Abstract
Bahan bakar cair telah berhasil didapatkan menggunakan metode perengkahan katalitik. Penelitian ini dilakukan pada limbah plastik polistirena (PS) menggunakan dan tanpa katalis Al-MCM-41/Keramik untuk menghasilkan fraksi hidrokarbon. Efek dari katalis, waktu perengkahan katalitik, dan penambahan ko-reaktan biodiesel minyak jelantah pada hasil dan fraksi hidrokarbon telah diteliti. Katalis yang digunakan dikarakterisasi menggunakan XRD, SEM, Adsorpsi-desorpsi N2, FTIR-Piridin, dan hasil perengkahan dianalisa menggunakan Kromatografi Gas-Spektroskopi Massa (KG-SM). Hasil analisa GC-MS menunjukkan bahwa komponen kimia hasil perengkahan PS, PS/Kat60, dan PS/Kat120 tersusun dari hidrokarbon aromatik. Komponen senyawa hidrokarbon aromatik maksimum mencapai 99,87% pada PS/Kat120. Komponen kimia untuk perengkahan katalitik PS/BMJ/Kat60 dan PS/BMJ/Kat120 terdapat senyawa metil ester. Senyawa metil ester PS/BMJ/Kat60 sebesar 47,42%, menurun pada PS/BMJ/Kat120 menjadi 39,31% serta terbentuk hidrokarbon alifatik sebesar 22,16%. Campuran bahan bakar cair jenis CPS/Kat memiliki efisiensi termal tertinggi sebesar 26,49%, dengan karakteristik nilai densitas 0,7405 g/cm3, viskositas 0,3436 cSt, titik nyala -49,4 oC, dan nilai kalor 9743,87 kkal/kg.

Liquid fuel has been obtained successfully by cracking method. This research was carried out on polystyrene plastic waste (PS) with and without Al-MCM-41/Ceramics catalyst to produce hydrocarbon fractions. The effect of the catalyst, time of catalytic cracking, and waste cooking oil biodiesel on the results and properties of hydrocarbons have been investigated. The catalyst used were characterized by XRD, SEM, Adsorption-desorption N2, FTIR-Pyridine, and cracking result were analyzed using Gas Chromatography-Mass Spectroscopy (GC-MS). The GC-MS analysis results showed that the chemical component of PS, PS/Kat60, and PS/Kat120 are composed aromatic hydrocarbons. The maximum component of aromatic hydrocarbon compunds reaches 99.87% in PS/Kat120. The pyrolysis of PS/BMJ/Kat60 and PS/BMJ/Kat120 produce a methyl ester compound. Methyl ester compound of PS/BMJ/Kat60 reached 47.42%, decreased in PS/BMJ/Kat120 to 39.31% and aliphatic hydrocarbons formed by 22.16%. The performance of a mixture of liquid fuel CPS/Kat has the highest thermal efficiency of 26.49%, with a density value of 0.7405 g/cm3, flash point -49.4oC, viscosity of 0.3436 cSt, and calorific value of 9743.87 kcal/kg.
