FIELD: technological processes.
SUBSTANCE: invention relates to the testing of the characteristics of zeolite materials, in particular to the assessment of resistance to deactivation in catalytic reactions. Pre-conduct the heating of the zeolite catalyst in the reactor in a flow of carrier gas, inert in the process of oligomerization, and then carry out the process of catalytic oligomerization under pressure in three stages. In the first and third stages, the process is conducted at 380–450 °C, and in the second stage at 450–600 °C. Proposed parameters of the three stages. After the first and third stages, the values of the degree of conversion are determined, and the resistance of the tested catalyst to deactivation is estimated by the difference between the obtained values.
EFFECT: invention provides the possibility of rapid testing, allowing for several hours to assess the resistance to deactivation of the test sample.
