The　selective　hydrogenation　of　nitrile　butadiene　rubber　(NBR)　is　an　important　process　for　the　preparation　of　high　value-added,　high-performance　hydrogenated　NBR　(HNBR).　The　C==C　double　bonds　in　the　chain　segment　are　hydrogenated　while　the　nitrile　group　is　unaffected,　which　can　not　only　maintain　its　original　oil　resistance　and　wear　resistance,　but　also　greatly　improve　its　weather　resistance　and　ozone　resistance.　This　article　introduces　several　processes　of　NBR　hydrogenation　and　emphatically　reviewed　the　research　progress　and　development　direction　of　NBR　heterogeneous　catalytic　hydrogenation.　The　effects　of　pore　structure,　surface　properties　and　the　active　components　of　the　supported　catalyst　on　the　hydrogenation　performance　of　NBR　is　discussed.　Additionally,　the　solvent　effect,　and　the　recovery　and　regeneration　of　catalyst　in　the　heterogeneous　hydrogenation　process　are　summarized.　It　is　proposed　that　solvent　has　an　important　influence　on　the　catalytic　hydrogenation　rate　and　hydrogenation　degree,　and　the　hydrogen　bond　acceptance　ability　(β　value)　of　solvent　is　the　key　factor　affecting　the　hydrogenation　performance.　The　main　cause　of　catalyst　deactivation　is　the　coverage　of　the　surface　active　sites　by　polymer,　and　washing　with　the　effective　solvent　or　modification　of　catalyst　surface　can　expose　the　active　sites　again,　thereby　restoring　the　hydrogenation　activity.　Finally,　the　future　research　directions　of　heterogeneous　catalytic　hydrogenation　for　high　value-added　HNBR,　including　catalyst　design,　solvent　effect　and　catalyst　regeneration,　are　prospected.　©　2022　Chemical　Industry　Press.　All　rights　reserved.
