摘要
市面銷售的潤滑油將持續面臨較高的性能需求，包括較小的揮發度，較好的抗氧化和熱穩定性，以及在寒冷氣候下仍具有很好的流動特性，而且在以後的日子裡，對於高性能潤滑基礎油的需求會更多，迫使煉油從業人員不保不尋找一種新穎的製造技術。 要滿足高性能基礎油的技術內容包括可以改善黏度指數，可以降低其流動點，並有精煉能力。 利用加氫精製的方法，其中加氫裂解或深度加氫處理可以改善黏度指數，使用觸媒加氫異構化的技術可以降低油料的流動點，油品精煉可以利用加氫精煉製程，而目前市面上可用的專利程序有Exxon-Mobil公司的MSDW製程和Chevron公司的異構化脫腊製程。 本文將詳細說明這些加氫處理技術和相關的技術資料。

Finished lubricants are continuously facing higher performance requirements in terms of reduced volatility, better oxidation and themal stability and improved cold flow properties. The strong increase in volume demand for higher quality base oils has forced the refiners to find an advance manufacturing technology. The technologies to accomplish the requirements for high quality of base oils are VI improvement, pour point reduction and better finishing. By hydroprocessing, VI improvement is achieved by hydrocracking or deep hydrogenating, pour point reduction by hydroisomerization and better finishing by hydrofinishing. The newly devised patents in commercial hydroprocessing technologies are Exxon-Mobil’s MSDW and chevron’s isodewaxing processes. This article describes the details of the hydroprocessing technology for lube base oils and related topics.
