Abstract

Tujuan penelitian ini adalah mempelajari pengaruh karakteristik batubara terhadap proses pencairan dengan menggunakan metoda hidrogenasi katalitik. Sampel batubara yang digunakan adalah batubara Sorong dengan peringkat lignit dan batubara Mulia dengan peringkat sub bituminus. Proses pencairan dilakukan dalam sebuah otoklaf yang berkapasitas 5 liter dengan menggunakan pelarut antrasen dan katalis bijih besi. Kisaran suhu pencairan adalah 375ºC, 400ºC, 425ºC, dan 450ºC, sementara tekanan awal hidrogen ditetapkan 100 bar. Hasil yang diperoleh menunjukan bahwa karakteristik batubara memiliki pengaruh yang signifikan terhadap pencairan. Konversi tertinggi batubara Sorong adalah 89,94% pada suhu 400ºC, sementara untuk batubara Mulia sebesar 87,28% pada suhu 450ºC
