Abstract
A gas mixer and distributor for a reactor has first and second inlet chambers with the second inlet chamber being interposed between the first inlet chamber and an entrance to a reaction chamber. Walls form tubular or slit-like passageways extending from the first chamber to the entrance of the reaction chamber through the second chamber. Upper portions of the passageways have uniform cross-sections selected to produce gas velocities above the flashback velocity, as well as producing turbulence to completely mix gas passing from the second chamber through orifices in the walls of the passageways. Lower sections of the passageways gradually increase in cross-section to reduce velocity and minimize vortexing and recirculation at the entrance to the reactor chamber.
