摘要：

In　order　to　understand　the　concentration　characteristics　of　VOCs　species　emitted　from　crude　oil　refinery,　VOCs　were　sampled　at　the　boundary　of　a　refinery　from　May　to　September　in　2011　by　using　SUMMA　canisters,　and　then　were　analyzed　by　gas　chromatography-mass　spectrometry(GC-MS)　to　get　the　mixing　ratio　of　each　VOC　in　the　boundary　area　in　spring,　summer　and　autumn.　Finally,　about　50　VOCs　species　were　detected,　C3-C8　hydrocarbons　accounting　for　more　than　80%　of　the　total　VOCs　in　volume,　in　which　alkenes　with　the　volume　contribution　of　more　than　50%.　In　addition,　maximum　increment　reactivity　(MIR)　was　used　to　quantify　the　ozone　formation　potential　of　various　VOCs　species　emitted　from　the　refinery.　The　results　showed　that　although　the　volume　percentage　of　alkanes　was　much　higher　than　that　of　alkenes　in　the　refinery　boundary,　alkenes　had　the　maximum　photochemical　ozone　formation　potential,　which　contributed　over　53%　in　the　ability　of　ozone　formation　by　all　VOCs　sepcies.
