Abstract

Various wear resistance designs may be applied to a reactor configured to facilitate chemical reactions, and / or comminution using shockwaves created in a supersonic gaseous vortex. The reactor may include a rigid chamber having a substantially circular cross-section. A first gas inlet may be configured to introduce a high-velocity gas stream into the chamber. A first replaceable wear part may be disposed in the chamber to absorb wear impact caused by the gas stream. In some implementations, the first replaceable wear part may be a cylindrical rod continuously fed into the chamber. In some implementations, the first replaceable wear part may be coated with, or composed of, a catalytic material, and / or may be electrically isolated from the rest of the reactor. In some implementations, a second gas inlet may be disposed to steer the gas stream to a desired area within the chamber to even out the wear impact.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application Serial No. 14 / 690,111 filed April 17, 2015, which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to providing attrition resistance in reactors configured to utilize shock waves generated in supersonic gas vortices to facilitate chemical reactions and / or comminution of solid feedstocks. Background technique [0004] It is known in the art to comminute solid feedstock in a milling chamber using a gas flow. For example, a jet mill is a grinding device that relies on a high-velocity gas stream to grind material within a grinding chamber. Comminution may take place in the jet mill's central annular grinding chamber because the process material is driven around the perimeter of the jet mill's central annular grinding chamber by a porous jet of air or steam. Size reduction by friction may be due to high...
