1. A process for preparing a composition comprising aliphatic, olefinic, cyclic and/or aromatic hydrocarbons of five or greater carbon atoms per molecule, said process comprising:
(a) providing a first hydrocarbon mixture comprising isomers of hydrocarbons;
(b) providing a heterogeneous catalyst, the heterogeneous catalyst comprising:
(i) pentasil zeolite in a range between about 1% to about 99% by total weight of the heterogeneous catalyst;
(ii) amorphous silica, amorphous alumina, or a combination thereof, in a range of about 1% to about 99% by total weight of the heterogeneous catalyst;
(iii) Zn and Cu, independently in a range between about 0.05% to about 3% by total weight of the heterogeneous catalyst; and
(iv) rhenium in a range of about 0.05% to about 6% by total weight of the heterogeneous catalyst;
(c) contacting the first hydrocarbon mixture with the heterogeneous catalyst at a temperature increasing from about 300° C. to about 350° C. at rate of about 1° C. per minute; and
(d) forming a second hydrocarbon mixture comprising molecules having five or more carbon atoms, the second hydrocarbon mixture having a higher octane unit and/or a lower vapor pressure as compared to the first hydrocarbon mixture.
