Abstract The global awareness to reduce greenhouse gas (GHG) emissions from aviation and thereby make the overall aviation sector more environmentally friendly has increased in recent years. In this context one main driver is seen in the development of advanced biofuels for aviation, which have already been used for some regular flights by various air carrier. Within this context this paper compares four different production processes for biokerosene located in northern Germany using two different types of biomass feedstock each. These conversion processes are then assessed in terms of technical, economic and environmental criteria based on data retrieved from an extensive process simulation. Main outcome of this analysis are mass and energy balances, kerosene production costs and GHG emissions for the investigated conversion routes. The results of the investigated criteria are scattering significantly; i.e. no “silver bulled” can be seen based on these findings. Nevertheless, the significant influence of the provision of the biomass feedstock becomes obvious. Generally spoken the more environmentally sound and economic viable the feedstock provision can be realized, the more promising is the resulting biokerosene related to the economic and environmental criteria assessed here. This result is more or less independent from the respective conversion route.

航空生物燃料的技术经济和环境分析

摘要 近年来，全球对减少航空温室气体 (GHG) 排放从而使整个航空部门更加环保的意识有所提高。在这种情况下，一个主要驱动因素是开发先进的航空生物燃料，这些燃料已被各种航空公司用于一些定期航班。在此背景下，本文比较了位于德国北部的四种不同的生物煤油生产工艺，每种工艺使用两种不同类型的生物质原料。然后根据从广泛的过程模拟中检索到的数据，根据技术、经济和环境标准对这些转化过程进行评估。该分析的主要结果是所研究转化路线的质量和能量平衡、煤油生产成本和温室气体排放。调查标准的结果显着分散；即，根据这些发现，看不到“银牛”。然而，提供生物质原料的显着影响变得明显。一般来说，原料供应越环保且经济可行，与此处评估的经济和环境标准相关的生物煤油就越有希望。该结果或多或少独立于各自的转化途径。更有希望的是由此产生的与经济和环境标准相关的生物煤油。该结果或多或少独立于各自的转化途径。更有希望的是由此产生的与经济和环境标准相关的生物煤油。该结果或多或少独立于各自的转化途径。
