METHOD OF A CATALYST CARRIER MATERIAL PRODUCTION OF AND A METHOD OF PRODUCTION OF THE CATALYST Russian patent published in 2005 - IPC

FIELD: chemical industry; production of a catalyst carrier material and the catalyst.

SUBSTANCE: the invention is dealt with the field of chemical industry. The method of production of a catalyst carrier material includes the following stages: (a) treatment of the utilized catalyst of titanium dioxide-on-silicon dioxide to clear from coke; (Ь) washing of the catalyst cleared from the coke by a flushing fluid chosen from a water solution of an inorganic acid, a water solution of an ammonium salt and their combinations; (c) drying and calcination of the catalyst washed out and cleared from the coke with production of the catalyst carrier material. The technical effect - the material produced this way is fit for use as the carrying agent material for titanium dioxide in a heterogeneous catalyst for epoxidation of olefines in alkylene oxide.

EFFECT: the invention ensures production of the material fit for use as the carrying agent material for titanium dioxide in a heterogeneous catalyst for epoxidation of olefines in alkylene oxide.
