A method for making a fuel includes reacting a conjugated diene or a mixture of conjugated dienes with a catalyst selected from the group consisting of a low valent iron catalyst stabilized with a pyridineimine ligand, an iron precatalyst coordinated to the pyridineimine ligand that is activated with a reducing agent, a low oxidation state Fe complex stabilized with a pyridineimine ligand and a coordinating ligand, and combinations thereof, thereby forming a substituted cyclooctadiene. The substituted cyclooctadiene is then hydrogenated, thereby forming cyclooctane fuel.

A metal complex represented by the following Formula (1): ##STR00001##
(wherein M represents palladium or platinum; L represents a ligand selected from carbon monoxide, an olefin compound, an amine compound, a phosphine compound, an N-heterocyclic carbene compound, a nitrile compound and an isocyanide compound; n represents an integer of 0 to 2 showing the number of the ligand; and each of R.sup.1 to R.sup.4 represents an organic group). The metal complex described above can be fixed on an inorganic oxide while maintaining a skeletal structure thereof to obtain a supported metal complex, and this makes it possible to allow the supported metal complex to maintain the same catalytic activity as that of the original metal complex. Also, calcining the supported metal complex obtained in the manner described above makes it possible to obtain a supported metal catalyst which is improved in catalytic activity to a greater extent than conventional supported metal catalysts.

An olefin conversion catalyst and its preparation method and application are disclosed. The catalyst comprises the following components, in parts by mass: a) 50-90 parts of a molecular sieve with a structure of twelve-membered ring and above; b) calculated as oxide, 0.1-10 parts of an added component selected from Group IA metal elements, Group IIA metal elements, or a combination thereof; c) calculated as oxide, 0.1-10 parts of a modifying component selected from silicon, germanium, bismuth, tin, boron, gallium or a combination thereof; and d) 10-49 parts of a support component. When the catalyst is used to convert a small amount of olefins in an aromatic distillate oil, it has the characteristics of high activity and stability, long life and effective utilization of olefins.
