Phosphorous removal and diene removal, when using diene sensitive catalyst, during conversion of olefins to branched primary alcohols

A process for making a selectively branched alcohol composition, comprising:

• providing a lower olefin feed comprising linear olefins having at least 3 carbon atoms and a concentration of phosphorous-containing compounds;
• contacting said lower olefin feed with a sorbent comprising copper oxide on a support in an amount and under sorbing conditions effective to substantially reduce said concentration of said phosphorous-containing compounds, producing a purified lower olefin feed;
• contacting said purified lower olefin feed with a skeletal isomerization catalyst under isomerization conditions effective to produce selectively branched olefins having up to about 36 carbon atoms, said selectively branched olefins comprising a quantity of dienes;
• reducing said quantity of dienes, thereby producing purified selectively branched olefins;
• and
• converting said purified selectively branched olefins to said selectively branched alcohol composition.

A process for making a selectively branched alcohol composition, comprising:

• providing a lower olefin feed comprising linear olefins having at least 3 carbon atoms and a concentration of phosphorous-containing compounds;
• contacting said lower olefin feed with a sorbent comprising copper oxide on a support in an amount and under conditions effective to substantially reduce said concentration of said phosphorous-containing compounds in said lower olefin feed, producing a purified lower olefin feed;
• contacting said purified lower olefin feed with a skeletal isomerization catalyst under isomerization conditions effective to produce selectively branched olefins having up to about 36 carbon atoms;
• contacting said selectively branched olefins with a hydrogenation catalyst that is sensitive to diene poisoning in the presence of a gas feed comprising an inert gas, said gas feed also comprising from about 2 to about 6 vol. % hydrogen, at a feedstock flow rate of about 1 LHSV or less;
• and
• contacting said selectively branched olefins with a hydroformylation catalyst comprising palladium under hydroformylation conditions, thereby producing said selectively branched alcohol composition.

A process for making a selectively branched primary alcohol composition, comprising:

• contacting a lower olefin feed with an amount of sorbent comprising metal on a support, said metal being selected from the group consisting of Sc, Y, La, Ac, Hf, Unq, V, Nb, Ta, Unp, Cr, Mo.

• contacting said purified lower olefin feed with a skeletal isomerization catalyst under conditions effective to yield skeletally isomerized olefins;
• and
• converting said skeletally isomerized olefins into said selectively branched primary alcohol composition.
