The pyrolysis bio-oil which has been studied by many researchers has typically contained a high amount of water, around 20-30%. In this research, the effective bio-oil purification using chemical demulsification method has been studied to reduce the amount of water by breaking down the water-in-oil emulsion on pyrolysis bio-oil. A various dosage of chemical demulsifier (100 ppm, 150 ppm, 200 ppm, and 250 ppm) has been added into the pyrolysis bio-oil and the water separation over time also been

After the injection of 250 ppm of demulsifier at 30 C, the water separation reached a maximum of 72% in 60 minutes and could reduce the water content from 25% to 8.5%. At the temperature of 60 o C and 250 ppm of demulsifier, the water separation reached a maximum of 96% in 35 minutes, and successfully reduced the water content from 25% to 1.3%. Finally, it has been concluded that this bio-crude purification using chemical demulsification method could be applied to effectively reduce the amount of water from pyrolysis bio-oil product. Abstrak (Indonesian) Pyrolysis bio-oil yang telah dipelajari oleh banyak peneliti biasanya mengandung jumlah air yang tinggi, sekitar 20-30% dari kadar air. Sehingga dalam penelitian ini, pemurnian bio-oil yang efektif menggunakan metode demulsifikasi kimia telah dipelajari untuk mengurangi jumlah air dengan memecah emulsi air-dalam-minyak pada pyrolysis bio-oil. Berbagai dosis demulsifier kimia (100 ppm, 150 ppm, 200 ppm, dan 250 ppm) telah ditambahkan ke dalam pirolisis bio-oil dan pemisahan air dari waktu ke waktu juga telah diamati. Dan kemudian suhu bio-oil (30, 40, 50, 60, dan 70 C) juga dipelajari sebagai faktor yang dapat memiliki efek signifikan pada proses demulsifikasi pyrolysis bio-oil. Dari hasil yang diperoleh, setelah injeksi 250 ppm demulsifier pada 30 C, pemisahan air mencapai maksimum 72% dalam 60 menit dan dapat menurunkan kadar air dari 25% menjadi 8,5%. Kemudian pada suhu 60 o C dan 250 ppm demulsifier, pemisahan air mencapai maksimum 96% hanya dalam waktu 35 menit, dan berhasil menurunkan kadar air dari 25% menjadi 1,3%. Akhirnya, telah disimpulkan bahwa pemurnian bio-oil dengan menggunakan metode demulsifikasi kimia dapat diterapkan untuk secara efektif menurunkan kadar air dari pyrolysis bio-oil.
