脂肪酸甘油三酯转化为高值化学品和燃料的工艺概述
An Overview of the Process for the Conversion of Fatty Acid Triglycerides into High-value Chemicals and Fuels
摘要
Abstract
To advance the high-value utilization of biomass resources and facilitate the achievement of the"dual carbon"targets,this paper systematically elaborates on the reaction mechanisms and technical pathways for the catalytic transforma-tion of fatty acid triglycerides into oxygen-free fuels and high-value chemicals.Through the integration of catalytic conversion processes such as hydrodeoxygenation,isomerization cracking,and ketonization coupling,the influence of different catalyst systems on product distribution is emphatically explored.The results indicate that,1)Utilizing the Pt/Al2O3 catalyst can achieve a deoxygenation conversion rate of over 83％for vegetable oil,and the obtained straight-chain alkanes(C13-C18)possess combustion characteristics comparable to those of petroleum diesel.2)After isomerization cracking with SAPO-11 molecular sieve supported by bimetallic catalyst,the selectivity of jet fuel components(C8-C16)reached 58.2％,and its cold flow performance at-40℃ conformed to the standard of GSO ASTM D7566:2024"Specification for Hydrocarbon Fuels for Aviation Turbine Engines.3)Through the TiO2-catalyzed ketonization coupling of fatty acids and the Pt-MoOx deoxygenation process,co-production of lubricating base oil(C30-C54,viscosity index＞120)and green diesel is achievable,and the utiliza-tion rate of raw materials is increased by 27％.This research reveals the synergy mechanism between the acidic sites and metal components of the catalyst and points out that constructing a hierarchical pore structure can effectively inhibit coking deactivation.This technical system offers a multi-product solution for the resource utilization of bio-oils and holds significant practical value for the development of a circular economy.关键词
