With a total of 2 patents to his name, Malcharek's work has advanced the methods used in the production of this important compound.

Latest Patents

Malcharek's latest patents include a method for manufacturing titanium dioxide by oxidizing titanium tetrachloride. This innovative method involves reacting titanium tetrachloride with an oxygen-bearing gas in a tubular reactor. The process includes cooling the titanium dioxide particle/gas mixture in a cooling section, where the gas/particle flow is caused to rotate. The introduction of titanium tetrachloride in the cross-sectional plane of the reactor, rather than in the radial direction, allows for a flow velocity of the oxygen-bearing gas exceeding 20 m/s. This design helps scrub solids free from the reactor's inner wall, enhancing cooling performance and producing a titanium dioxide pigment with a narrow particle size distribution.

Another significant patent by Malcharek is a method for separating titanium tetrachloride. This invention addresses the separation of titanium tetrachloride and its hydrolyzed reaction products from exhaust gases generated during the chlorination of titanium-containing raw materials. The method employs a first aqueous hydrochloric-acid solution of titanium oxychloride to treat the exhaust gases, ensuring efficient separation with minimal pressure loss in the scrubber system.
