Abstract

Penelitian ini bertujuan untuk memperoleh senyawa aromatik pada bahan bakar cair yang terbuat dari limbah minyak WCO (Waste Cooking Oil) dan Limbah Plastik PET ( Polyetylene Terephthalate) dibantu dengan katalis alumina silika Al-MCM-41 dengan metode pirolisis perengkahan katalitik dan dilanjutkan dengan hidrotermal tekanan rendah. Sebelum digunakan katalis Al-MCM-41 di karakterisasi dengan XRD, Uji Adsorpsi-Desorpsi Nitrogen, dan FTIR. Proses diawali dengan pemurnian minyak jelantah (WCO) dengan metode degumming yaitu pemurnian minyak dari sisa gum di dalamnya. Lalu minyak tersebut digunakan untuk proses pirolisis perengkahan katalitik bersama limbah PET yang telah dipotong-potong kecil dengan perbandingan WCO:PET 1:1 yang ditambahkan katalis Al-MCM-41. Proses tersebut dilakukan pada suhu 450o C selama 2 jam dan didapatkan hasil sebanyak 67,28 gram dari massa total 100 gram. Hasil minyak dari proses tersebut kemudian kembali digunakan untuk proses hidrotermal tekanan rendah. Proses hidrotermal tekanan rendah ini menggunakan 2 variasi. Pirolisis yang pertama dengan variasi perbandingan WCO-PET:Toluena 1:1 dihasilkan produk sebanyak 6,62 gram dari massa total 15 gram, sedangkan variasi selanjutnya yaitu WCO-PET:Toluena 2:1 dan didapatkan produk sebanyak 1,98 gram dari massa total 15 gram. Kemudian sampel hasil dari pirolisis perengkahan katalitik dan hidrotermal tekanan rendah dikarakterisasi GC-MS. Diperoleh hasil bahwa sampel minyak tersebut terdapat senyawa aromatik dan alifatik di dalamnya. Pada sampel pirolisis didapatkan senyawa aromatik dan alifatik sebanyak 60,93% dan 34,09% serta terdapat kandungan nitril sebanyak 4,98%. Pada sampel hidrotermal dengan perbandingan WCO-PET:Toluena 1:1 diperoleh senyawa aromatik dan alifatik sebanyak 60,59% dan 39,41%. Untuk perbandingan WCO-PET:Toluena 2:1 didapatkan senyawa aromatik dan alifatik sebanyak 61,24% dan 38,76%.

This study aims to obtain aromatic compounds in liquid fuels made from waste cooking oil (WCO) and PET plastic waste (Polyethylene Terephthalate) assisted by alumina silica catalyst Al-MCM-41 using catalytic cracking pyrolysis and continued with low pressure hydrothermal. Before being used, the Al-MCM-41 catalyst was characterized using XRD, Nitrogen Adsorption-Desorption Test, and FTIR. The process begins with the purification of used cooking oil (WCO) using the degumming method, namely the purification of oil from the remaining gum in it. Then the oil is used for the catalytic cracking pyrolysis process with PET waste that has been cut into small pieces with a WCO:PET ratio of 1:1 and using the Al-MCM-41 catalyst. The process was carried out at a temperature of 450o C for 2 hours and obtained a result of 67.28 grams from a total mass of 100 grams. The oil results from the process were then used again for the low pressure hydrothermal process. This low pressure hydrothermal process uses 2 variations. First with a variation of the WCO-PET: Toluene ratio of 1: 1, the product produced was 6.62 grams from a total mass of 15 grams. While the next variation is WCO-PET: Toluene 2: 1 and the product obtained was 1.98 grams from a total mass of 15 grams. Then the sample results from catalytic cracking and low pressure hydrothermal pyrolysis were characterized by GC-MS. The results showed that the oil sample contained aromatic and aliphatic compounds in it. In the pyrolysis sample, aromatic and aliphatic compounds were obtained as much as 60.93% and 34.09% and there was a nitrile content of 4.98%. In the hydrothermal sample with a WCO-PET: Toluene ratio of 1: 1, aromatic and aliphatic compounds were obtained as much as 60.59% and 39.41%. For the comparison of WCO-PET:Toluene 2:1, aromatic and aliphatic compounds were obtained as much as 61.24% and 38.76%.
