Abstract
A method of preparing high linear paraffin or high end-chain monomethyl content products is accomplished by converting synthesis gas in a Fischer-Tropsch reaction to hydrocarbon products. These may be hydrotreated to provide an n-paraffin content of greater than 50% by weight, with substantially all branched paraffins being monomethyl end-chain branched paraffins. At least one non-linear paraffin isomer, which may be a monomethyl paraffin isomer, may be separated from the hydrocarbon products through distillation to provide an n-paraffin product having an n-paraffin content percentage by weight of the n-paraffin product that is greater than the initial n-paraffin content.
Claims20
A Fischer-Tropsch hydrocarbon product comprising n-paraffins in an amount of at least 5% by weight of the hydrocarbon product and branched paraffins, and wherein substantially all of the branched paraffins are monomethyl branched paraffins, and wherein the ratio of end-chain monomethyl branching to internal branching of the monomethyl branched paraffins is at least about 1:1.5.
An alkylaromatic sulfonate product comprising linear alkylaromatic sulfonates in an amount of at least about 5% by weight of product and non-linear alkylaromatic sulfonates, and wherein substantially all the non-linear alkylaromatic sulfonates are monomethyl branched alkylaromtic sulfonates, and wherein the ratio of end-chain monomethyl branching to internal branching of the monomethyl branched paraffins is at least about 1:1.5.
An alkylaromatic hydrocarbon product comprising linear alkylaromatic compounds in an amount of at least about 5% by weight of product and non-linear alkylaromatic compounds, and wherein substantially all the non-linear alkylaromatic compounds are monomethyl-branched alkylaromatic compounds, and wherein the ratio of end-chain monomethyl branching to internal branching of the monomethyl branched alkylaromatic compounds is at least about 1:1.5.
A hydrocarbon product comprising:
- hydrocarbon compounds having a normal boiling point range of from about 150 to 700° F., the hydrocarbon compounds having an initial linear paraffin content of at least about 50% by weight of the hydrocarbon product, a branched paraffin content of less than 20% by weight of hydrocarbon product, and wherein substantially all the branched paraffins are monomethyl branched paraffins, the ratio of end-chain monomethyl branching to internal monomethyl branching of the monomethyl branched paraffins being at least 1:1.
