Abstract
A method for producing a linear paraffin product from natural oil and kerosene includes providing a first feed stream comprising kerosene, pre-fractionating the first feed stream to produce a heart cut paraffin stream comprising paraffins in a heart cut range, and combining the heart cut paraffin stream with a second feed stream comprising natural oil to form a combined stream. The method further includes deoxygenating the natural oil and fractionating the combined stream to remove paraffins that are heavier than the heart cut range.

A method for producing a linear olefin product from natural oil and kerosene comprising:
- providing a first feed stream comprising kerosene;
- pre-fractionating the first feed stream to produce a first heart cut paraffin stream comprising paraffins in a heart cut range;
- combining the first heart cut paraffin stream with a second feed stream comprising natural oil deoxygenating the natural oil to form a combined stream;
- fractionating the combined stream and removing paraffins that are heavier than the heart cut range to form a second heart cut paraffin stream;
- and
- dehydrogenating the second heart cut paraffin stream to form a stream comprising olefins.
