產品介紹

石(shi)(shi)腦(nao)(nao)油(you)(you)(naphtha)是石(shi)(shi)油(you)(you)產品之一，又叫化(hua)工(gong)(gong)輕油(you)(you)，是以原油(you)(you)或(huo)其他原料(liao)加工(gong)(gong)生(sheng)(sheng)產的用于(yu)化(hua)工(gong)(gong)原料(liao)的輕質油(you)(you)，主(zhu)要用作重整和化(hua)工(gong)(gong)原料(liao)。因用途不同有各種不同的餾(liu)程，中國規定餾(liu)程為(wei)初餾(liu)點至220℃左(zuo)右。作為(wei)生(sheng)(sheng)產芳烴的重整原料(liao)時，采(cai)(cai)用70℃~145℃餾(liu)分，稱(cheng)輕石(shi)(shi)腦(nao)(nao)油(you)(you);當以生(sheng)(sheng)產高辛烷值汽油(you)(you)為(wei)目(mu)的時，采(cai)(cai)用70℃~180℃餾(liu)分，稱(cheng)重石(shi)(shi)腦(nao)(nao)油(you)(you);用作溶劑(ji)時，則稱(cheng)溶劑(ji)石(shi)(shi)腦(nao)(nao)油(you)(you);來(lai)自(zi)煤焦油(you)(you)的芳香族溶劑(ji)也(ye)稱(cheng)重石(shi)(shi)腦(nao)(nao)油(you)(you)或(huo)溶劑(ji)石(shi)(shi)腦(nao)(nao)油(you)(you)。

主要應用

主要用途： 可分(fen)離(li)出(chu)多種有(you)機(ji)原料，如(ru)汽油、苯(ben)、煤油、瀝青等。石腦油是一種輕質油品，由原油蒸餾或石油二次加工切取(qu)相應餾分(fen)而得。其沸(fei)點范圍依需要而定，通(tong)常為較寬的餾程(cheng)，如(ru)30-220℃。

石腦油(you)(you)(you)(you)(you)是管式爐裂解(jie)制(zhi)取乙烯(xi)(xi)，丙(bing)烯(xi)(xi)，催化(hua)重(zhong)整(zheng)制(zhi)取苯，甲(jia)(jia)苯，二甲(jia)(jia)苯的(de)重(zhong)要原料(liao)。作(zuo)為(wei)(wei)(wei)(wei)裂解(jie)原料(liao)，要求(qiu)石腦油(you)(you)(you)(you)(you)組成(cheng)中烷烴(jing)和環(huan)烷烴(jing)的(de)含(han)量不低于70%(體(ti)積);作(zuo)為(wei)(wei)(wei)(wei)催化(hua)重(zhong)整(zheng)原料(liao)用(yong)于生產高辛烷值汽油(you)(you)(you)(you)(you)組分(fen)(fen)時，進(jin)料(liao)為(wei)(wei)(wei)(wei)寬餾(liu)分(fen)(fen)，沸(fei)點(dian)范(fan)圍(wei)一般為(wei)(wei)(wei)(wei)80-180℃，用(yong)于生產芳烴(jing)時，進(jin)料(liao)為(wei)(wei)(wei)(wei)窄餾(liu)分(fen)(fen)，沸(fei)點(dian)范(fan)圍(wei)為(wei)(wei)(wei)(wei)60-165℃。國(guo)外常用(yong)的(de)輕(qing)質(zhi)(zhi)直餾(liu)石腦油(you)(you)(you)(you)(you)沸(fei)程(cheng)為(wei)(wei)(wei)(wei)0-100℃，重(zhong)質(zhi)(zhi)直餾(liu)石腦油(you)(you)(you)(you)(you)沸(fei)程(cheng)為(wei)(wei)(wei)(wei)100-200℃;催化(hua)裂化(hua)石腦油(you)(you)(you)(you)(you)有<105℃，105-160℃及 160-200℃的(de)輕(qing)、中、重(zhong)質(zhi)(zhi)三種。實際關聯：由于石腦油(you)(you)(you)(you)(you)市場價格(ge)遠低于車用(yong)無鉛汽油(you)(you)(you)(you)(you)(噸價差達(da)600-1200元(yuan))，使用(yong)石腦油(you)(you)(you)(you)(you)和石化(hua)助(zhu)劑調配車用(yong)無鉛汽油(you)(you)(you)(you)(you)已成(cheng)為(wei)(wei)(wei)(wei)民營石化(hua)企業(ye)增加成(cheng)品油(you)(you)(you)(you)(you)利潤的(de)重(zhong)要方(fang)式。
