Pyrolysis is a process wherein organic materials are exposed to thermal treatment in the absence of an oxidizing agent, resulting in a solid (char), liquid (tar and bio-oil), and volatile gases (CO, CO2, CH4, and H2). A low temperature, high heating rate, and short gas residence time will favour bio-oil production. Processing conditions can be altered to produce bio-oil at 65-80% of the original feedstock. Bio-oil can be utilized as a primary or secondary fuel source for boilers, heaters, turbines, engines, etc. However, additional research is required to find solutions to the corrosivity and poor storage characteristics of bio-oil. This paper reviews literature pertinent to bio-oil production via pyrolysis. Also, design considerations and conditions for optimization of bio-oil production are investigated.
