High-density fuel oil

摘要

The present invention provided a high-density fuel oil comprising an isomerized product prepared by isomerizing an alicyclic saturated hydrocarbon represented by the following formula in the presence of an acid catalyst: <IMAGE> wherein each of m and n is 0 or 1, and each of R1 to R3 is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, but the number of the total carbons of R1 to R3 is within the range of 1 to 3.
