1. the method utilizing the amylene in fischer-tropsch reaction product to produce 2,6-dimethylnaphthalene, comprises Fischer-Tropsch amylene separating unit, alkylation, dehydrocyclization unit, isomerization unit, 2,6-dimethylnaphthalene separating unit;

  • Described method comprises following step successively;

    A) Fischer-Tropsch product enters Fischer-Tropsch amylene separating unit, by the amylene in product and other product separation out;

    B) above-mentioned alkene, in alkylation, with toluene generation alkylated reaction, generates containing C 12the polyalkylbenzene of component;

    C) containing C 12the polyalkylbenzene of component enters dehydrocyclization unit, changes the mixture containing 2,6-dimethylnaphthalene into;

    D) mixture described in enters 2,6-dimethylnaphthalene separating unit, is separated by 2,6-dimethylnaphthalene;

    E), after 2,6-dimethylnaphthalenes are separated, other dimethylnaphthalene isomers in dehydrocyclization product, through isomerization unit, isomery turns to the mixture containing 2,6-dimethylnaphthalene, reenters 2,6-dimethylnaphthalene separating unit.
