Abstract
Isomerization of normal paraffins to form branched paraffins may be complicated by significant cracking of Cparaffins under isomerization reaction conditions. This issue may complicate upgrading of hydrocarbon feeds having significant quantities of heavier normal paraffins. Cracking selectivity may be decreased by combining one or more naphthenic compounds with a feed mixture comprising at least one Cnormal paraffin and/or by utilizing tungstated zirconium catalysts having decreased tungsten loading. Further, Cand Cnormal paraffins may undergo isomerization in the presence of Cnormal paraffins. Methods for isomerizing normal paraffins may comprise: providing a feed mixture comprising at least C-Cnormal paraffins and lacking normal paraffins larger than C; and contacting the feed mixture with a bifunctional mixed metal oxide catalyst under isomerization reaction conditions effective to form a product mixture comprising one or more branched paraffins formed from each of the C-Cnormal paraffins.
