Title:
潤滑油ベース原料を製造するためのオレフィンの二量化
Document Type and Number:
Japanese Patent JP2004521170
Kind Code:
A
Abstract:
Lube base stock compositions, and methods for preparing the compositions, are disclosed. The methods involve subjecting a predominantly C5-11 olefin-containing feedstock to dimerization conditions, preferably using nickel ZSM-5 as the dimerization catalyst, to give a first product where the majority of the olefins in the olefinic feed are converted to hydrocarbons predominantly in the C10-22 range. The first product, optionally combined with an olefin-containing feed in the C10-22 range, preferably in the C12-18 range, is subjected to an additional dimerization step, using the same or a similar dimerization catalyst, to provide a second product that includes hydrocarbons in the lube base stock range. The olefinic feedstock may include paraffins as well as olefins, which paraffins do not participate in the dimerization reactions. Accordingly, the second product includes relatively heavy hydrocarbons in the lube base stock range, as well as the relatively light unreacted paraffins (and any unreacted olefins). The hydrocarbons in the lube base stock range can be readily separated, for example, via distillation. In one embodiment, at least a portion of the olefin-containing feeds is derived, in whole or in part, from Fischer-Tropsch synthesis.
