Abstract

CO and/or ethylene adsorbed on γ-Al2O3 was subjected to temperature programmed desorption (TPD). When temperature of the gas adsorbed specimens was linearly raised, two peaks were observed in desorption profile of both ethylene and that of CO. When an equimolecular misture of carbon monoxide and ethylene was adsorbed over the specimen, desorption temperature of CO(H) shifted to high temperature side of 87.2 °C, whereas that of ethylene (H) shifted to low temperature side of 33.0 °C. This behavior of desorption temperature might be attributed to a strong interaction in the two adsorbates induced by an electronic effect.

Abstract

Адсорбцию CO и/или этилена на γ-Al2O3 исследовали с помощью ТПД. При линейном повышении температуры наблюдали два пика в десорбционных профилях, характерных для этилена и CO. В случае адсорбции эквимолярной смеси моноокиси углерода и этилена температура десорбции CO(H) сдвигалась в направлении более высоких температур (87, 2°C), а этилена (H) в направлении более низких температур (33°C). Это объясняли, исходя из сильных взаимодействий между двумя адсорбатами за счет электронных эффектов.
