Abstract
Bahan bakar cair dari limbah polistirena dan biodiesel minyak jelantah telah berhasil diperoleh melalui perengkahan katalitik menggunakan katalis Al-MCM-41/Keramik. Struktur, morfologi, keasaman, dan porositas katalis dipelajari dengan XRD, SEM-EDX, FTIR Piridin, dan adsorpsi-desorpsi gas N2. Produk perengkahan katalitik dianalisis menggunakan kromatografi gasspektroskopi massa (GC-MS). Yield terbesar diperoleh pada variasi feedstock 57 % (P) : 43 % (M) dengan jumlah fraksi hidrokarbon (< C7) sebesar 048 %, fraksi hidrokarbon (C8 - C12) sebesar 20,99 %, dan fraksi hidrokarbon (> C12) sebesar 78,53 % selang waktu perengkahan 1 jam. Data karakterisasi fisik berupa densitas, titik nyala, nilai kalor, dan RON telah diamati. Performa bahan bakar cair yang dicampur dengan bahan bakar komersial, Premium (RON 88), dan aditif metil tersier butil eter (MTBE) dengan perbandingan 225 (mL) : 750 (mL) : 18,25 (mL) menghasilkan efisiensi termal pada mesin generator set gasolin sebesar 28,22% di pembebanan 2118 Watt. Berdasarkan penelitian ini seluruh variasi feedstock menghasilkan bahan bakar cair yang sesuai dengan SNI 06-3506-1994 tentang mutu bahan bakar minyak jenis bensin.

Liquid fuel from polystyrene waste and cooking oil waste biodiesel was successfully obtained through catalytic cracking using Al-MCM-41/Ceramic. The structure, morphology, acidity, and porosity of the catalyst were studied by XRD, SEM-EDX, Piridine FTIR, and N2 gas adsorption-desorption. The products of catalytic cracking were analyzed using gas chromatogram-mass spectroscopy (GC-MS). The highest yield was obtained at feedstock variations of 57% (P): 43% (M) with the number of hydrocarbon fractions (< C7) is 0.48%, hydrocarbon fraction (C8 - C12) is 20.99%, and hydrocarbon fraction (> C12) is 78.53% in the cracking time 1 hour. Physical characteristics were reported in the form of density, flash point, heating value, and RON respectives. The performance of liquid fuels with commercial fuels, Premium (RON 88), and additives of methyl tertiary butyl ether (MTBE) comparisons of 225 (mL): 750 (mL): 18.25 (mL) respectively produce thermal efficiency on engine use gasoline generator sets is 28.22% at the load of 2118 Watts. Based on this research, all variations of feedstock produce liquid fuels that are in accordance with SNI 06-3506-1994 concerning the quality of gasoline fuel types.
