Title:
METHOD FOR TESTING ACTIVATION ENERGY OF CATALYST
Document Type and Number:
WIPO Patent Application WO/2022/237192
Kind Code:
A1
Abstract:
A method for testing activation energy of a catalyst comprises: obtaining a changing curve of a resonant frequency variation over time by means of an integrated self-heating resonant cantilever beam (100), and converting the changing curve into a curve of a resonant frequency changing along with a temperature, and further converting the curve into a changing curve of a coverage degree along with the temperature; after first-order differential is performed, extracting a relevant parameter corresponding to a minimal value, then substituting the relevant parameter into a formula, so as to obtain a catalyst desorption rate constant and catalyst desorption activation energy, so that the test of the activation energy of the catalyst can be performed only by a one-time programed heating process; moreover, the test result is accurate, rapid and convenient, and a catalyst sample is small in consumption, and low in price.
