Abstract

Batubara adalah bahan bakar hidrokarbon padat yang terbentuk dari tumbuhan dan fosil makhluk hidup yang mengalami pengendapan pada tekanan dan suhu tinggi selama jutaan tahun yang lalu. Jenis batubara yang digunakan adalah batubara kualitas rendah (lignit). Batubara kualitas rendah kurang efesien jika digunakan. Untuk mengefisiensikan penggunaan batubara kualitas rendah diperlukan suatu usaha untuk meningkatkan kualitas batubara tersebut. Untuk meningkatkan kualitas batubara dilakukan proses upgrading brown coal. Upgrading brown coal merupakan proses peningkatan nilai kalori batubara. Proses upgrading brown coal dengan pemanfaatan pelumas bekas bertujuan untuk menurunkan kadar air yang terkandung pada batubara sehingga mampu meningkatkan nilai kalori batubara tersebut. Adapun parameter yang dianalisis dalam peningkatan kualitas batubara yaitu nilai kalori dan kadar moisture. Analisis ini dilakukan untuk mengetahui kualitas batubara yang digunakan. Pemanfaatan pelumas bekas dalam meningkatkan kualitas batubara terjadi proses adsorpsi. Hasil pengujian parameter kualitas menunjukkan bahwa sampel batubara dengan penambahan oli 90 ml memiliki kualitas baik dengan nilai kalori 57342 kal/g, dan nilai moisture 11,99 %. Namun, sampel penambahan oli 80 ml dan 90 ml tidak banyak menurunkan nilai moisture, disebabkan pada proses upgrading brown coal pelumas bekas tidak mengisi semua pori pori batubara yang terbuka sehingga sampel batubara masih mengandung sedikit air. Kata kunci : Batubara, batubara tipe lignit, Upgrading, Kalori, Total Moisture
