| 旨在为生物燃料产业可持续发展提供支撑，分析了废弃油脂中磷的来源、实际生产中磷对废弃油脂加氢装置运行的危害及机制、传统预处理脱磷工艺的局限性，并提出综合解决方案。在全球能源转型背景下，国内废弃油脂加氢技术虽有发展，但装置运行周期短的问题依然突出，绝大多数装置运行周期达不到设计值，其中原料磷含量高是一个关键影响因素。废弃油脂中的磷来源包括动植物油脂内源性贡献、食品添加剂引入及收集环节外源污染。磷会使加氢催化剂孔道堵塞、活性位点被覆盖、产生电子中毒效应，导致催化剂失活。传统预处理工艺在脱磷方面存在不足，而临氢预处理技术能深度脱磷。为实现废弃油脂加氢装置长周期运行，可采用“简单预处理脱磷+临氢预处理脱磷+固定床加氢精制”的集成工艺，通过整合原料预处理、催化剂创新与工艺控制，并利用在线检测与人工智能实现精准调控，同时在利好政策的引导下加速技术工业化，废弃油脂加氢产业有望实现1~2年的稳定运行周期。 |

| Aimed at supporting the sustainable development of the biofuel industry,the sources of phosphorus in waste cooking oil, the hazards and mechanisms of phosphorus on the operation of waste cooking oil hydrogenation units in actual production, and the limitations of traditional pretreatment dephosphorization processes were analyzed, thus an integrated solution was proposed. Against the backdrop of global energy transition, domestic waste cooking oil hydrogenation technology has advanced, but the issue of short operation cycles remains prominent, with most units failing to achieve their designed operational durations, among which high phosphorus content in the feedstock is a key influence factor. Sources of phosphorus in waste cooking oil include endogenous contributions from animal and vegetable oil, introduction from food additives, and exogenous contamination during collection. Phosphorus can block pores, cover active sites, and cause electronic poisoning of hydrogenation catalysts, leading to catalyst deactivation. Traditional pretreatment processes are insufficient in dephosphorization, whereas hydrotreating pretreatment technology enables deep dephosphorization.To achieve long-term operation of the units, an integrated process combining simple pretreatment dephosphorization, hydrotreating pretreatment dephosphorization, and fixed-bed hydrofining can be adopted. Simultaneously, by integrating feedstock pretreatment, catalyst innovation and process control, and utilizing online detection and artificial intelligence for precise regulation, along with accelerated industrialization under the guidance of favorable policies, the waste cooking oil hydrogenation industry is expected to achieve a stable operation cycle of 1-2 years. |
