Abstract

Spirulina platensis Residue (SPR) is obtained from the solid residue of Spirulina platensis extraction, which has high carbohydrate and protein content. Pyrolysis technology will convert SPR into a bio-oil, water phase, char, and gas (CO, CO2, H2, CH4) product with the potential as an environmentally friendly and sustainable fuel. This study aims to obtain data on the optimum conditions and product yield composition of SPR catalytic pyrolysis using the in-situ method. Pyrolysis occurs in a fixed-bed reactor with SPR 50 g feed and Fe3O4 catalyst (2.5 g and 5 g) at temperature variations of 300-600 °C with an average heating rate of 14.07 °C/min. The higher the pyrolysis temperature, the more bio-oil yield, the optimum at a temperature of 500 ⁰C. The use of 2.5 and 5 gram catalysts obtained bio-oil yields of
25.01 and 17.67 %. The yield of biochar will be lower with increasing pyrolysis temperature. The optimum condition for the gas production was achieved at 300 °C, using a catalyst of 2.5 and 5 grams, the yield of gas was 23.59, and 19.74 %. Moreover, the smaller the specific gravity and the higher the bio-oils pH, the better it is as a vehicle fuel.
