Abstract

Indonesia adalah suatu negara dengan sumber daya alam yang melimpah, seperti mineral tambang dan minyak bumi. Pada pengolahan minyak bumi,Minyak bumi dapat diolah untuk dijadikan sumber energi bahan bakar seperti bensin, solar, oil, petroleum coke, dan lain-lain. Salah satu potensi minyak bumi di Indonesia adalah petroleum coke. Petroleum coke merupakan produk yang dihasilkan selama proses penyulingan minyak (oil refining).Proses pengurangan kadar sulfur pada kokas petroleum yang terkalsinasi dapat dilakukan dengan proses desulfurisasi . Industri – industri yang mempunyai potensial menjadi konsumen dari pengolahan petroleum coke adalah industri peleburan aluminium (anoda, blok grafit, mortar karbon), industri peleburan besi dan baja (carbon riser), industri baterai kering (calcined coke), industri pengecoran logam (foundry coke), dan sebagainya.Proses pengurangan kadar sulfur pada calcined petroleum coke dapat dilakukan dengan proses desulfurisasi termal dengan senyawal alkali NaOH. Desulfurisasi petroleum coke bisa dilakukan dengan dua cara, yaitu desulfurisasi termal dan hidrodesulfurisasi. Penelitian ini bertujuan untuk mengetahui pengaruh variasi ukuran butir terhadap kadar sulfur, kadar karbon, dan ikatan kimia dalam calcined petroleum coke. Bahan baku yang digunakan adalah calcined petroleum coke dengan kadar sulfur sebanyak 0,653%. Ukuran butir yang digunakan adalah 50 mesh, kemudian divariasikan menjadi 20 mesh dan 100 mesh untuk setiap proses desulfurisasi. Hasil desulfurisasi diuji dengan ICP, UV-VIS, dan FTIR untuk mengetahui kadar unsur sulfur, karbon, ikatan kimia dan kandungan sulfur yang terlarut pada air sisa proses pencucian yang terkandung dalam calcined petroleum coke. Dari beberapa variasi ukuran butir yang disebutkan, nilai yang optimal terdapat pada variasi ukuran butir 100 mesh, dimana kadar sulfur dalam petroleum coke adalah 0,24% dan kadar karbonnya mencapai kadar tertinggi yaitu 97,8%. Sedangkan untuk ukuran butir 100 mesh dalam proses desulfurisasi sudah cukup untuk memutus ikatan kimia sulfur organik dalam petroleum coke. ======================================================================================================================= Indonesia is a country with abundant natural resources, such as minerals and petroleum. On the processing of petroleum, petroleum oil can be processed to be used as an energy source of fuel such as gasoline, diesel fuel, oil, petroleum coke, and others. One of the petroleum potential in Indonesia is petroleum coke. Petroleum coke is a product that is produced during the refining process of oil (oil refining) . Reduction process in the sulfur content of calcined petroleum coke which can be done with the desulfurization process. Industries that have the potential to be consumers of processing of petroleum coke is the aluminum smelting industry (anode, graphite blocks, mortar carbon), industrial smelting iron and steel (carbon riser), the battery industry dried (calcined coke), the metal casting industry (foundry coke ), and others lain.Reduction process of sulfur content in calcined petroleum coke can be done with thermal desulfurization process with senyawal alkaline NaOH. Desulfurization of petroleum coke can be done in two ways, namely thermal desulfurization and hydrodesulfurization. This study aims to determine the effect of variations in the particle size of the sulfur, carbon content, and the chemical bonds in the calcined petroleum coke. The raw materials used are calcined petroleum coke with a sulfur content of as much as 0.653%. The grain size used was 50 mesh, then varied to 20 mesh and 100 mesh for each desulfurization process. Desulfurization results were tested by ICP, UV-VIS and FTIR to determine levels of elemental sulfur, carbon, chemical bonds and sulfur dissolved in the residual water contained in the washing process calcined petroleum coke. From some variation in particle size mentioned, there is an optimal value on the variation of the particle size of 100 mesh, where the levels of sulfur in petroleum coke was 0.24% and the carbon content reaches the highest level of 97.8%. As for the particle size of 100 mesh in the desulfurization process is sufficient to break the chemical bonds in the organic sulfur calcined petroleum coke.
