產品介紹

石(shi)(shi)腦(nao)(nao)油(you)(you)(you)(you)(naphtha)是(shi)石(shi)(shi)油(you)(you)(you)(you)產(chan)品之(zhi)一，又叫化(hua)工輕(qing)油(you)(you)(you)(you)，是(shi)以(yi)(yi)原油(you)(you)(you)(you)或其他原料加工生產(chan)的(de)(de)(de)用(yong)(yong)(yong)(yong)于化(hua)工原料的(de)(de)(de)輕(qing)質(zhi)油(you)(you)(you)(you)，主要用(yong)(yong)(yong)(yong)作重整和化(hua)工原料。因用(yong)(yong)(yong)(yong)途不(bu)同(tong)有各種不(bu)同(tong)的(de)(de)(de)餾(liu)(liu)程，中國規定餾(liu)(liu)程為(wei)初餾(liu)(liu)點(dian)至220℃左右。作為(wei)生產(chan)芳(fang)烴的(de)(de)(de)重整原料時，采用(yong)(yong)(yong)(yong)70℃~145℃餾(liu)(liu)分，稱(cheng)輕(qing)石(shi)(shi)腦(nao)(nao)油(you)(you)(you)(you);當以(yi)(yi)生產(chan)高辛(xin)烷值汽油(you)(you)(you)(you)為(wei)目的(de)(de)(de)時，采用(yong)(yong)(yong)(yong)70℃~180℃餾(liu)(liu)分，稱(cheng)重石(shi)(shi)腦(nao)(nao)油(you)(you)(you)(you);用(yong)(yong)(yong)(yong)作溶(rong)劑(ji)(ji)時，則稱(cheng)溶(rong)劑(ji)(ji)石(shi)(shi)腦(nao)(nao)油(you)(you)(you)(you);來(lai)自煤焦油(you)(you)(you)(you)的(de)(de)(de)芳(fang)香族(zu)溶(rong)劑(ji)(ji)也(ye)稱(cheng)重石(shi)(shi)腦(nao)(nao)油(you)(you)(you)(you)或溶(rong)劑(ji)(ji)石(shi)(shi)腦(nao)(nao)油(you)(you)(you)(you)。

主要應用

主要用途： 可分離出多(duo)種有機原料，如汽(qi)油、苯(ben)、煤油、瀝青等。石腦(nao)油是一種輕質油品(pin)，由原油蒸(zheng)餾(liu)(liu)或石油二次(ci)加工切(qie)取(qu)相應餾(liu)(liu)分而得。其沸點范圍依需要而定，通(tong)常(chang)為(wei)較寬的(de)餾(liu)(liu)程，如30-220℃。

石(shi)(shi)腦(nao)油是管式(shi)爐裂(lie)解(jie)制取(qu)乙烯(xi)，丙烯(xi)，催化(hua)(hua)(hua)重(zhong)(zhong)整制取(qu)苯，甲苯，二(er)甲苯的(de)(de)重(zhong)(zhong)要(yao)原(yuan)料(liao)。作為(wei)裂(lie)解(jie)原(yuan)料(liao)，要(yao)求石(shi)(shi)腦(nao)油組(zu)成中烷(wan)烴(jing)和(he)環烷(wan)烴(jing)的(de)(de)含量(liang)不(bu)低(di)于70%(體積(ji));作為(wei)催化(hua)(hua)(hua)重(zhong)(zhong)整原(yuan)料(liao)用(yong)于生產高辛烷(wan)值汽(qi)油組(zu)分(fen)時，進料(liao)為(wei)寬餾(liu)分(fen)，沸(fei)點范圍一般為(wei)80-180℃，用(yong)于生產芳烴(jing)時，進料(liao)為(wei)窄(zhai)餾(liu)分(fen)，沸(fei)點范圍為(wei)60-165℃。國(guo)外(wai)常用(yong)的(de)(de)輕質(zhi)(zhi)直餾(liu)石(shi)(shi)腦(nao)油沸(fei)程(cheng)為(wei)0-100℃，重(zhong)(zhong)質(zhi)(zhi)直餾(liu)石(shi)(shi)腦(nao)油沸(fei)程(cheng)為(wei)100-200℃;催化(hua)(hua)(hua)裂(lie)化(hua)(hua)(hua)石(shi)(shi)腦(nao)油有<105℃，105-160℃及 160-200℃的(de)(de)輕、中、重(zhong)(zhong)質(zhi)(zhi)三種。實際關聯(lian)：由于石(shi)(shi)腦(nao)油市場價格遠低(di)于車(che)用(yong)無鉛(qian)汽(qi)油(噸價差達600-1200元)，使用(yong)石(shi)(shi)腦(nao)油和(he)石(shi)(shi)化(hua)(hua)(hua)助劑調配車(che)用(yong)無鉛(qian)汽(qi)油已成為(wei)民(min)營石(shi)(shi)化(hua)(hua)(hua)企業增加成品油利潤的(de)(de)重(zhong)(zhong)要(yao)方式(shi)。
