METHOD FOR HYDROISOMERIZATION TREATMENT OF AROMATIC HYDROCARBON OR AROMATIC HYDROCARBON PRESENT IN HYDROCARBON CONTAINING AROMATIC HYDROCARBON AND CATALYST TO BE USED IN HYDROIOSMERIZATION TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hydroisomerization treatment method for preparing hydrogenated and, isomerized alicyclic hydrocarbons by hydrogenating and isomerizing aromatic hydrocarbons or aromatic hydrocarbons present in hydrocarbons containing the aromatic hydrocarbons, and catalysts to be used in the hydroisomerization treatment method. SOLUTION: A hydrocarbon hydroisomerization treatment method comprises treating hydrocarbons containing aromatic hydrocarbons with hydrogen in the presence of a group VIII metal catalyst supported on a solid acid selected from tungsten zirconia and sulfate group zirconia under pressure to convert the aromatic hydrocarbons into alicyclic hydrocarbons and simultaneously effecting isomerization to prepare alicyclic hydrocarbons.
