Degradation Rate of Brown Macroalgae Sargassum sp. Conversion to Bio-Oil via A Slow Pyrolysis

sp. is a brown macroalgae posing a problem to the marine biota due to eutrophication in the coastline. Therefore, the utilization of Sargassum sp. for bioenergy, especially bio-oil is essential. However, the degradation rate of Sargassum sp. conversion to bio-oil during pyrolysis has yet to be examined. Hence, the purpose of this work is to examine the degradation rate of Sargassum sp. conversion to bio-oil during pyrolysis. Slow pyrolysis was performed using a batch reaction vessel under varied temperatures (400-600 & DEG;C) and reaction times (10-50 min). The activation energy as well as the pre exponential factor were determined by assuming a first-order reaction and employing the Arrhenius equation. The activation energy of 15.27 kJ mol-1 and pre-exponential factor of 0.477 s-1 were determined for the degradation of Sargassum sp. during pyrolysis.
