Glycerol is the main by-product of biodiesel plants, and new technological routes using it as a raw material are being developed due to the increased global production of biofuels. One possible application is in the production of acrylonitrile, a product with several industrial applications. Here, the production process of acrylonitrile using crude glycerol is proposed and analyzed. The process is shown to be economically viable, requiring an operating time of 5 years to achieve a net present value/investment ratio greater than 2 and an internal rate of return greater than 10 % per annum. The new process was found to be competitive compared to the current route (through propylene ammoxidation), supporting the development of new studies on this new route.

粗甘油生产丙烯腈的技术经济分析

甘油是生物柴油厂的主要副产品，随着全球生物燃料产量的增加，正在开发使用甘油作为原材料的新技术路线。一种可能的应用是丙烯腈的生产，丙烯腈是一种具有多种工业应用的产品。在此，提出并分析了使用粗甘油生产丙烯腈的工艺。该过程被证明是经济可行的，需要 5 年的运营时间才能实现大于 2 的净现值/投资比率和大于 10% 的内部年回报率。与当前路线（通过丙烯氨氧化）相比，新工艺被发现具有竞争力，支持对这条新路线的新研究的发展。
