Abstract

The limited fuel reserves must be addressed immediately. One of the biomass that has the potential for renewable energy is microalgae. The advantages of microalgae compared to other biomass is the oil produced, the speed of growth, and does not interfere with food availability. The processing of residual Spirulina platensis microalgae (SPR) by pyrolysis is simple and does not cause pollution. This study's purpose was SPR pyrolysis with a grain size of 140 mesh without and with 5wt.% Fe-oxide catalyst. The variables studied were temperature on the yield of bio-oil products, water phase, charcoal, and gas. Pyrolysis was carried out in a fixed bed reactor at 300, 400, 500, 550, and 600 0C. The higher the pyrolysis temperature, the higher the bio- oil yield, with the optimum catalyst at 400 0C produced 15.34% and without a catalyst at a temperature of 500 0C produced 15.00%. The water yield phase in the range of 300-600 0C is higher for catalyst use (30%-39%) than without catalyst (13.75%-22.25%). The higher the pyrolysis temperature, the lower the yield char. The yield of gas without a catalyst was higher in the range of 30.69%-38.94% compared to catalyst 12.58%-26.18%. At a temperature of 300 0C without a catalyst, the conversion obtained was 48.69%, while with catalyst, 60.08%.
