BP下屬Downstream科技公司在2013年年底公布了其“綠色”乙烯生產(chǎn)流程，命名為“蜂鳥(niǎo)”。經(jīng)過(guò)10年的研發(fā)，BP成功開(kāi)發(fā)出優(yōu)化的工藝流程，采用溫和的操作條件及高效HPA催化劑進(jìn)行乙醇脫氫。此工藝流程中，乙醇首先進(jìn)行脫水生產(chǎn)乙醚中間產(chǎn)物，再通過(guò)乙醚脫水生產(chǎn)乙烯。工藝的關(guān)鍵是如何調(diào)整工藝條件，避免產(chǎn)生不需要的副產(chǎn)品。Atol工藝由道達(dá)爾和IFPEN合作開(kāi)發(fā)。道達(dá)爾在比利時(shí)費(fèi)盧依的研究中心開(kāi)發(fā)了高性能催化劑ATO201的配方，IFPEN對(duì)新工藝進(jìn)行了改進(jìn)，尤其是能量回收方面的性能，IFPEN子公司Axens則基于能效改進(jìn)了催化劑配方和流程圖。該生物乙烯工藝可直接和下游生產(chǎn)裝置集成。目前已開(kāi)發(fā)出生物EO的集成工藝。
