FIELD: hydrocarbon conversion processes and catalysts.
SUBSTANCE: invention, in particular, relates to selectively upgrading paraffin feedstock via isomerization. Catalyst comprises support and sulfated oxide or hydroxide of at least one of the elements of group IVB deposited thereon; a first component selected from group consisting of consisting of lutetium, ytterbium, thulium, erbium, holmium, and combinations thereof; and a second component comprising at least one platinum-group metal component. Catalyst preparation process comprises sulfating oxide or hydroxide of at least one of the elements of group IVB to form sulfated support; depositing the first component onto prepared support; and further depositing the second component. Invention also relates to hydrocarbon conversion process in presence of above-defined catalyst.
EFFECT: improved catalyst characteristics and stability in naphta isomerization process to increase content of isoparaffins.
