Abstract
Bahan bakar cair dari limbah plastik polistiren (PS) dengan ko-reaktan biodiesel minyak jelantah telah berhasil dibuat. Penelitian ini dilakukan dengan metode perengkahan katalitik menggunakan katalis untuk menghasilkan berbagai macam fraksi hidrokarbon. Katalis yang digunakan berupa Pd/Al-MCM-41/keramik yang dikarakterisasi dengan XRD, SEM-EDX, SEM, Adsorpsi-desorpsi N2, FTIR-Piridin, dan hasil perengkahan dianalisa menggunakan Kromatografi Gas-Spektroskopi Massa (GC-MS). Hasil analisis GC-MS bahan bakar hasil perengkahan menunjukkan bahwa kandungan terbesar pada fraksi hidrokarbon gasolin (C7-C12). Minyak perengkahan PS/Kat120 memiliki fraksi gasolin terbesar yaitu 85,64 %. Bahan bakar cair hasil perengkahan katalitik ditambahkan bahan bakar jenis Premium dan aditif MTBE untuk mengetahui performa bahan bakar menggunakan mesin gasolin. Karakteristik fisik berupa densitas, titik nyala, nilai kalor, dan angka oktan campuran bahan bakar cair juga diteliti. Campuran bahan bakar cair CPSJ/Kat2 memiliki persen efesiensi termal tertinggi sebesar 26,33% dengan nilai densitas 0,7515 g/ml, titik nyala sebesar -48,7 ℃, nilai kalor sebesar 19160,61 kkal/kg, dan angka oktan sebesar 95,6.

Liquid fuel from polystyrene (PS) waste plastic and the co-reactant of waste cooking oil has been successfully made. This research was carried out using a catalytic cracking method using a catalyst to produce various kinds of hydrocarbon fractions. The catalysts used were Pd/Al-MCM-41-ceramics characterized by XRD, SEM-EDX, SEM, Adsorption-desorption N2, FTIR-Piridine, and cracking results analyzed using Gas Chromatography-Mass Spectroscopy (GC-MS). The results of GC-MS analysis of cracked fuel showed that the largest content of the gasoline hydrocarbon fraction (C7-C12). PS/Kat120 cracking oil has the largest gasoline fraction of 85.64%. Liquid fuel produced by catalytic cracking is added with Premium fuel and MTBE additives to determine fuel performance using gasoline engines. Physical characteristics in the form of density, flash point, calorific value, and octane number of a mixture of liquid fuels were also investigated. The mixture of CPSJ / Kat2 liquid fuel has the highest percentage of thermal efficiency of 26.33% with a density value of 0.7515 g / ml, a flash point of -48.7 ℃, a heating value of 19160.61 kcal / kg, and an octane number of 95.6.
