Abstract

Spirulina platensis (SP) is aquatic biomass potentially grown as an energy source in the future. Extracting algae oil from SP will leave solid residue called Spirulina platensis residue (SPR). In this study, SPR processed by the pyrolysis process, both catalytic and non-catalytic. This study focused on the effects of different catalysts on the yield of bio-oil obtained from the pyrolysis process. Pyrolysis experiments conducted at a temperature range of 300 – 600oC using three different catalysts: Ni-oxide, Fe-oxide, and silica-alumina, and performed at 550oC in various amounts of 5%-30 wt. % for each catalyst. The effect of temperature on SPR catalytic and non-catalytic pyrolysis was studied. The result shows that the optimum yield of non-catalytic pyrolysis was 27.34 wt.% at 550oC. The yield of bio-oil within catalytic pyrolysis indicates that the maximum pyrolysis oil obtained using Fe-oxide as catalyst with 30.00 wt.% bio-oil, followed with 23.37 wt.% using Ni-oxide catalyst, and 18.41 wt.% using silica-alumina catalyst. The water phase yield for each catalyst was relatively different for every catalyst in various amounts ranging from 5 - 30%. Char and gas yields were almost the same for each type of catalyst in all amount variations. The highest gas yield produced was using the silica-alumina catalyst, followed by Fe-oxide and Ni-oxide catalyst. The SPR catalytic pyrolysis process improves the bio-oil yield with the increasing of the bio-oil yield 2.66 wt.% compared to the SPR non-catalytic pyrolysis.
