Stable product oligomer selectivity from olefin oligomerization on ZSM-5 zeolites and zeotypes

A method for converting alkenes to higher liquid products, comprising:

• combining a source of quaternary ammonium surfactant with hydrocarbon chains, a source of sodium, and water to form an aqueous solution, wherein the source of the quaternary ammonium surfactant with hydrocarbon chains is represented by:
• CnH2n+1—N+(CH3)2—C6H12—N+(CH3)2—CnH2n+1, where n is 4 to 8;
• homogenizing the aqueous solution;
• adding a source of aluminum to the homogenized aqueous solution to form an intermediate agent;
• homogenizing the intermediate agent to form an aluminum-containing intermediate agent;
• adding a source of silicon to the aluminum-containing intermediate agent to form an aluminosilicate-containing intermediate agent, wherein a ratio of the quaternary ammonium surfactant with hydrocarbon chains to silicon is 0.05 to 0.20;
• homogenizing the aluminosilicate-containing intermediate agent to form a synthesis gel;
• crystallizing the synthesis gel to form a MFI zeolite;
• contacting one or more alkenes having 2 to 12 carbon atoms with the MFI zeolite comprising a silicon to aluminum ratio (Si:Al) of about 10 to about 100 and a crystallite size of about 0.001 μm to about 0.1 μm;
• and
• oligomerizing the one or more alkenes in the presence of the MFI zeolite to form an oligomer having 4 to 26 carbon atoms.
