Abstract

Bensin (gasoline) merupakan salah satu jenis bahan bakar yang paling banyak dikonsumsi oleh masyarakat dunia, termasuk Indonesia. Produksi minyak mentah terus menerus dilakukan hingga akhirnya cadangan minyak bumi juga semakin habis. Salah satu cara untuk mengatasi permasalahan tersebut adalah dengan memproduksi bahan bakar cair yang berasal dari polimer plastik. Telah dilakukan penelitian dengan tujuan untuk sintesis bahan bakar cair yang berasal dari polimer limbah plastik menggunakan metode konversi katalitik. Katalis yang digunakan adalah material Al-MCM-41 dan limbah plastik polipropilena sebagai reaktan umpan. Variasi pada penelitian ini adalah jumlah katalis Al-MCM-41 sebesar 0%; 3,40%; 6,58%; 9,55% (b/b). Jumlah katalis mampu mempengaruhi produk bahan bakar cair yang dihasilkan. Hasil penelitian menunjukkan bahwa bahan bakar cair yang paling mendekati karakteristik bahan bakar minyak berjenis bensin adalah bahan bakar cair berkatalis 9,55% (b/b) dengan yield fraksi bensin (C7-C12) sebesar 77,18%. Hasil pengujian fisik bahan bakar cair berkatalis 9,55% (b/b) antara lain: densitas 720 kg/m3, titik nyala 68°C, titik didih akhir 235°C, viskositas kinematik 0,504 cSt, kalor pembakaran 11.244 kkal/kg. =============================================================================================== Gasoline is one of the most consumed fuels by the world community. Production of crude oil is continuously carried out until finally oil reserves are getting drained. One way to overcome this problem is to produce liquid fuels derived from plastic polymers. This research has been conducted with the aim of synthesizing liquid fuels derived from plastic waste polymers using catalytic convertion methods. Al-MCM-41 material was used as catalyst for cracking of polypropylene plastic waste as feed reactant. The variation in this study was the amount of Al-MCM-41 catalyst by 0%; 3.40%; 6.58%; 9.55% (w/w). The amount of catalyst affects liquid fuel product. The result of this research shows that fuel produced with 9.55% catalyst (w/w) has 77.18% yield of gasoline fraction (C7-C12) which has closest characteristic with gasoline type of fuel. Physical properties study shows that liquid fuel 9.55% catalyst (w/w) has value of density 720 kg /m3, flash point 68°C, final boiling point 235°C, kinematic viscosity 0.504 cSt, and burning heat 11244 kcal/kg.
