Hydrothermal conversion in subcritical water is a conversion technique which is attractive method because of its ability to transform wet biomass into valuable chemicals without drying. In this study, the hydrothermal conversion of xylose was carried out in subcritical water in the absence and in the presence of catalysts. Experiments were performed at temperatures of 250, 300 and 350°C with a reaction time of 1 h. Deep eutectic solvents (DES) were used as catalysts in the hydrothermal conversion of xylose. The effects of temperature and catalyst addition on the yields of gas and liquid products also on gas and liquid composition were examined. DES 1 consisting of potassium carbonate and ethylene glycol, DES 2 composing choline chloride and urea showed catalytic activity by increasing the liquid yield. The main components were identified as hydroxyacetic acid (glycolic acid), lactic acid, 5-hydroxy methyl furfural, furfural and formic acid. The gas product yield was increased by increasing temperature for all samples. The presence of DESs showed catalytic activity on gas yield and the maximum gas yield was obtained as 31.7 % for DES2
