Pyrolysis oil sometimes also known as biocrude or biooil, is a synthetic fuel under investigation as substitute for petroleum. It is extracted by biomass to liquid technology of destructive distillation from dried biomass in a reactor at temperature of about 500°C with subsequent cooling. Pyrolytic oil (or bio-oil) is a kind of tar and normally contains too high levels of oxygen to be a hydrocarbon. As such it is distinctly different from similar petroleum products.
There have been few standards efforts so far for pyrolysis oil; one of the few is from ASTM.
