Verfahren zur Reinigung von Stoffströmen |
摘要 |
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.
