Pyrolysis of Brown Algae (Bifurcaria Bifurcata) in a Stainless Steel Tubular Reactor: From a Review to a Case Study

摘要

This article deals with fast pyrolysis of brown algae, such as Bifurcaria Bifurcata at the range of temperature 300-800 °C in a stainless steel tubular reactor. After a literature review on algae and its importance in renewable sector, a case study was done on pyrolysis of brown algae especially, Bifurcaria Bifurcata. The aim was to experimentally investigate how the temperature, the particle size, the nitrogen flow rate (N_2) and the heating rate affect bio-oil, bio-char and gaseous products. Theseparameters were varied in the ranges of 5-50 °C/min, below 0.2-1 mm and 20-200 mL-min-1, respectively. The maximum bio-oil yield of 41.3wt% was obtained at a pyrolysis temperature of 600 °C, particle size between 0.2-0.5 mm, nitrogen flow rate (N_2) of 100 mL . min~(-1) and heating rate of 5 °C/ min. Liquid product obtained under the most suitable and optimal condition was characterized by elemental analysis, !H-NMR, FT-IR and GC-MS. The analysis of bio-oil showed that bio-oil from Bifurcaria Bifurcata could be a potential source of renewable fuel production and value added chemicals.
