Abstract
Abstract A fuel composition comprising a hydrogenated material obtained by hydrogenating a reaction mixture ranging from C11 to C16 containing mainly compounds which comprise butadiene and cyclopentadiene as basic structural units, produced by reacting an acyclic conjugated diene with cyclopentadiene, dicyclopentadiene, an alkyl-substituted cyclopentadiene, or an alkyl-substituted dicyclopentadiene in accordance with Diels-Alder reaction an isomeric material prepared by isomerizing the hydrogenated material or the mixture of the hydrogenated material and the isomeric material.
