摘要
介绍了植物油加氢制备柴油的主要化学反应、工艺方法以及该项技术的工业化状况,分析了植物油直接加氢、先加氢后异构、直接脱羧工艺以及植物油与矿物柴油掺炼工艺的特点,阐述了各工艺采用的催化剂类型、工艺条件以及产品属性。指出了该领域存在的问题和研究方向。
In this review, the technology of hydroprocessing is introduced for producing hydrocarbon products in the diesel boiling range as effective diesel fuel ignition improvers, from vegetable oil. The chemistry in hydrotreatment of vegetable oil and commercial progress abroad are presented. The different processes used in manufacturing diesel with high cetane number from vegetable oil are described, covering direct hydrotreatment, hydrotreatment and isomerization complex, decarboxylation, and hydroconversion of the blend of vegetable oil and mineral oil, in addition the types of catalyst, process conditions and characteristics of products are illustrated. The existing problems and prospective research targets are also discussed.
