Abstract
The present invention relates to a process for the preparation of non-pyrophoric catalyst having controlledparticle size and activity comprising suspending active charcoal of homogeneous pore distribution in a diluted solution of a palladium salt or salt complex, if desired in the presence of an aliphatic alcohol, stirring the solution, filtering the catalyst coal, followed by treatment of the sorbed palladium salt or salt complex with alkali if desired and stirring it as long as required for the accumulation of the sorbed palladium compounds, reducing same by methods known, repeating the above mentioned steps, if desired any number of times and drying the obtained catalyst after washing.
