PYROLYSIS OIL

Pyrolysis Oil or "bio-oil" is a product of anaerobic ("destructive") distillation of biomass. Upon heating of wood or other biomass to sufficient temperature in an air-tight chamber, volatile components are produced. After cooling, some of these are gaseous (hydrogen, carbon monoxide) while others are in liquid form, the so-called pyrolysis oil. This oil is a dense fuel source - for applications such as heating and steam production. It may be burned by a burner such as the Babington burner. As such, this is a lower-tech substitute for petroleum fuels in some applications, with lower caloric value than diesel fuel. At present, it cannot be substituted for diesel in internal-combustion engines due to high viscosity and acidity. Upgrading of bio-oil to Diesel fuel via the Fischer-Tropsch process is possible but may not be practical. Recently, a cheap and open source way to upgrade bio-oil via Red Mud was discovered.

 

Energy from pyrolysis oil

Pyrolysis oil can be used in several applications to produce heat, electricity and cooling.

The physical properties include viscosity, heating value, density, water content, oxygen content, pH value, density and solid contents etc., whereas the identification of various chemical compounds present in the bio-oil, various functional group and their chemical bonding etc. are included in the chemical properties.

A review of the physical properties of different types of pyrolysis oil at various conditions has been made and some probable solutions are suggested based on Viscosity,Heating Value,Oxygen Content,Acidity / pH Value, and Density.
