A PROCESS FOR PREPARING SUPPORTED TITANIZED CHROMIUM CATALYST AND A CHROMIUM CATALYST PREPARED THERBY

摘要

Process for preparing supported, titanized chromium catalysts, which comprises the following steps: A) bringing a support material into contact with a protic medium comprising a titanium compound and a chromium compound, B) optionally removing the solvent, C) optionally calcining the precatalyst obtained after step B) and D) optionally activating the precatalyst obtained after step B) or C) in an oxygen-containing atmosphere at from 400°C to 1100°C.
