The invention discloses a process for carrying reaction, rectifying and coupling to selectively hydrogenate to remove MAPD (Methylacetylene Propadiene) from refined propylene. A C3 fraction directly enters a propylene rectification tower or enters the propylene rectification tower after being pre-transformed by a first MAPD reactor; the MAPD is enriched into a stripping section and a tower kettlein the propylene rectification tower; and liquid is collected from a higher MAPD concentration position in the propylene rectification tower, is mixed with hydrogen to enter a second MAPD reactor andthen return to the propylene rectification tower. The treatment of the C3 fraction realizes the effective separation of the propylene and the MAPD, thereby increasing the selectivity of converting the MAPD into the propylene and realizing the purpose of increasing the yield of the propylene. In addition, the requirement of catalyst activity in the MAPD converting process is greatly reduced.
