Hydrocarbon streams are hydrogenated catalytically without using a different solvent from the hydrocarbon stream to be hydrogenated, with a basic compound being added to the starting-material stream. The formation of undesired secondary components on the catalyst is thereby effectively prevented.

Process for catalytic hydrogenation

A supported metal oxide catalyst for the decomposition of ammonia and hydrogen cyanide in coke-oven gas is free of noble metals and comprises, based on the total catalyst, from 2 to 5.5% by weight of NiO and from 0.5 to 3.5% by weight of CoO on an MgO support. This catalyst is used in a process for the single-stage catalytic decomposition of ammonia and hydrogen cyanide in coke-oven gas before the latter is fed to a Claus desulfurization plant.
