Abstract
A process for the conversion of linear and/or branched paraffin hydrocarbons based on the use of an ionic liquid catalyst in combination with a metal salt additive, which provides a catalytic composition with an increased activity, compared with said ionic liquid. Under suitable reaction conditions this conversion is leading to paraffin hydrocarbon fraction with higher octane number.
Claims11
A process for isomerization of paraffin hydrocarbon feed in the presence of a composite catalyst containing (a) an ionic liquid catalyst comprised of a N-containing heterocyclic and/or aliphatic organic cation and an inorganic anion derived from metal halides or mixed metal halides, and (b) a metal salt additive selected from the group consisting of (i) at least one metal salt containing a cation of groups 6, 8, 11 or 12 metals, (ii) a mixed metal compound containing at least one cation chosen from group 6, 8, 11 or 12 metals, and (iii) an inorganic or organometallic co-ordination compound containing at least one metal chosen from group 6, 8, 11 or 12 as cationic, neutral or anionic complex.
