FIELD: chemical technology. SUBSTANCE: carrier is made by mixing of titanium oxide and water in the presence of peptidizing agent - alkanolamine, ammonia or ammonia-evolving compound. Total content of solid phase is 50-70% , concentration of peptidizing agent is 2-5% of total content of solid phase. Then prepared mixture is stirred and formed by extrusion. Monoethanolamine is used as a alkanolamine. Mixing can be carried out by silica or zeolite U addition. Shaped carrier is dried and calcined. Carrier properties: carrier shows enhanced strength 0,25-0,90 MPa ( by crushing in the volume ). EFFECT: improved method of carrier making.
