Effect of pretreatment conditions on the activity and selectivity of Pt/Al2O3 reforming catalysts

Reaction Kinetics and Catalysis Letters Aims and scope Submit manuscript

Abstract

The optimal reduction conditions for Pt/Al2O3 vary depending on whether the catalyst is fresh or lined-out and chlorine is present or absent. Optimal pretreatment conditions proposed by previous workers for fresh catalysts therefore have no meaning for industrial reformers since reforming catalysts spend most of their life under line-out conditions. Results from this work lend support to the strong hydrogen chemisorption theory.

Abstract

Оптимальные условия восстановления Pt/Al2O3 зависят от того, свежим ли является катализатор или он обработан, а также от присутствия или отсутствия хлора. Оптимальные условия предварительной обработки, предлоьенные ранее для свежих катализаторов, однако, не приемлемы для промышленных печей крекинга, т.к. катализаторы крекинга большинство времени проводят в условиях производства. Результаты этой работы подтверждают теорию сильной хемосорбции водорода.
