本文提出一个基于生物质气化的甲醇-动力多联产系统.该系统突出特色在于取消了变换过程,取消重整过程,并且适度循环未反应合成气,通过耦合化工与动力过程实现化学能的组分对口、分级转化以及物理能梯级利用原则.通过对系统分析炯结果表明,该系统与分产系统(独立甲醇生产系统,生物质气化联合循环)相比,节能高达10个百分点,该系统为生物质未来应用提供一个新的途径. In this paper, a methanol-to-power polygeneration system based on biomass gasification is proposed, which features prominent features such as abolishing the transformation process, eliminating the reforming process, and moderately recycle unreacted syngas to achieve chemical energy through coupling of chemical and kinetic processes Component alignment, graded transformation and physical cascade utilization principle.By analyzing the results of system analysis, it shows that the system saves energy by up to 10 percentage points compared with that of the separation system (independent methanol production system and biomass gasification combined cycle) The system provides a new way for the future application of biomass.
