Kinetics of oxidation of carbon monoxide on industrial copper-containing catalyst for fluidized bed
Abstract
Catalysts based on transition metal oxides are the most promising
for the efficient combustion of fuel in a fluidized bed. Afterburning
coke is a limiting stage of fuel combustion, characterized by the
release of carbon monoxide (CO) and its reacting with oxygen on the catalyst surface. Determination of the observed kinetic parameters of this process will further evaluate the efficiency of the catalyst, and optimize the performance of fluidized bed reactor. The study of the kinetics of CO oxidation on the industrial catalyst SCHKZ-1 (oxide aluminum-copper-chromium), currently used in the fluidized bed reactor when burning fuels. The studies carried out in conditions when the internal diffusion does not affect on the reaction rate. Kinetic parameters of the reaction were evaluated by a first order equation for CO and O2; the obtained values of activation energy and pre-exponential rate constants were respectively ko = 5,23·107 s–1, E = 32,8 kJ/mol. A comparison with published data showed their good correlation .
