Abstract
Official abstract text for this publication.
Methods of reducing a phosphorus content of a liquid hydrocarbon. The liquid hydrocarbon may be co-fed with an olefin to an alkylation unit to produce a low-phosphorus content liquid hydrocarbon product.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for reducing phosphorus content, the method comprising: contacting a liquid hydrocarbon with an olefin in an alkylation unit, wherein the liquid hydrocarbon comprises a phosphorus containing compound and wherein the liquid hydrocarbon has an initial octane number; alkylating the liquid hydrocarbon and olefin to produce a product having an octane number greater than the initial octane number of the liquid hydrocarbon, wherein the product has a phosphorus content less than about 35 wtppm. 2. The method according to claim 1 wherein the liquid hydrocarbon comprises C5s and C6s. 3. The method according to claim 1 wherein the phosphorus containing compound is a hydrocarbon soluble phosphine. 4. The method according to claim 1 wherein the phosphorus containing compound is a tributyl phosphine. 5. The method according to claim 1 wherein the phosphorus of the phosphorus containing compound transferred to an acid component contained in the alkylation unit. 6. The method according to claim 1 wherein the product has a phosphorus content less than about 20 wtppm. 7. The method according to claim 1 wherein the product has a phosphorus content less than about 15 wtppm. 8. The method according to claim 1 wherein the product has a phosphorus content less than about 10 wtppm.
