Abstract
The present invention relates generally to methods for producing renewable detergent compounds. More specifically, the invention relates to methods for producing detergent intermediates, including bio-linear alkylbenzene (LAB), bio-alcohols, and long chain bio-paraffins, from natural oils.
Claims22
A method for producing an alkylbenzene and a detergent alcohol from a natural oil comprising:
- a) providing a first feed stream comprising natural oil;
- b) deoxygenating said first feed stream to form a stream comprising paraffins;
- c) removing volatile components and gases from said stream comprising paraffins to form a purified paraffin stream;
- d) fractionating said purified paraffin stream into three fractions, wherein a first fraction comprises a lower boiling range, a second fraction comprises a middle boiling range, and a third fraction comprises a high boiling range;
- e) dehydrogenating said first fraction to form a stream comprising olefins;
- f) alkylating said stream comprising olefins with a second feed stream comprising benzene to form a stream comprising alkylbenzenes;
- g) dehydrogenating said second fraction to form a stream comprising olefins and paraffins;
- h) separating said olefins from said paraffins in said stream comprising olefins and paraffins to form an olefin stream;
- i) hydroformylating said olefin stream to form a stream comprising detergent alcohols.
A method for producing an alkylbenzene and a detergent alcohol from a natural oil and kerosene comprising:
- a) providing a first feed stream comprising natural oil;
- b) deoxygenating said first feed stream to form a stream comprising bio-paraffins;
- c) removing volatile components and gases from said stream comprising bio-paraffins to form a purified bio-paraffin stream;
- d) fractionating said purified bio-paraffin stream into three fractions, wherein a first fraction comprises a lower boiling range, a second fraction comprises a middle boiling range, and a third fraction comprises a high boiling range;
- e) providing a second stream comprising kerosene;
- f) hydrotreating said second stream;
- g) sieving said hydrotreated second stream to form a stream comprising kerosene-based paraffin;
- h) combining said first fraction of purified bio-paraffin with said kerosene-based paraffin;
- i) dehydrogenating said combination of said first fraction of purified bio-paraffin and said kerosene-based paraffin to form a stream comprising olefins;
- j) alkylating said stream comprising olefins with a third feed stream comprising benzene to form a stream comprising alkylbenzenes;
- k) dehydrogenating said second fraction of purified bio-paraffin to form a stream comprising olefins and paraffins;
- l) separating said olefins from said paraffins in said stream comprising olefins and paraffins to form an olefin stream;
- m) hydroformylating said olefin stream to form a stream comprising detergent alcohols.
