《綱要》明確炭黑企業(yè)的行業(yè)準入條件。據(jù)悉，“十二五”期間將不再新建規(guī)模在5萬噸以下的炭黑廠；不再建設(shè)產(chǎn)能在2萬噸以下（包括干法造粒和濕法造粒）的炭黑生產(chǎn)裝置。同時，主管部門還將限期淘汰總規(guī)模在5萬噸以下、技術(shù)裝備落后、能耗高、排放超標、作業(yè)環(huán)境不好的炭黑廠；立即淘汰規(guī)模在1.5萬噸以下的干法造粒的生產(chǎn)裝置。

style="text-indent:25px">1）燈黑生產(chǎn)工藝歷史上**早的炭黑生產(chǎn)法是燈黑生產(chǎn)工藝，在該工藝過程中，原料在直徑大至1.5 m的平坦的燃燒鐵盤上燃燒，含有炭黑的燃燒氣體由內(nèi)鋪有磚塊的排氣罩收集，然后通過彎管（彎折1/4）和通火管到達沉積的裝置。為了控制所產(chǎn)炭黑的特性，應(yīng)當保證在燃燒盤和排氣罩之間的間隙附近，原料主要作不完全燃燒。而在稍進管道里面，燃燒在氧氣不足下發(fā)生熱烈解，因而形成較大的炭黑顆粒，由于這些原因，組成較寬范圍的粒徑分布，主要特征為顆粒粗大。由于在燃燒盤和排氣罩間隙間形成的顆粒只有小部分能與空氣中的氧份接觸，因此這些炭黑只有少量的表面氧化物，相應(yīng)的pH值呈中性，并且揮發(fā)份極少。</p><div
