Abstract

Selective Blockage Of The Catalyst Active Sites For The Hydrogenation Of Various Functional Groups Over Raney Nickel And Nickel Supported On Silica

Nickel supported on silica and Raney nickel was used. Hydrogenation was carried out of compounds with >C=C< bond and -NO¬2 bond in different solvents with different degree of deactivation of the nickel catalysts. It is shown the usability of the method for analysis of poisoning behavior not only for gas reaction, but also for the liquid phase hydrogenation. It was shown that catalyst support as well as the media has a significant effect on the poisoning behavior. It was demonstrated while different reducible groups are hydrogenating there is different poisoning behavior
