SYSTEM AND METHOD OF CATALYST ACTIVATION Russian patent published in 2014 - IPC B01J37/08 B01J37/12 B01J38/12 B01J38/20 B01J23/26 C08F10/00 C08F4/24 

FIELD: chemistry.

SUBSTANCE: described are methods of chrome catalyst activation, which include increasing chrome catalyst temperature in, at least, bilinear changing, which contains increase of chrome catalyst temperature at first speed during first period of time to first temperature on first site of changing of bilinear changing; and increase of chrome catalyst temperature at second speed during second period of time from said first temperature to second temperature on second site of changing of bilinear changing, which follows directly after first area of changing, and first speed is larger, than second speed, and first period precedes second period; with first temperature being in the range from approximately 650°C to approximately 750°C, with second temperature being in the range from approximately 750°C to approximately 850°C. Method of obtaining polyolefines in presence of catalyst, activated by claimed method, is described.

EFFECT: increased efficiency of catalyst activation.
