The Comparison of Bio-oil Production from Sugarcane Trash, Napier Grass, and Rubber Tree in The Circulating Fluidized Bed Reactor

Abstract

This experiment is to compare the bio-oil production from sugarcane trash, napier grass, and rubber tree. Three of biomass were used in this experiment. The feed rate of biomass at 45 kg/h, 60 kg/h, and 75 kg/h was installed in the fast pyrolysis process, the temperature ranging from 440 ^oC to 520 ^oC and the superficial velocity of 7 m/s. The influence on temperature, bio-oil properties, cold efficiency and energy conversion were studied. The result indicated that the sugarcane trash is the best condition to produce the bio-oil yield and is higher than that of napier grass and rubber tree. The bio-oil yield from sugarcane trash was 49.47

wt% while the bio-oil yield from Napier grass and rubber tree were 43.73 wt% and 26.33 wt%, respectively. the properties of bio-oil include Oxygen, carbon, hydrogen, and nitrogen in which the best properties are sugarcane trash with percentage of 52.185%, 37.573%, 9.653% and 0.589%, respectively. The heating value (HHV) of sugarcane trash was 16.417 MJ/kg while High Heating Value (HHV) of Napier grass and rubber tree were 11.088 MJ/kg and 8.288 MJ/kg, respectively. The sugarcane trash was able to producing the cold efficiency and energy conversion at33.33% and 26.48%, respectively.
