Pulsed flow reactor and use thereof

A flow reactor comprising:

• a straight planar process channel having a longitudinal direction and being delimited by a bottom wall, a top wall, two side walls, a first end wall, and a second end wall opposite to said first end wall along said longitudinal direction, the process channel comprising at least one inlet at said first end wall configured to introduce at least one feed stream into said process channel and at least one outlet at said second end wall configured to discharge at least one product stream from said process channel;
• a flow generator configured to generate a pulsatile flow within said process channel, the pulsatile flow comprising a unidirectional net flow component through said process channel along said longitudinal direction and an oscillatory flow component superposed on said net flow component;
• and
• a plurality of static mixing elements disposed within said process channel and configured to locally split and recombine the pulsatile flow, wherein said mixing elements fill up at least 5% of said internal volume and at most 30% of said internal volume.
