Hand in hand with the flourish of the biodiesel industry, glycerol (GLY) as an inconvenient by-product hasgenerated environmental and sustainability concerns. Devising measures for efficient transformation ofGLY into value-added products is a promising solution. In this contribution, the transformation of GLYto lactic acid (LA) as a valuable chemical was investigated in a continuous process for industrial applications. In this regard, a catalytic method using heterogeneous Cu nanoparticles in NaOH solution was studiedin a microreactor by a CFD simulation. A seven-inlet micromixer comprising an optimized mixing unitwas incorporated for uniform distribution of the species. The effects of various parameters upon the processperformance were considered and the optimum points were determined. Also, the extent of theinfluence of each variable on LA yield was evaluated using sensitivity analysis techniques. While higherLA yield could be obtained at extreme scenarios, optimum values of the Re and temperature for obtainingthe maximum performance under sensible operating conditions were determined to be 0.108 and 510.1 Kwhich led to the optimum yields of 67.8% and 59.5%, respectively. Moreover, the sensitivity analysisrevealed that the molar ratio of OH /GLY and temperature were the most and least significant parameters,respectively.
