The concentric configured thermally-coupled double-membrane reactor (TCDMR) was optimised to improve the co-production of hydrogen and methanol. Using a detailed approach, we identified the non-linear differential evolution (DE) algorithm as the most suitable optimisation tool among the most used optimisation algorithms in reactor design (GA, PSO, and DE) due to its ability to converge to the optimal solution with fewer iterations. Considering DE algorithm with the industry benchmark data, we optimised the key operational parameters of TCDMR (as OTCDMR), leading to the improved reactor performance (regarding the overall heat transfer and methanol/hydrogen production) compared to the conventional methanol reactor (CMR) and TCDMR. Simulation results show that the methanol production rate of OTCDMR could reach 315.7 tonnes day⁻¹, representing a 22.6% enhancement than CMR (257 tonnes day⁻¹). For the hydrogen production, OTCDMR is predicted to deliver 19.7 tonnes of hydrogen per day, surpassing the 15.5 tonnes day⁻¹ production rate by TCDMR.

对同心配置的热耦合双膜反应器（TCDMR）进行了优化，以提高氢气和甲醇的联产。使用详细的方法，我们将非线性微分进化（DE）算法确定为反应堆设计中最常用的优化算法（GA，PSO和DE）中最合适的优化工具，因为它具有收敛到最优解的能力迭代次数更少。考虑到具有行业基准数据的DE算法，我们优化了TCDMR（作为OTCDMR）的关键运行参数，与传统的甲醇反应器（CMR）和TCDMR。模拟结果表明，OTCDMR的甲醇日产量可达到315.7吨^-1，比CMR（257吨日^-1）提高22.6％。对于氢气生产，预计OTCDMR每天将提供19.7吨氢气，超过TCDMR每天的15.5吨^-1生产率。
