The byproducts of biomass (slow) pyrolysis are liquid and gas products. The liquid products consist of biooil and biomass vinegar (pyroligneous acid). Biooils can be directly used as fuel with a particular burner, or can also be upgraded to the vehicle fuel. Meanwhile, if used for non-energy products, can be used for the production of green chemical or renewable chemicals such as BioFormaldehyde and wood adhesive. While the aqueous phase of pyrolysis liquid product that is biomass vinegar (pyroligneous acid) can be used for feedstock biophenol production. Previously biomass vinegar has been known for various uses such as latex coagulant, anti-termite and fertilizer. While the biophenol production process scheme of biomass vinegar as follows.
Global consumption for phenol currently reaches 20 million tons or worth 20 billion US dollars (280 trillion rupiah). Renewable phenol or biophenol can substitute phenol which has been produced based on petroleum. Excess heat and excess syngas from the pyrolysis process can be used for the production process of the biophenol as energy sources. An integrated and efficient production unit will produce highly competitive products, such as the pyrolysis process which is primarily charcoal, and from its by-products made derivative products that are desperately needed today.
