Deuterium Exchange Study for Hydrogenation of D5-1-Pentene (4,4,5,5,5) Over Conventional Cobalt Fischer–Tropsch Catalyst

Abstract

The hydrogen-deuterium exchange reaction was performed for hydrogenation of D 5 -1-pentene (4,4,5,5,5) under realistic cobalt Fischer-Tropsch synthesis conditions. In the presence of CO, the added deutero-1-pentene did not show any significant H/D exchange but a step-wise H/D exchange occurs when CO was replaced with N 2 . The inhibition effects of CO and other FT products on H/D exchange of D 5 -1-pentene and a pressure dependency effect on H/D exchange are observed.

“…A significant inhibition of the catalyst in the presence of carbon monoxide was observed. [68,69] In material science, the study of HIE in understanding hydrogen storage and dissociation processes is of fundamental importance. In one example, HIE was studied in polycrystalline tungsten at 320 and 450 K. It was concluded that hydrogen does not freely diffuse through hydrogen saturated layers.…”
