???? 據(jù)ICIS網(wǎng)站4月6日休斯頓報(bào)道 西方石油公司的子公司西方石油低碳合資公司（OLCV）和生物技術(shù)公司Cemvita Factory計(jì)劃建立一個(gè)生物乙烯試驗(yàn)工廠，用人造二氧化碳（CO2）生產(chǎn)單體。
????該試驗(yàn)工廠的產(chǎn)能為1噸/月，利用二氧化碳、水和光生產(chǎn)生物乙烯，估計(jì)將于2022年啟動(dòng)。這些公司沒有透露將在何處建造這座工廠。
????這項(xiàng)技術(shù)與碳?xì)浠衔锷a(chǎn)的乙烯具有競(jìng)爭(zhēng)力，盡管兩家公司沒有具體說明價(jià)格。
????Cemvita公司首席技術(shù)官Tara Karimi表示，這一過程是通過從香蕉中提取一個(gè)基因，并通過基因工程將其植入Cemvita的微生物中開發(fā)。
????OLCV技術(shù)副總裁Robert Zeller表示，如果成功，該項(xiàng)目將為西方石油提供另一種乙烯來源，用于生產(chǎn)聚氯乙烯（PVC）。
????Cemvita表示，它的技術(shù)可以處理多種二氧化碳源，幾乎不需要調(diào)整。在最初的試驗(yàn)階段，它計(jì)劃從當(dāng)?shù)氐奶烊粴夤?yīng)商那里購買二氧化碳。
????該公司表示，稍后將使用天然氣燃燒產(chǎn)生的二氧化碳，可以利用直接從大氣中捕獲的二氧化碳。
????OLCV本身也參與了美國的幾個(gè)碳捕獲與封存（CCS）項(xiàng)目。

????US Occidental, biotech firm to build CO2-to-bioethylene pilot plant
????A subsidiary of Occidental Petroleum, Oxy Low Carbon Ventures (OLCV), and the biotechnology firm Cemvita Factory plan to build a bioethylene pilot plant that will produce the monomer from manmade carbon dioxide (CO2), the companies said on Tuesday.
????The pilot plant will have a capacity of 1 tonne/month and produce bioethylene using CO2, water and light. It should start up in 2022. The companies did not say where it will build the plant.
????The technology is competitive with ethylene produced from hydrocarbons, although the companies did not specify any prices.
????The process was developed by taking a gene from a banana and genetically engineering it into Cemvita's microorganism, said Tara Karimi, chief technology officer of Cemvita.
????If successful, the project could provide Occidental with another source of ethylene, which it uses to make polyvinyl chloride (PVC), said Robert Zeller, vice president of technology for OLCV.
????Cemvita said its technology can work with a a variety of CO2 sources with little or no modification. For the initial pilot phase, it plans to buy CO2 from a local gas supplier.
????Later it will use CO2 derived from burning natural gas, the company said. It could use CO2 captured directly from the atmosphere.
????OLCV itself is involved in several carbon capture and storage (CCS) projects in the US.
