Techno-economic and Environmental Assessments of SAF from Bioamss:An Review

This review presents a comprehensive techno-economic and life-cycle assessment of sustainable aviation fuel(SAF)production from biomass.The critical need for transitioning towards environmentally sustainable alternatives for liquid fuel and aviation industry is first discussed.Key insights encompass the evolutionary progression of biofuel production from first-generation to second-generation biofuels,with a focus on utilizing non-food sources like woody biomass for enhanced sustainability.Available data from the literature on techno-economic assessments of various SAF production pathways are analyzed including production costs,conversion efficiency,and scalability.Moreover,results of lifecycle assessments associated with different SAF production pathways are presented,providing essential insights for decision-making processes.The challenges of scaling up woody biomass-based SAF production are discussed based on the assessment results,and recommendations are proposed to steer stakeholders towards a greener and more sustainable trajectory for aviation operations.

国内博物馆公共教育活动困境分析与对策研究

近年来,随着经济的发展和政府对人民文化生活的日益重视,我国博物馆事业发展得越来越好,中国博物馆业在世界上也取得了较大的影响。越来越多的人进入博物馆充实文化知识、享受闲暇时间。然而观众数量的快速增长也带来了一系列问题,就公共教育而言,由于教育受众权重失衡、从业专业人才匮乏、投入资金额度偏小,使得国内公共教育在概念、内容、方式等方面低幼化特征明显。本文拟通过探悉国内现状与案例,结合我国国情,提出适合我国公共教育活动的思路与建议。
