Abstract
A method for scale-up of a micro reactor process from lab to production scale comprises using a wall material for a lab reactor having thermal conductivity ≤3 W/m·K, and using a wall material for a production reactor having thermal conductivity ≥5 W/m·K. Desirably, flow velocity is kept constant, and the height of the production-scale process channel is determined by: wherein A B and C are constants; His the overall volumetric heat transfer coefficient, Dis the hydraulic diameter, λis the thermal conductivity of the wall, b is the empirically determined power to which the Reynolds number is raised in the equation for the Nusselt criteria (Nu=a·RePr) for the type of flow used, and h is the height of the channel, all in the production-scale process; and His the overall volumetric heat transfer coefficient in the lab-scale process.
