Abstract: A bed grading material includes fibers, a hardening agent, and a binder. The fibers include alumina, and the bed grading material may include a catalyst. The bed grading material can include a mixture of different fibers and can be vacuum formed, pressed, wet-laid, extruded, or 3D printed. The bed grading material may be beneficially incorporated into a reactor.
