(Characteristics of Bio-oil From Gelagah Grass(Linn.)Saccharum spontaneum by Fast Pyrolysis Process

This paper studies the information on production technology of bio-oil from gelagah grass (his paper studies Saccharum spontaneum Linn.) and its properties using fast pyrolysis. The variables used in this study are temperature 550 C and o 600 C and size of samples which are 20, 40 and 60 mesh. The results showed that highest production of bio-oil attained o from sample size 40 mesh with treatment at 550 C, with the following characteristics; yields of liquid was 30 88%, phenol.7.58, pH 2.62, specific gravity 1.1108 g/cm , heating value 25 29 MJ/kg and flame power was at slow level. Bio-oil 3.produced by this process predominantly composed of acetic acid, phenols and dan 1-hydroxy 2-propanone.
