抗爆劑

目前(qian)，提(ti)高辛烷值的途(tu)徑有二種：一(yi)是(shi)通過設備工藝加工達到(dao)提(ti)高

辛烷值的目的，如(ru)催化(hua)(hua)裂(lie)化(hua)(hua)重整、化(hua)(hua)、異(yi)構化(hua)(hua)等;二是通(tong)過添加

抗爆劑(如現已禁用(yong)的四鉛)或添加高辛烷值組(zu)份(如MTBE增加芳烴

量等)。

工藝(yi)法雖(sui)是提(ti)高辛烷值(zhi)的主要手段，但存在(zai)著投資(zi)大，改變(bian)餾

程等問題，往(wang)往(wang)不易實現生產(chan)組合和缺乏適度的靈活性(xing)

對(dui)于(yu)低粘(zhan)(zhan)(zhan)度介質，用小直徑的(de)(de)(de)高(gao)轉速的(de)(de)(de)攪(jiao)拌器就能(neng)帶動(dong)周圍的(de)(de)(de)流(liu)體循環，并至遠處。而(er)高(gao)粘(zhan)(zhan)(zhan)度介質的(de)(de)(de)流(liu)體則不然(ran)，需直接(jie)用攪(jiao)拌器來推動(dong)。 適用于(yu)低粘(zhan)(zhan)(zhan)和(he)中(zhong)粘(zhan)(zhan)(zhan)流(liu)體的(de)(de)(de)葉(xie)(xie)輪(lun)(lun)有(you)(you)槳式(shi)(shi)、開啟(qi)渦輪(lun)(lun)式(shi)(shi)、推進式(shi)(shi)、長薄葉(xie)(xie)螺(luo)旋(xuan)槳式(shi)(shi)、圓盤渦輪(lun)(lun)式(shi)(shi)、布魯馬金式(shi)(shi)、板框槳式(shi)(shi)、三葉(xie)(xie)后(hou)彎式(shi)(shi)、MIG式(shi)(shi)等(deng)。適用于(yu)高(gao)粘(zhan)(zhan)(zhan)和(he)特(te)高(gao)粘(zhan)(zhan)(zhan)流(liu)體的(de)(de)(de)葉(xie)(xie)輪(lun)(lun)有(you)(you)螺(luo)帶式(shi)(shi)葉(xie)(xie)輪(lun)(lun)、螺(luo)桿式(shi)(shi)、錨式(shi)(shi)、框式(shi)(shi)、螺(luo)旋(xuan)槳式(shi)(shi)等(deng)。有(you)(you)的(de)(de)(de)流(liu)體粘(zhan)(zhan)(zhan)度隨反應進行而(er)變化，就需要(yao)用能(neng)適合寬粘(zhan)(zhan)(zhan)度領域的(de)(de)(de)葉(xie)(xie)輪(lun)(lun)，如泛能(neng)式(shi)(shi)葉(xie)(xie)輪(lun)(lun)等(deng)。
