovskite induced by different reaction conditions on tar cracking products were discussed in detail. Compared to previous reports, the biggest advantages of this system were that the hydrogen production per gram of tar was as high as 1.002 L/g, and the highest hydrogen content in gas-phase products reached 93.5%, which can maintain for approximately 6 h. Finally, LaFe0.5Ni0.5O3 showed good thermal stability, long-term stability, and catalyst reactivation potential.
