Treatment of a water‐reactive powder

Abstract

The treatment of water-reactive solid waste chemicals which generate corrosive products poses unique problems of feeding and reactor design. These problems have been addressed on a bench-scale and the design of a unit suitable for hazardous waste has been developed. The water-reactive material used was powdered titanium trichloride which was reacted with water (and oxygen) to give titanium dioxide and hydrochloric acid. The acid was neutralized by an alkaline scrubbing media.

Enhancement of the photocatalytic activity of TiO2through spatial structuring and particle size control: from subnanometric to submillimetric length scale

“…The main problem of TiCl 3 is that it is an explosive and pyrophoric compound, while both TiCl 3 and TiCl 4 form highly corrosive HCl vapors upon hydrolysis. [79][80][81] These harsh acid conditions can damage to some extent the zeolite structure particularly producing a partial loss in crystallinity.…”
