項目簡介及效益分析:項目簡介:丁二烯是一種重要的石油化工基礎有機原料和合成橡膠單體,是C4餾分中最重要的組分之一,在石油化工烯烴原料中的地位僅次于乙烯和丙烯。丁二烯主要用于合成順丁橡膠、丁苯橡膠、丁腈橡膠、SBS彈性體、ABS樹脂等產品,此外還可用于生產己二腈、己二胺、尼龍66、1,4-丁二醇等有機化工產品以及用作粘接劑、汽油添加劑等,用途十分廣泛。丁烯氧化脫氫制備丁二烯催化劑是本公司自行研發的鐵系多元催化劑,利用鐵元素作為主催化劑,添加多種助催化劑,控制特定的生產工藝條件,提高了丁二烯的選擇性,減小了副反應的發生,降低了能耗。本公司目前具備年產500噸生產能力,催化劑已分別應用于10萬噸流化床和7萬噸固定床工業化裝置。


項目核心創新點:鐵系多元催化劑較其他類氧化脫氫相比具有選擇性高,活性高,操作溫度低,水烯比低,副反應少,操作范圍寬等多方面優勢。該催化劑同時適用于固定床和流化床兩種工藝。技術指標:丁烯轉化率≥75%; 催化劑選擇性≥90%;丁二烯收率≥65%; 操作溫度:295℃~360℃。


預期效益說明:2014年8月,國內丁二烯產能已達365.4萬噸/年,其中C4抽提工藝占86.9%,丁烯氧化脫氫工藝占13%。國營丁二烯生產企業均采用C4抽提工藝,成本低但開工負荷均不滿,所以中石化、中石油丁二烯基本以自供互供為主,外銷量很少。未來民營企業所占的比例將越來越大,且丁烯氧化脫氫法所占的比重將越來越大。因此,本項目將進一步推進氧化脫氫制備丁二烯行業的發展。
