This work presents the modeling and thermodynamic analysis of two novel small-scale polygeneration systems that are capable of simultaneously converting residual biomass to methanol (MeOH), electricity, heat and a CO₂-rich stream for agricultural greenhouses. The first system is based on a downdraft gasifier, while the second relies on a dual fluidized bed (DFB) gasifier. Both configurations leverage the H₂, O₂, and electricity generation capabilities of reversible solid oxide cells (RSOCs). The Aspen Plus process simulator is used to model the thermodynamic performance of the proposed polygeneration systems, which operate at total efficiencies ranging from 83.9 to 85.0%. From a biofuel and electrical efficiency perspective, the system based on a DFB gasifier is superior, providing the added benefit of enabling carbon capture and storage, as a N₂-free stream with a molar purity exceeding 90% CO₂ is generated, which could be readily liquefied or sequestered.

这项工作介绍了两种新型小规模多联产系统的建模和热力学分析，这些系统能够同时将残余生物质转化为甲醇 (MeOH)、电力、热能和农业温室富含CO _{2 的}流。第一个系统基于下吸式气化器，而第二个系统依赖于双流化床 (DFB) 气化器。两种配置均利用 H ₂、O ₂以及可逆固体氧化物电池 (RSOC) 的发电能力。Aspen Plus 过程模拟器用于模拟所提议的多联产系统的热力学性能，该系统以 83.9% 至 85.0% 的总效率运行。从生物燃料和电力效率的角度来看，基于 DFB 气化器的系统是优越的，提供了实现碳捕获和存储的额外好处，因为生成摩尔纯度超过 90% CO ₂的无 N ₂流，这可以易于液化或隔离。
