Abstract

Claims (62)

separating said first intermediate into different components, and removing wax, linear alkanes, or light boiling alkanes from said first intermediate, wherein said separating step is accomplished by at least one of: solvent dewaxing, urea dewaxing, distilling, fractionating, fractional crystallization, or light fraction stripping;

wherein either said white alkane or a second intermediate is produced.

6. The method of claim 5 , further comprising:

isomerizing said second intermediate; and

wherein either said white alkane or a third intermediate is produced.
