Abstract:
In this paper, the hydrothermal liquefaction of sunflower hulls into biooil and biochar is presented. The main manipulated variables that were studied were biomass load, catalyst type and temperature. The experimental results show that an increase in temperature, increases biooil yield and decreases biochar yield. An increase in biomass load decreases biooil yield. The highest biooil yield was observed when sodium carbonate was used as catalyst. The biooil yield was low in all instances with a maximum oil yield of 4.7 wt% at 340 ºC and 30 wt% biomass load. The biochar yield showed very high yields with a maximum yield of 62 wt% at 280 ºC and 30 wt% biomass load. This study shows that liquefaction of sunflower hulls is a viable option for the production of bio char.
