Hydrocarbon conversion processes using lactamium-based ionic liquids

A hydrocarbon conversion process comprising:

• contacting a hydrocarbon feed with a lactamium based ionic liquid catalyst in a hydrocarbon conversion zone under hydrocarbon conversion conditions to form a mixture comprising conversion reaction products, and the lactamium based ionic liquid catalyst, wherein the hydrocarbon conversion processes comprises at least one of alkylation, oligomerization, isomerization, disproportionation, and reverse disproportionation;
• separating the conversion reaction products from the lactamium based ionic liquid catalyst;
• recovering the conversion reaction products;
• and
• recycling the lactamium based ionic liquid to the reaction zone;
• wherein the lactamium based ionic liquid catalyst comprises at least one of:
• a reaction product of a lactam compound having a general formula
• wherein R is hydrogen, an alkyl group having from 1 to 12 carbon atoms, an amine, an ether, or a silyl group, n is 1 to 8;
• and a Brønsted acid HX;
• or a Brønsted acid HX, where X is a halide, and a metal halide;
• or
• a reaction product of a lactam compound having a general formula
• wherein the ring has at least one C≡C double bond, R is hydrogen, an alkyl group having from 1 to 12 carbon atoms, an amine, an ether, or a silyl group, n is 1 to 8;
• and a Brønsted acid HX;
• or a Brønsted acid HX, where X is a halide, and a metal halide;
• or
• a reaction product of a lactam compound having a general formula
• wherein R is hydrogen, an alkyl group having from 1 to 12 carbon atoms, an amine, an ether, or a silyl group, n is 1 to 8, m is 1 to 8, and the rings can be saturated or unsaturated;
• and a Brønsted acid HX;
• or a Brønsted acid HX, where X is a halide, and a metal halide.
