丙烯是石化行業(yè)總量第二大的重要有機原料，2014年的全球丙烯需求量約為8900萬噸。業(yè)內(nèi)人士近日表示，可以預(yù)計，未來幾年北美地區(qū)乙烯裂解裝置得到的丙烯數(shù)量將一路下滑，石化行業(yè)必須轉(zhuǎn)向其他來源以保證丙烯需求，幾種專產(chǎn)丙烯工藝技術(shù)將大顯身手。
2025年全球丙烯需求或增至1.32億噸
盡管從產(chǎn)量方面來看，丙烯不及乙烯，但丙烯衍生物制備及供應(yīng)來源比乙烯復(fù)雜。從需求方面看，聚丙烯目前仍是需求最大的丙烯衍生物。
此外，以丙烯為原料還可以生產(chǎn)出多種多樣的特種化學(xué)品，包括應(yīng)用廣泛的異丙苯產(chǎn)品鏈、環(huán)氧丙烷、丙烯酸、丙烯腈、正丁醇、2-乙基己醇和異丙醇等。
