Bio-crude oil production apparatus, system, and method for efficient bio-crude oil production from biomass using fast pyrolysis method

 

 

Client / Market

• Bioenergy-related company

 

Necessity of this Technology

• Bubbling-fluidized-bed system for bio-crude oil production requires a large amount of fluidized gas for sand fluidization, so it needs large size of reactor and pipe with expensive installation cost. Moreover, a lot of undesirable charcoal remains in bio-crude oil because the pyrolysis vapor flows out with bio-char prior to the separation process.

 

Technical Differentiation

• Fast pyrolysis of biomass using this technology does not require the fluidized gas supply, so the facility size is reduced and the installation cost becomes cheaper.
• Fast pyrolysis of biomass using this technology can control heat and mass transfer optimally to maximize the bio-crude oil yield and to produce high quality bio-crude oil with less charcoal.
• Bio-crude oil can be combined to bio-refinery industry, and enable the active coping with certified CO2 emission reduction due to its carbon neutrality.
• This bio-crude oil production system has a simpler structure compared to existing bubbling fluidized bed, circulating fluidized bed reactors, therefore its size and construction cost can be reduced to 2/3 level.
• Pyrolysis-vapor and bio-charcoal are separated during the bio-crude oil production process, and this allows the production of bio-crude oil with high quality.
• It does not use carrier gas which affects the reactor operation condition, which enables an easy plant operation.

 

Excellence of Technology

• Over 10 papers on this technology were published in international journals, and related patents were registered in 7 countries.
• Several delegations from Philippines, Cambodia, Rwanda, and Ghana have visited this plant, and they showed high interests in the utilization of this technology in their countries.
• Performance test in pilot plant of 20 kg/hr showed the bio-crude oil yield of 65% that is comparable to advanced countries. Semi-commercial scale plant of 200 kg/ hr, largest in Korea, is under construction.
• Patents for bio-crude oil manufacturing apparatus, bio-crude oil manufacturing system and method were registered in Korea and abroad (USA, Canada, China, Japan, Germany, Finland, Sweden).
