Abstract
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.
Claims8
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.
