Outline of Final Research Achievements	Biomass is bulky and hard to transport. It is essential to convert biomass into more valuable chemicals on-site. One option is pyrolysis but it has demerit to produce inactive high molecular weight tar. We improved selectivity of sugar-derived tar by thermal decomposition of cedar tree under 300 degree Celsius. And addition of calcium compounds brought about 60% contents of dehydrated sugars in cellulose tar. Levoglucosan for standard pyrolyzate of cellulose was hydrolized under hydrothermal condition at 200 degree Celsius, more valuable dehydrated sugar HMF contents became higher than unreacted one.
