METHOD OF DETERMINING POLYMERIZING ACTIVITY OF UNSATURATED COMPOUND HYDROGENATION CATALYSTS Russian patent published in 2007 - IPC G01N21/17 G01J3/51 B01J23/88 B01J23/44 B01J23/755 C10G45/00 

FIELD: petrochemical process catalysts.

SUBSTANCE: invention relates to determining polymerizing activity of catalysts that can be used for hydrogenation of unsaturated compounds contained in liquid pyrolysis products. As a variable reflecting polymerizing activity of hydrogenation catalysts, optical density value of liquid mixture is used, said mixture containing unsaturated compounds and being kept in contact with catalyst at elevated temperature for a predetermined period of time. Determination of polymerizing activity is accomplished by comparing optical density of liquid mixture containing unsaturated compounds before and after its contact with catalyst. In order to measure optical density of liquid mixture, standard laboratory equipment (photocolorimeter and spectrophotometer) may be utilized.

EFFECT: enabled comparison of polymerizing activity of catalysts directly with respect to industrial feedstock.
