Production of upgraded wood pellet (Hyper wood pellet) from torrefied wood chips and pellets were evaluated under various conditions. In laboratory scale production, heat treatment using an inert gas oven was investigated to Japanese cedar (Cryptomeria japonica) and oak (Konara, Quercus serrata). As the result, calorific values were improved in both species: the upgrade ratio of HHV in Japanese cedar was nearly 30% by the heat treatment at 240 ℃. We also investigated the other three heat treatments using reduced pressure, superheated steam, and conventional charcoal ovens considering larger scale production. In the conventional charcoal oven, Hyper wood pellets with 25MJ/kg of calorific value were produced by the heat treatment at 350℃.
