Process for the depyrophorization of pyrophoric metal catalysts and catalysts prepared by the process

A process has been developed for the depyrophorization of pyrophoric metal catalysts, such as Raney nickel catalysts, which comprises treating said pyrophoric metal catalysts in water and/or an organic solvent with an organic nitro compound or a nitroso compound. The catalysts which are obtained acc...

More Information
Summary:A process has been developed for the depyrophorization of pyrophoric metal catalysts, such as Raney nickel catalysts, which comprises treating said pyrophoric metal catalysts in water and/or an organic solvent with an organic nitro compound or a nitroso compound. The catalysts which are obtained according to the process of the invention are useful for carrying out all hydrogenation reaction which can be carried out using the corresponding pyrophoric catalysts. The catalysts obtained are further distinguished by high activity and extended life. They are not contaminated by contact catalyst poisons and can be used essentially without pre-activation.
