Abstract

Sustainable Aviation Fuel (SAF) menjadi salah satu solusi strategis dalam mengurangi emisi karbon dari sektor penerbangan yang sulit digantikan oleh elektrifikasi konvensional. Penelitian ini mengkaji pemanfaatan batang pisang sebagai limbah biomassa lignoselulosa yang melimpah untuk diproses menjadi bio-avtur melalui dua tahapan utama, yaitu Hydrothermal Liquefaction (HTL) dan Hydrodeoxygenation (HDO). Proses HTL dilakukan pada rentang suhu 250-350 °C dan tekanan 4-20 MPa untuk menghasilkan bio-crude, kemudian dilanjutkan dengan HDO pada suhu 200-400 °C dengan variasi tekanan 2-10 MPa, rasio hidrogen-air 1:1-4:1, serta penerapan empat jenis katalis heterogen, yaitu CeO2, La2O3, Ga2O3, dan ZnO. Hasil simulasi menggunakan software Aspen Plus menunjukkan bahwa suhu dan rasio hidrogen-air merupakan parameter yang paling berpengaruh terhadap peningkatan yield, sedangkan pengaruh tekanan relatif kecil dalam rentang operasi yang diuji. Hasil terbaik Yield bio-crude didapatkan pada proses HTL ketika suhu dinaikkan dari 250 menjadi 350 °C meningkat dari 59,42% menjadi 62,70%. Pada tahap HDO, didapatkan hasil yield terbaik menggunakan katalis CeO2 pada rasio hidrogen:air adalah 2:1 dan suhu 250 °C di mana terjadi peningkatan signifikan hingga 93,29%, jauh di atas nilai proses tanpa katalis sebesar 75,23%. Analisis komposisi produk menunjukkan pergeseran fraksi hidrokarbon menuju C8-C14, yang merupakan rentang utama komponen bahan bakar jet.

Sustainable Aviation Fuel (SAF) has emerged as a strategic solution to reduce carbon emissions from the aviation sector, which is difficult to decarbonize through conventional electrification. This study investigates the utilization of banana pseudostem as an abundant lignocellulosic biomass waste for bio-aviation fuel production through a two-stage process comprising Hydrothermal Liquefaction (HTL) and Hydrodeoxygenation (HDO). The HTL process was conducted at temperatures ranging from 250-350 °C and pressures of 4-20 MPa to produce bio-crude, followed by HDO at temperatures of 200-400 °C with pressure variations of 2-10 MPa, hydrogen-to-water ratios of 1:1-4:1, and the application of four heterogeneous catalysts, namely CeO2, La2O3, Ga2O3, and ZnO. Simulation results obtained using Aspen Plus indicate that temperature and hydrogen-to-water ratio are the most influential parameters in enhancing product yield, while pressure exhibits a relatively minor effect within the investigated operating range. The highest bio-crude yield in the HTL stage was achieved when the temperature increased from 250 to 350 °C, resulting in an improvement from 59.42% to 62.70%. In the HDO stage, the best yield was obtained using a CeO2 catalyst at a hydrogen-to-water ratio of 2:1 and a temperature of 250 °C, achieving a significant increase to 93.29%, compared to 75.23% for the non-catalytic process. Product composition analysis revealed a shift in hydrocarbon fractions toward the C8-C14 range, which corresponds to the primary components of jet fuel.
