Zusammenfassung:	A regeneration method of a noble metal catalyst. The invention discloses a regeneration method of a low-carbon alkane dehydrogenation catalyst, by which a deactivated noble metal-based low-carbon alkane dehydrogenation catalyst recovers an excellent catalytic performance. The method includes the following steps: (1) under hydrogen atmosphere, treating the deactivated catalyst in a hydrogen donor solvent; and (2) treating the treated deactivated catalyst in the step (1) in a mixed atmosphere containing CO2 and N2O to obtain regenerated catalyst. The regeneration method of the low-carbon alkane dehydrogenation catalyst can allow the dehydrogenation activity of the regenerated catalyst to reach the level of a fresh catalyst. The regeneration method is simple in processes and is easy to carry out.
