Abstract

Microreactors consisting of channels etched into silicon are used to dehydrogenate cyclohexane to benzene. These reactors are fabricated by wet etching into silicon. The reactors contain a system of 10 channels 10 micrometers deep, 500 micrometers wide, and 50 mm long. The surface of the channels is sputtered with platinum to catalyze the gas-solid heterogeneous reaction. This endothermic reaction is heated and kept isothermal at 200 degree(s)C. The level of conversion is linked to the details of the geometry, pressure, and fluid flow regime. Experiments and simulations show that conversion is higher in the Knudsen regime due to a higher level of molecule-wall collisions.
