据烃加工新闻5月29日消息称，据三位知情人士透露，美国亿万富翁卡尔·伊坎的CVR能源公司正在研究其炼油厂是否能够生产可持续的航空燃料。
可再生燃料仅占公路运输燃料的一小部分，但炼油商正努力寻找不同类型的原料，以减少温室气体排放。包括Valero和Phillips 66在内的炼油商正在探索用油脂、动物脂肪和植物油等原料生产更环保的航空燃料的方法，以脱碳，满足不断增长的需求。
CVR是一家商业炼油商，它已经宣布计划在今年第三季度在俄克拉荷马州的Wynnewood炼油厂生产可再生燃料，并表示正在探索在堪萨斯州的Coffeyville炼油厂生产可再生柴油的可能。
在生产可再生柴油的过程中，会产生一些可持续的航空燃料，但炼油商需要重新配置设备，以获得更高的产量。
据国际能源署称，未来几年，航空运输与乘用车或其他车辆相比不太可能实现电气化，该机构表示，该行业将不得不依赖低排放燃料。
伊坎告诉彭博新闻社，他相信可再生燃料将继续存在，并支持将补贴作为基础设施法案的一部分。
可持续航空燃料的倡导者说，可持续航空燃料的成本是传统航空燃料的三到四倍，如果没有政府的支持，就不经济。

CVR Energy explores producing sustainable aviation fuel
U.S. billionaire Carl Icahn’s CVR Energy Inc is exploring whether it can produce sustainable aviation fuel at its refineries, according to three sources familiar with the matter.
Renewable fuels account for just a fraction of the fuel for road transportation, but refiners are trying to source different types of feedstock to reduce their greenhouse gas emissions. Refiners, including Valero and Phillips 66, are exploring ways to produce greener aviation fuel from feedstocks such as grease, animal fats and plant oils, to decarbonize and meet rising demand.
CVR, a merchant refiner, has already announced plans to produce renewable fuels at its Wynnewood, Oklahoma, refinery in the third quarter of this year and said it is exploring options to produce renewable diesel at its Coffeyville, Kansas refinery.
Some sustainable aviation fuel is created in the process of producing renewable diesel, but refiners would need to reconfigure their units to produce it at higher yields.
Airline transport is less likely than passenger cars or other vehicles to be electrified in coming years, according to the International Energy Agency, which said in a recent report that the sector will have to depend on lower-emission fuels.
Icahn told Bloomberg News that he believes renewable fuels are here to stay, and supports subsidies as part of an infrastructure bill.
Sustainable aviation fuel costs three or four times more than traditional jet fuel, making it uneconomical without government support, according to advocates of the fuel.
