Unit process data for bio-jet fuel production from poplar biomass via bioconversion at a biorefinery

A partial Life Cycle Assessment (LCA) is conducted to investigate the life cycle impacts of a biorefinery designed to convert poplar tree chips into jet fuel via fermentation and subsequent hydrogenation. The goal of producing jet fuel from Populus (poplar) trees (bio-jet) is to create an alternative to petroleum based jet fuel (petro-jet). Currently no jet fuel producing biorefineries are in commercial operation and the results of this LCA will be used to assess a potential environmental impact that could result from scaling up the proposed system. Work is part of the Advanced Hardwood Biofuels Northwest project. The LCA does not include any proprietary information and is suitable for release to the public domain. Life cycle inventory assessment and conclusion are not included in this document.

The biorefinery in this LCA is assumed be located somewhere in the continental U.S and will produce jet fuel similar to Jet-A fuel with a high heating value (HHV) of 45.5 mega joule (MJ) / kilogram (kg) and a density of 0.820 kg/ liters (L). The biorefinery is designed to operate using 3200 bonne dry tonnes (BDt) of poplar chips per day (1.1 million BDt/yr). It is predicted to produce 300 L/ BDt (380 million L per year) of bio-jet fuel per year. The biorefinery is simulated in ASPEN-Plus v.2004.1chemical engineering software (Aspen Technology Inc., 2005). The LCA work is performed using SimaPro v.8.0 LCA software (Pre Consultants, 2012).

本研究开展部分生命周期评估（Life Cycle Assessment, LCA），以探究一座以杨树片为原料、经发酵及后续加氢工艺制备航空燃料的生物炼制厂的全生命周期环境影响。以杨属（杨树）为原料制备航空燃料（生物航空燃料，bio-jet）的目标，是替代石油基航空燃料（petro-jet）。当前尚无商业化运行的航空燃料生产生物炼制厂，本次LCA的结果将用于评估该拟建系统规模化投产后可能产生的潜在环境影响。本研究隶属于西北先进硬木生物燃料项目（Advanced Hardwood Biofuels Northwest）。

本次LCA未包含任何专有信息，可公开至公共领域。本文件未涵盖生命周期清单评估与结论部分。

本次LCA中的生物炼制厂假设位于美国本土地区，其产出的航空燃料与Jet-A燃料性能相近，高热值（High Heating Value, HHV）为45.5兆焦（MJ）/千克（kg），密度为0.820千克/升（L）。该生物炼制厂设计日处理杨树片3200绝干吨（BDt），即年处理量110万绝干吨。预计年产生物航空燃料300升/绝干吨，合计3.8亿升/年。该生物炼制厂通过ASPEN-Plus v.2004.1化工模拟软件（Aspen Technology Inc., 2005）进行建模仿真。本次LCA工作依托SimaPro v.8.0生命周期评估软件（Pre Consultants, 2012）完成。
