Abstract: Alkines, dienes, and/or singly unsaturated hydrocarbons; compounds containing sulphur, arsenic and/or antimony; oxygen, hydrogen and/or carbon monoxide are removed from material flows in a total of at most three process steps. In a first process step, after hydrogen has been added to the feed material flow at a hydrogenation catalyst which is largely resistant to compounds containing sulphur, arsenic and/or antimony, alkines, dienes and/or singly unsaturated hydrocarbons are removed by hydrogenation, oxygen which may optionally be present also being at least partially removed by hydrogenation. In a second process step, compounds containing sulphur, arsenic and/or antimony and/or residual oxygen from the first process step are removed by absorption on a contact mass, and/or residual oxygen, carbon monoxide and/or residual hydrogen are at least partially converted catalytically into water and carbon dioxide. Optionally, in a third process step, residual carbon monoxide and/or residual hydrogen from the preceding process steps is/are converted on a contact mass into carbon dioxide and/or water.

Abstract: Catalyst contains 0.05-1.0 wt.% of a group 10 metal (compound) and 0.05-1.0 wt.% of a group 11 metal (compound). The weight ratio of the group 11 metal to the group 10 metal is 0.95-1.05. The catalyst is supported on a silicon dioxide support having a BET surface area of 2-400 m /g. At least 20% of the total pore volume of the catalyst is present in pores having a diameter above 100 nanometers An Independent claim is also included for a process for removing alkynes, dienes and simple unsaturated hydrocarbons and/or oxygen from material streams by reacting the material stream with hydrogen over a catalyst containing 0.05-1.0 wt.% of a group 10 metal (compound) and 0.05-1.0 wt.% of a group 11 metal (compound).
