Abstract
A reaction system and method for removing heteroatoms from oxidized-heteroatom-containing hydrocarbon streams and products derived therefrom are disclosed. An oxidized-heteroatom-containing hydrocarbon feed is reacted in a reaction system thereby forming non-ionic hydrocarbon products. The products derived therefrom are useful as transportation fuels, lubricants, refinery intermediates, or refinery feeds.
Claims14
A reaction method for reducing the heteroatom content, reducing total acid number, and increasing API gravity of oxidized-heteroatom-containing hydrocarbon feed streams comprising:
- providing oxidized-heteroatom-containing hydrocarbon feed streams through a feed inlet region;
- providing a contact region, the contact region having at least one caustic and a selectivity promoter operatively positioned therein;
- contacting the oxidized-heteroatom-containing hydrocarbon feed streams in the contact region thereby producing substantially non-ionic hydrocarbon products having a heteroatom content less than the oxidized-heteroatom-containing hydrocarbon feed streams that entered through the inlet region;
- and
- removing the substantially non-ionic hydrocarbon products having a heteroatom content less than the oxidized-heteroatom-containing hydrocarbon feed streams that entered through the inlet region from the contact region to an outlet region;
- wherein the caustic component of the contact region comprises:
- inorganic compounds that exhibit basic properties;
- inorganic oxides from group IA and IIA elements;
- and
- mixtures of oxides and hydroxides of group IA and IIA elements;
- wherein the selectivity promoter comprises:
- an organic alcohol, ROH, wherein R is a C1-C18 alkyl-, aryl-, or alkenyl-group, that produces a substantially non-ionized hydrocarbon product.
A reaction method for reducing the heteroatom content, reducing total acid number, and increasing API gravity of oxidized-heteroatom-containing hydrocarbon feed streams comprising:
- providing oxidized-heteroatom-containing hydrocarbon feed streams through a feed inlet region;
- providing a contact region, the contact region having a molten mixture of sodium hydroxide, potassium hydroxide and a selectivity promoter operatively positioned therein;
- contacting the oxidized-heteroatom-containing hydrocarbon feed streams in the contact region thereby producing substantially non-ionic hydrocarbon products having a heteroatom content less than the oxidized-heteroatom-containing hydrocarbon feed streams that entered through the inlet region;
- and reducing total acid number, and increasing API gravity;
- and
- removing the substantially non-ionic hydrocarbon products through an outlet region;
- wherein the selectivity promoter comprises:
- an organic alcohol, ROH, wherein R is a C1-C18 alkyl-, aryl-, or alkenyl-group, that produces a substantially non-ionized hydrocarbon product.
