摘要

Shell was the first oil marketer to commercialize Gas to Liquids (GTL) technology for base oilsrnproduction. This was occasioned by the commissioning of the Bintulu multi-purpose GTL facilityrnin 1993, which uses the Shell Middle Distillate Synthesis process to produce detergentrnfeedstocks, a range of Fisher-Tropsch commercial wax grades and a feedstock for base oilsrnproduction. This base oils’ feedstock, a so-called waxy raffinate, requires only a de-waxing steprnto produce a finished base oil which is essentially an iso-paraffinic base stock. The feedstockrnwas shipped to Shell facilities in both Japan and France from 1994 onwards where it wasrnsolvent de-waxed to produce the first commercially available GTL base oil in the market place.rnThis was a 5 cSt grade marketed as Shell XHVI. It was used to develop passenger car motorrnoils meeting ILSAC GF-2 and GF-3 specifications.rnShell has announced in 2003 its intention to build a two train world scale GTL facility in Qatarrnand this will include substantial base oils facilities producing a full grade structure from 2 cSt torn> 9 cSt (Vk 100℃) base oils grades. The lower viscosity grades will fall into the current API GprnII category and grades > 4 cSt will fall within the current API Gp III classification. These gradesrnwill show the superior additive responses expected of 100% saturates catalytically de-waxedrnbase oils.rnThe characteristics of the base oils will make them ideally suited to a range of automotive andrnindustrial fluid applications by virtue of the combination of both high VI and high Vk 100oC,rnwhere the upper limiting carbon number is not set by the intersection of cracking severity andrnlimiting crude oil carbon number – as is the case in severely hydro-cracked Gp II and Gp IIIrnbase oils. Data are presented which support this extension to the blending window.
