摘要: Abstract Desorption of potassium from the industrial iron catalysts for ammonia synthesis and reference compound KAlO2 was monitored by surface ionisation detection. Activation energies desorption are close to each other within narrow range 1.7–1.8 eV: KAlO2, Polish catalyst PS3-INS boiled in water its precursor kept moist atmosphere two years. The coincidence includes also literature values AS-4 deactivated usage an reactor five data obtained confirm concept Somorjai that formation aluminate implies deactivation
