Abstract:

Under China's strategic goal of carbon peaking by 2030 and carbon neutralization by 2060, the petrochemical industry is facing huge challenges and urgently needs technological innovation. Biomass is the only renewable organic carbon source that can be converted into liquid fuels in the world. The huge volume of lignocellulose has the potential to prepare bulk energy chemicals. Large scale development and utilization is of great strategic significance for promoting ecological civilization, energy revolution, low-carbon economy, beautiful countryside, climate change, and carbon neutralization. This paper introduces and analyzes the concepts and application of biomass and lignocellulose, summarizes the latest research progress in pretreatment technology of lignocellulose to produce biogasoline and biodiesel through hydrogenation route and pyrolysis liquid upgrading technology, puts forward the commercial model of industrialization of producing liquid biofuel from lignocellulose through hydrogenation route, and discusses the technical route of cooperation between biofuels production enterprises and refinery and chemical enterprises.

Key words: biofuel hydrogenation, biomass, lignocellulose, biogasoline and biodiesel, pyrolysis liquid, hydrodeoxidation, hydrocracking, commercial model

摘要：

在中国2030年碳达峰、2060年碳中和战略目标下，石化行业面临巨大挑战，亟需技术创新。生物质是世界上唯一可转化为液体燃料的可再生有机碳源，体量巨大的木质纤维素具有制备大宗能源化学品的潜力，大规模开发利用对推动生态文明、能源革命、低碳经济、美丽乡村、气候变化、碳中和有重大战略意义。文中介绍并分析了生物质、木质纤维素的概念及应用状况，总结了将木质纤维素通过加氢路线生产生物汽柴油在预处理技术、热解液提质技术的最新研究进展，提出了木质纤维素通过加氢路线生产生物液体燃料工业化的商业模式，探讨了生物燃料生产企业与炼油化工企业开展合作的技术路线。
