Patent ID: 10399034

Abstract:
The high temperature titanium-catalyst comprises a body, the body having a hot gas inlet and a hot gas outlet. The body comprises an array of titanium containing catalytic elements, wherein the array of titanium containing catalytic elements is arranged such that hot gas containing an amount of hexavalent chromium Cr(VI) may enter the body at the hot gas inlet, may pass through the array of titanium containing catalytic elements and may leave the body at the hot gas outlet. When the titanium-catalyst is in use, Cr(VI) in the hot gas containing an amount of Cr(VI) reacts with titanium oxide in a surface layer of the titanium containing catalytic elements, whereby the Cr(VI) is reduced to trivalent chromium Cr(III) thus reducing the amount of Cr(VI) in the hot gas containing an amount of Cr(VI).
