The fast pyrolysis is an efficient and promising process of thermal decomposition. The process consists in the reaction of organic materials in the total or partial absence of oxygen to produce condensable vapor, non-condensable gases and char. Bio-oil is generated after vapor condensation and it can be converted into fuels and/or chemicals. Fast pyrolysis of soy hulls was conducted in a batch reactor fluidized bed, made of stainless steel, with internal diameter of 78 mm and 1069 mm height. The fast pyrolysis of soy hulls, mixed with inert (sand), was carried out at approximately 550 °C. Atmosphere with high nitrogen concentration was used. The present study aimed to investigate the chemical composition of the soy hulls bio-oil using gas chromatography and mass spectrometry techniques.

This study investigates the effect of biomass size on the yields of char, liquid (organic compounds and water) and gas for fast pyrolysis of palm kernel shell (PKS). Fast pyrolysis was carried out in a fluidized bed reactor of 108 mm in internal diameter operated at 450 °C using three different sizes of palm kernel shell (0.325, 0.75 and 1.5 mm). In specific the effect of biomass size on the yields of known and unknown organics in bio-oil was mainly investigated. The major organics include acetic acid, phenol and furfural. The minor ones include 2-methylphenol, 4-methylphenol, 2-methylnaphthalene, benzene, toluene and tetrahydrofurane (THF). Smaller biomass sizes were favorable for higher bio-oil yields.
