The potential of squalene recovery from oil deodorizer distillates (ODD) via a combination of supercritical ethanol esterification, supercritical CO₂-extraction and additional purification was assessed via detailed process simulations. The squalene yields and purity from olive, sunflower and soybean ODD were determined. The highest squalene yield and purity could be achieved starting from olive ODD (95 g_squalene kg⁻¹_ODD, 99 wt% pure), followed by soybean ODD (31 g_squalene kg⁻¹_ODD, 98 wt% pure) and sunflower ODD (24 g_squalene kg⁻¹_ODD, 98 wt% pure). Apart from squalene, two more value-added products can be produced, i.e., high purity ethyl esters (>88 wt%) and a mixture of tocopherols and sterols. On a scale of 1 kTonne_ODD per year, all feedstocks demonstrate economical potential in Europe. Even more, a flexible process configuration could be designed which is suitable for the treatment of the different feedstocks.

通过详细的过程模拟，评估了通过超临界乙醇酯化，超临界CO ₂萃取和其他提纯相结合从石油除臭剂馏出物（ODD）中回收角鲨烯的潜力。测定了来自橄榄，向日葵和大豆ODD的角鲨烯的产率和纯度。从橄榄ODD（95 g_角鲨烯 kg ^-1 _ODD，纯度为99 wt％）开始，然后是大豆ODD（31 g_角鲨烯 kg ^-1 _odd，纯度为98 wt％）和葵花籽ODD（ 24 g_角鲨烯 kg ^-1 _ODD，纯度为98 wt％）。除角鲨烯外，还可以生产另外两种增值产品，即高纯度乙酯（> 88 wt％）以及生育酚和甾醇的混合物。以每年1吨_ODD的规模，所有原料在欧洲都具有经济潜力。甚至可以设计出一种灵活的工艺配置，适用于不同原料的处理。
