Abstract
The lifetime of a fluidized bed reactor containing silicon particles, for the production of chlorosilanes is greatly extended by armoring at least a portion of the reactor shell interior wall with expanded metal coated with a cement containing ceramic particles.
Claims16
A fluidized bed reactor for preparing chlorosilanes, comprising a metal reactor shell, wherein an inner wall of the reactor shell has expanded metal attached thereto, and the expanded metal is coated with a cement comprising ceramic particles, wherein the ceramic particles comprise silicon carbide, silicon nitride, boron nitride, zirconium oxide, aluminium nitride, or mixtures thereof.
A process for applying abrasion protection to a steel surface of a fluidized bed reactor, comprising attaching an expanded metal onto the steel surface, mixing cement comprising ceramic particles with water to produce a suspension, applying the mixed cement to the expanded metal and drying and curing the cement, wherein the ceramic particles comprise one or more of silicon carbide, silicon nitride, boron nitride, zirconium oxide and aluminium nitride.
