| Abstract: | Kinetic dependences of the catalyst deactivation rates and poison concentrations on the partial pressures of the main reactants have been established. Numerical values for the kinetic constants are given. Poison chemisorption is shown to take place on both unoccupied and occupied active centers and also on the adsorption centers not involved in the main process.
