摘要

尾氣處理是清潔柴油廢氣之最有效方法。柴油中之硫化合物卻損害尾氣處理之觸媒。因此，美國環保署乃討論修訂公路柴油之硫含量為15ppm，並將於2006年執行。煉油業者不得不依法製造並供應此超低硫柴油。在本文中，就加氫脫硫的化學及技術加以回顧討論，並提出製造超低硫柴油的具體技巧。煉油業可以考量其技術可行性、操作彈性、擴展可能性、資本投資以及總共費用來選擇最適組合及有效運用現有設備來生產超低硫柴油。

It becomes apparent that after-treatment is the most effective means of cleaning up diesel exhaust. The sulfur compound in the diesel fuel impairs the operation of the catalytic after-treatment devices. Thus, the US EPA issued revised requirements of 15 ppm sulfur in on-highway diesel, effective in 2006. In order to stay in business, refiners have to make such Ultra Low Sulfur diesel (ULSD) as mandated. In this paper, the chemistry and technology of hydrodesulfurization are reviewed. The options for ULSD production are described. Different combinations of options are possible and should be evaluated for technical feasibility, operation flexibility, expansion capability, capital investment and overall cost. The refiners can choose the best options to make best use of the existing facilities to minimize the capital and operation expenses in producing ULSD.
