Abstract—The catalysis of Japanese cedar pyrolysis by 13X or 4Å molecular sieves at low temperatures has been investigated. Japanese cedar was placed in a glass reactor and heated to 450°C under a nitrogen atmosphere to promote thermal decomposition. The flammable gas component, condensed wood vinegar, soluble gas component, and residue were examined. The gases detected included CH4, C3H6, C3H8, and CO2. The amount of combustible gases generated increased when thermal decomposition was undertaken with the addition of 13X molecular sieves. Moreover, tar was not generated when 13X molecular sieves were added.
