Novel helical screw-fluidized bed reactor for bio-oil production in slow-pyrolysis mode: A preliminary study

Artikel Review: Parameter Operasional Pirolisis Biomassa

“…Namun, pirolisis cepat memiliki keuntungan ekonomi yang lebih baik karena produksi produk bernilai lebih tinggi. Pirolisis lambat secara umum dikenal sebagai cara produksi minyak nabati yang tidak tepat karena menghasilkan cairan yang rendah ± 30% wt (Qureshi et al, 2019).…”

“…Fast pirolisis lebih baik dari pada slow pirolisis karena laju pemanasan yang cepat (>100 0 C/min) dan waktu tinggal gas yang rendah (< 2 s) bergantung pada zona panas (Mohan et al, 2006). Dengan menggunakan cara fast pirolisis mampu menghasilkan biooil diatas 75% wt dari sumber biomassa kayu atau bahan baku yang kering (Qureshi et al, 2019) dan dengan ukuran partikel bahan 2-3 mm (Bridgwater, 2012). Para peneliti juga mencoba untuk memodifikasi desain reaktor untuk meningkatkan jumlah biooil dengan berbagai tipe pengembangan reaktor slow pirolisis.…”

Fast Pyrolysis of Flax Shive in a Screw‐Type Reactor

“…A further improvement in bio-oil yield and quality can be reached when choosing a pyrolysis catalyst or changing the design of the condenser used in the reactor system. Colorado, USA [39] Aston, Great Britain [40] Isfahan, Iran [18,41] Kuala Lumpur, Malaysia [19] Jalan Tungku Link, Brunei [42] Reactor…”

“…Fluidized-bed reactors provide high heat and mass transfer rates leading to a high yield of the value-added products (mostly bio-oil) [9]. In an auger reactor, the solid residence time is longer in comparison with the others, however, it provides a higher stability of the bio-oil obtained [19,23]. A cone reactor requires the use of additional solid heat transfer components (such as sand, aluminosilicates etc.)…”

“…However, the fast pyrolysis results strongly depend on the type of pyrolysis reactor [13][14][15][16][17][18][19][20]. For the fast pyrolysis process, different types of reactors were developed in the past years including fixed bed [13], bubbling fluidized-bed and circulating fluidized-bed reactors [15,20], ablative, auger [19], and rotating reactors etc. The reactor design strongly affects the product yield, heat and mass transfer and allows the solid and volatile residence time to be controlled [21].…”
