ABSTRACT:
The invention is a process for separating a mixture of saturated hydrocarbons into normal paraffins, branched chain paraffins, and cyclic paraffins which comprises contacting said mixture with a series of two molecular sieves comprising a first silicalite and a second silicalite which have different retention conditions. One of the silicalites is selected so that it will retain normal paraffins and pass through branched chain paraffins and cyclic paraffins. The second silicalite is selected so that it will retain normal and branched chain paraffins and pass through cyclic paraffins. The two molecular sieves are employed in series so that the mixture of saturated hydrocarbons can be separated into normal paraffins, branched chain paraffins, and cyclic paraffins.
