Abstract

Calcined Petroleum Coke (CPC) salah satu bahan bakar yang banyak didapatkan dari hasil pengolahan minyak bumi terutama untuk sektor industri. Proses desulfurisasi diharapkan dapat menekan unsur sulfur serendah-rendahnya yang dapat menyebabkan banyak kerugian pada sektor industri tersebut. Penelitian ini bertujuan untuk menganalisis pengaruh ukuran butir CaCO3 terhadap kadar sulfur, karbon, dan ikatan molekul dalam CPC. Sampel yang digunakan adalah CPC 200 mesh yang direndam dengan NaOH 3,5 M selama 2 jam, dicampurkan dengan CaCO3 dengan variasi ukuran butir 0,9 mm; 2,24 mm; dan 4,5 mm. Alat yang digunakan adalah reaktor rotary autoclave pada temperatur proses 900°C selama 6 jam. Hasilnya, semakin kecil ukuran butir CaCO3 maka semakin besar kemampuan desulfurisasi pada CPC yaitu hasil tertinggi %S sebesar 0,194% dengan derajat desulfurisasi 45,66%. Kedua, efek penambahan CaCO3 tidak terlalu berpengaruh pada kehadiran karbon. Kadar karbon yang tertinggi pada ukuran butir CaCO3 0,9 mm sebesar 97,026%. Ketiga, temperatur 900°C dan molaritas NaOH 3,5 sudah cukup memutus ikatan kimia sulfur organik. ================================================================================= Calcined Petroleum Coke (CPC)is type of fuel which many found at result of oil refine processing. Desulphurisation process in CPC is aim to decrease the sulphur exist in CPC as low as possible. This research is aim to analyze effect additive substance grain size of CaCO3 to the presence of sulphur, carbon, and molecule bond in CPC. The instrument in this research is rotary autoclave with temperature 900°C during 6 hours. The grain size of CaCO3 as variable used are variation 0,9 mm, 2,24 mm, dan 4,5 mm in each process. The result is the lower grain size of CaCO3, increase the desulphurisation ability. The %S after desulphurisation process is 0,194% with desulphurisation degree 45,66%. Second, effect additive CaCO3 not much influence for presence of carbon. Higher %C at grain size CaCO3 is 97,026%. Third point, temperature 900°C and molarity of NaOH is 3,5 in desulphurisation process is effective to break the chemical bond of organic sulphur in Calcined Petroleum Coke.
