据全球能源新闻2月14日消息称，在美国休斯顿举行的第25届全国乙醇大会上，NextChem和Saola能源公司宣布了一项新的合作计划，将利用植物油和残余脂肪生产可再生柴油的技术授权给国际市场。

NextChem和Saola能源公司将结合他们的专业知识，为市场提供全面的解决方案。NextChem将是合并技术的许可方，并将为客户提供工程、采购、施工服务和培训，以确保技术的成功部署。

Saola能源公司的专利技术包括一个加氢处理步骤，然后异构化，从油和残余脂肪中生产高质量的可再生柴油燃料。该技术可在工业规模、各种原料范围内进行处理。

此外，该工艺采用模块化方法，设想的年产能低至1000万加仑（约30000吨/年），使其非常适合小型的螺栓固定式工厂和有限的自给原料供应，以及较大的独立工厂可以聚集大量原材料。该技术与现有工厂(或生物精炼厂)的整合将通过副产品的定价优化其经济效益。处理废油和残余脂肪的公司将在第二代可再生燃料市场获得新的机会。

传统生物柴油和可再生柴油都可以从残余脂肪和植物油中提取，但它们的开发方式不同，生物柴油是通过酯交换反应生产的，可再生柴油是通过加氢处理和异构化生产的。尽管生物柴油存在与化石柴油混合的局限性，但可再生柴油是一种符合石油燃料EN 590和ASTM D975标准的直接燃料。它克服了混合限制，目前在现有的柴油发动机中没有任何约束，与化石燃料和生物柴油相比，它具有更优越的性能。可再生柴油要比生物柴油贵很多。

NextChem and Saola Energy to deliver renewable diesel technology

During the 25th edition of the National Ethanol Conference in Houston, US, NextChem and Saola Energy announced a new collaboration to license technology for the production of Renewable Diesel from vegetable oils and residual fats, to the international market.

NextChem and Saola Energy will combine their expertise to deliver a comprehensive solution to the marketplace. NextChem will be the licensor of the combined technology and will provide clients with Engineering, Procurement, Construction services and training to ensure successful deployment of the technology.

Saola Energy’s patented technology consists of a hydrotreatment step followed by isomerisation to produce high-quality Renewable Diesel fuel from oils and residual fats. The technology can process at an industrial scale, a wide range of feed stocks.

Furthermore, the process has a modularised approach and is conceived for capacities as low as 10 million gallons per year (approximately 30.000 tpy), making it ideal for both smaller bolt-on facilities with access to a limited supply of captive feedstock and larger standalone plants that can aggregate larger amounts of raw materials. The integration of this technology with existing plants (or bio-refineries) will allow the optimisation of their economics via the valorisation of by-products. Companies handling waste oils and residual fats will have access to new opportunities in the market for second generation renewable fuels.

Traditional biodiesel and renewable diesel can both be made from residual fats and vegetable oils but are developed differently, with biodiesel produced by transesterification and renewable diesel by hydrotreating and isomerisation. While biodiesel presents limits of blending with fossil diesel, renewable diesel is a drop-in fuel that meets the petroleum fuel EN 590 and ASTM D975 standards. It overcomes blend limits and is currently used in existing diesel engines without any constraint and with superior properties compared to fossil and biodiesel. Renewable diesel commands a substantial premium over biodiesel.
