This　paper　summarizes　the　research　progress　of　waste　tire　pyrolysis　technology　in　recent　years,　mainly　discusses　the　pyrolysis　technology　of　waste　tires　such　as　low　temperature　vacuum　pyrolysis　technology,　co-pyrolysis　technology　and　catalytic　pyrolysis　technology,　and　describes　pyrolysis　equipment,　temperature,　pressure　and　catalyst.　Consequently,　it　is　devoted　to　compare　the　influences　of　pyrolysis　carbon　black　on　pyrolysis　reactors,　temperature,　pressure,　catalysts,　etc.　In　addition,　the　comparison　of　different　modified　upgrade　methods　are　also　investigated.　Further　recycle　utilization　of　pyrolytic　carbon　black　is　also　summarized.　©　All　Right　Reserved.
