Abstract
In the proposed reaction process, at least two educts (A, B) are divided by their respective assemblies of microchannels (1a, 1b) into spatially separated fluid filaments. These fluid filaments then enter a common mixing and reaction chamber (4). It is essential that the fluid filaments of the two educts (A, B) are allowed to enter the mixing/reaction chamber (4) as free jets (6a, 6b), each free jet (6a) of an educt (A) being led into the mixing/reaction chamber (4) immediately adjacent to a free jet (6b) of a different educt (B). Adjacent free jets then mix by diffusion and/or turbulence. This system significantly accelerates the mixing process by comparison with conventional reactors, and, with rapid chemical reactions, largely prevents the formation of unwanted by-products and secondary products.
