Abstract: In a process for removing oxygen from a C4-hydrocarbon stream comprising free oxygen by catalytic combustion, in which the hydrocarbon stream comprising free oxygen is reacted by catalytic combustion over a catalyst bed in the presence or absence of free hydrogen to give an oxygen-depleted hydrocarbon stream, the catalytic combustion is carried out continuously, the entry temperature in the catalyst bed is at least 300° C. and the maximum temperature in the catalyst bed is not more than 700° C.
