HEFA是目前唯一实现商业化运行的成熟SAF生产路线，当前绝大部分欧洲、亚洲SAF的生产均采用该技术路线，如芬兰 Neste 、法国 Total Energy 等。

HEFA (Hydroprocessed Esters and Fatty Acids), also called HVO (Hydrotreated Vegetable Oil), is a renewable diesel fuel that can be produced from a wide array of vegetable oils and fats. The term HEFA or HVO is used collectively for these biogenic hydrocarbon-based renewable biofuels. HVO is free of aromatics and sulfur and has a high cetane number.

2022年9月9日 · ②烃基生物柴油 (HVO)：第二代生物柴油，也称可再生柴油 (Renewable Diesel)。 指的 是把生物油脂通过加氢脱氧、异构裂化反应，最终生成与石油基几乎无差异的直链烷烃 和支链烷烃柴油，在化学结构上与一般柴油已无不同，可以无需掺混直接车用。 ③可持续航空燃料 (SAF)：一种将生物制造的绿色航油与传统燃油按一定比例混合的新兴 航空燃料，其二氧化碳排放量相较于传统航空燃料能够减少 80%。 1.2. 需求端：减碳政策推高生物柴油需求，欧 …

Hydrotreated Esters and Fatty Acids (HEFA) HEFA refines vegetable oils, waste oils, or fats into SAF through a process that uses hydrogen (hydrogenation). In the first step of the HEFA process, the oxygen is removed by hydrodeoxygenation. Next, the straight paraffinic molecules are cracked and isomerized to jet fuel chain length.

Hydrogenated vegetable oil (HVO) is a renewable diesel which can be produced from various vegetable oils and fats which contain triglycerides and fatty acids. The term HVO is used for renewable diesel fuels derived from hydrogenation and hydrocracking of different feedstocks such as tall oil, rapeseed oil, waste cooking oil, and animal fats.

2015年11月9日 · Currently, HEFA fuels are approved by ASTM International for use in jet engines at up to a 50% blend rate with petroleum jet fuel. The most common HEFA biofuel production to date has been a diesel replacement fuel alternately marketed as hydrotreated vegetable oil (HVO) abroad, or as renewable diesel in the United States.

2022年7月22日 · 生物燃料（Biofuel）主要包括燃料乙醇、生物柴油、航空生物燃料。生物柴油根据结构分为脂肪酸甲酯(FAME)、氢化油(HVO/HEFA)， 狭义上生物柴油指脂肪酸甲酯/乙酯。

公司积极开展烃基生物柴油（hvo）的开发工作，于 2019 年成功开发以废油脂为资源采 用固定床催化加氢脱氧、加氢异构工艺制备烃基生物柴油（hvo）的应用新技术，“废油 脂制备烃基生物柴油技术研究”项目已于 2021 年进入小试阶段；相较于酯基生物柴油， hvo ...

2024年12月26日 · HEFA 是综合竞争力最强的成熟 SAF 生产路线。 此路线可使用工业级混合油 （UCO）、棕榈酸化油（POME）或其他动植物油和脂肪加工提炼成 SAF，一般包 括预处理、加氢脱氧、异构降凝等流程，最后经过分馏将混合的液体燃料分离为 低凝生物柴油、生物石脑油和 SAF。 目前，此技术路线已在全球范围内处于成熟 水平，当前绝大部分 SAF 的生产均采用该技术路线，如芬兰 Neste、法国 Total Energy 等。 对于我国而言，国家层面发展生物质能源有“不 …

Abstract — Both Fischer-Tropsch (FT) and Hydroprocessed Esters and Fatty Acids (HEFA) Synthetic Paraffinic Kerosine (SPK) fuels are considered as leading alternative replacements for conventional jet fuel.
