摘要： 印度尼西亚共和国政府声明，用于热拌沥青生产的热能应通过直接燃烧化石燃料来提供，这些化石燃料有柴油、天然气或煤气化产生的煤气，它们可能产生温室气体排放。通过气化技术，生物质能够替代化石燃料。气化利用有限的空气将生物质转化为主要包含一氧化碳和氢气的气态燃料，这些燃料随后燃烧产生热量，二氧化碳和水。显然，植物随后吸收了二氧化碳进行光合作用，从而保持平衡的封闭循环。这项研究基于openLCA v1.9软件，测试了该系统的全球变暖潜能水平。本文分析使用了“门到门”方法来评估棕榈仁壳气化以生产1吨热拌沥青的情景。范围涵盖原材料供应和运输，棕榈仁壳气化以及产品。结果表明，气化有潜力减少二氧化碳排放量。使用openLCA中的Traci 2.1数据库进行环境影响分析并阐明结果，使用棕榈仁壳气化技术不仅可以供热，而且可以发电以替代所有电气设备，从而可以进一步减少二氧化碳排放。

Abstract: The Government of the Republic of Indonesia states that the thermal energy for hot-mixed asphalt production shall be supplied by the direct combustion of fossil fuels in the form of diesel oil, natural gas, or fuel gas from coal gasification which may generate GHG emission. Biomasses are able to substitute the fossil fuels through gasification technology. Gasification converts the biomass using limited air into gaseous fuel containing mainly CO and H2 that are subsequently combusted to produce heat, carbon dioxide, and water. It is obvious that the CO2 is then absorbed by the plants for photosynthesis, maintaining a balanced closed cycle. This study examines the level of global warming potential of this system for supplying heat based on the openLCA v1.9 software. The analysis used a gate-to-gate approach to evaluate scenarios of shell gasification to produce 1 metric tonne of hot-mixed asphalt. The scope covers raw material supply and transportation, palm kernel shell gasification, and products. The evaluation concludes that gasification could potentially reduce CO2 emissions. Environmental impact analysis and interpretation of the results using the openLCA database of Traci 2.1 recommend that greater CO2 emission reduction is possible using palm kernel shell gasification, not only for supplying heat but also for electricity generation to operate all electrical equipments.
