Abstract
It is well known that nickel catalyst, which is used in catalytic hydrogenation, is very sensitive to heat. In general, at higher temperatures of the hydrogenation reaction the decrease of catalytic activity is more rapid. I think this may be due not only to external factors, such as poisoning of the catalyst, etc., but also to internal factors, such as metallurgical sintering, etc., and I have surveyed by means of the electron microscope the changes caused by heating Raney nickel catalyst.
