“双碳”背景下《生物质能源开发与利用》课程新探索-木质纤维素催化转化制乳酸

New Course Exploration on Biomass Resource Utilization and Development under the Background of“Double Carbon”-Catalytic Conversion of Lignocellulose to Lactic Acid

本文围绕“碳达峰”与“碳中和”战略目标和“十四五”规划的关键背景,让学生了解可再生生物质能源概念,增强绿色化学理念和渗透力。采用浸渍法制备复合金属氧化钇固体酸催化剂,进一步用于生物质能源纤维素催化转化制备绿色化学品乳酸。通过精细调控催化剂表面酸性及酸量,优化催化剂活性,从而提高目标产物乳酸的产率。介绍生物质转化理论和技术,使学生牢固掌握和加深对生物质能源转化利用的认识,提高学生学习兴趣以及解决实际专业问题的能力,并提高教学质量目的。

This paper focuses on the strategic goals of“carbon peak”and“carbon neutrality”and the key background of the“14th Five-Year Plan”,which makes students understand the concept of renewable biomass resource and enhance the concept and penetration of green chemistry.The yttrium modified composite metal oxide solid acid catalyst was prepared by impregnation method,and further was applied for catalytic conversion of lignocellulose to produce green chemical lactic acid.The surface acidity and acid amount of catalyst was finely adjusted to optimize the catalytic activity,improving the yield of lactic acid.Through the introduction of biomass conversion theory and technology,students can firmly grasp and deepen the understanding of biomass conversion and utilization,and improve learning interest and ability as well as in solving practical professional problems,and simultaneously improve teaching quality.
