Abstract

Pemanfaatan biomassa untuk mengurangi ketergantungan terhadap bahan bakar fosil dapat dilakukan melalui teknologi pembriketan. Kualitas briket dipengaruhi oleh beberapa faktor, salah satunya adalah ukuran partikel serbuk arang. Serbuk gergaji dan limbah tempurung kelapa merupakan sumber biomassa yang menjanjikan. Kajian yang dilakukan bertujuan untuk mengetahui pengaruh variasi ukuran partikel serbuk arang terhadap karakteristik briket yang meliputi kadar air dan kadar abu. Kajian menggunakan ukuran partikel serbuk arang 10 mesh, 20 mesh, dan 40 mesh. Hasil pengujian menunjukkan bahwa briket arang yang dihasilkan memiliki rata-rata kadar air 5,571% dan rata-rata kadar abu 1,994% pada ukuran partikel 10 mesh. Pada ukuran partikel 20 mesh menghasilkan briket dengan rata-rata kadar air 5,598% dan rata-rata kadar abu 2,573%. Sedangkan pada ukuran partikel 40 mesh menghasilkan briket dengan rata-rata kadar air 5,461% dan rata-rata kadar abu 4,762%. Ukuran partikel serbuk arang tidak berpengaruh terlalu signifikan terhadap kadar air, tetapi memiliki pengaruh signifikan terhadap kadar abu. Hal ini dapat dilihat dari kenaikan kadar abu hingga mencapai 0,5-2% untuk masing-masing variasi ukuran partikel serbuk arang.

Abstract

In the modern era, the high energy consumption associated with technological advancements poses a potential energy crisis due to the finite nature of fossil fuel resources. One explored solution is the utilization of renewable energy through biomass conversion. This study aims to convert pine flower waste into bio-oil via pyrolysis with the assistance of Mo/clay catalysts, to investigate the effect of Mo/clay catalyst addition on the resulting bio-oil yield, and to analyze the physical characteristics of the pyrolyzed pine flower waste bio-oil in comparison with conventional diesel fuel. Various catalyst concentrations 0% (without catalyst), 7%, 9%, and 11% with Mo loading of 1% of the catalyst mass, were employed. Pyrolysis was conducted at a temperature of 320°C for 120 minutes under oxygen-free conditions, followed by distillation to remove water content from the bio-oil. The results of the study demonstrate that the addition of Mo/clay catalyst positively influences the bio-oil yield and its physical characteristics. The optimal results were achieved at a catalyst concentration of 9%, resulting in a density of 1.008 g/ml, viscosity of 49.603 cSt, and calorific value of 8,266.4981 cal/g. However, the pine flower waste-derived bio-oil has yet to be directly employed as a substitute for conventional diesel fuel.
