This paper presents research results regarding acid hydrolysis of Acacia mangium wood sawdust forming xylose for further production of furfural. The optimization of the hydrolysis process in a hydrolyzer and pilot scale was studied. Optimal conditions of the hydrolysis were established as follows: temperature was increased from 100 to 140 o C within approx. 35 min, retention time at the maximum temperature was 25‐50 minutes, sulfuric acid concentration of 0.75 %, solid‐to‐liquor ratio of 1:8. Under these conditions, xylose yield was 7.59 % over the oven dried amount of the wood sawdust used. The glucose (0.93 % w/w) and furfural (0.33 % w/w) were obtained as by‐products of the hydrolysis process. The furfural synthesis from the obtained xylose was successfully carried out.
