Abstract
Bahan bakar cair dari limbah plastik polistiren dan ko-reaktan biodiesel minyak jelantah telah berhasil diperoleh. Katalis yang digunakan dalam proses perengkahan katalitik yaitu katalis Al-MCM-41/keramik dan katalis Pd/Al-MCM-41/keramik. Morfologi dan komposisi unsur diamati dengan SEM EDX, struktur kristal diamati dengan XRD, luas permukaan dan volume pori dianalisis dengan adsorpsi-desorpsi N2 yang masing-masing dihitung dengan metode BET dan BJH, keasaman ditentukan dengan FTIR-Piridin, dan ketahanan suhu dianalisis dengan DTA. Hasil perengkahan katalitik diselidiki menggunakan Gas Chromatography-Mass Spectroscopy (GC-MS). Karakterisasi katalis menunjukkan bahwa keasaman Al-MCM-41/keramik menurun karena rasio Si/Al menurun, luas permukaan menurun, dan volume pori meningkat setelah impregnasi Pd. SEM EDX menunjukkan bahwa komposisi unsur karbon pada permukaan katalis Pd/Al-MCM-41/keramik lebih kecil dibandingkan dengan katalis Al-MCM-41/keramik. Hasil karakterisasi GC-MS terhadap bahan bakar cair dari perengkahan katalitik menggunakan katalis Pd/Al-MCM-41/keramik, memiliki persentase yield sebesar 89% dan fraksi gasolin (C7-C12) sebesar 74,9% pada perengkahan selama 120 menit.

Liquid fuel from polystyrene plastic wastes and co-reactant biodiesel from waste cooking oil have been successfully obtained. The catalyst used in the catalytic cracking process is Al-MCM-41/ceramic and Pd-Al-MCM-41/ceramic catalysts. Morphology and elemental composition observed by SEM EDX, the crystal structure observed by XRD, the surface area and pore volume analysed by N2 adsorption-desorption which were calculated using BET and BJH method, respectively, the acidity that determined by pyridine and FTIR, and temperature resistance analized by DTA. The liquid fuel were investigated using Gas Chromatography-Mass Spectroscopy (GC-MS). The characterization of catalyst showed that the acidity of Al-MCM-41/ceramic was reduce because the ratio of Si/Al was decrease, surface area was decrease, and pore volume was increase after Pd impregnation. SEM EDX shows that the composition of the carbon element on the surface of the Pd/Al-MCM-41/ceramic catalyst is smaller compared to the Al-MCM-41/ceramic catalyst. The results of GC-MS characterization of liquid fuels from catalytic cracking using Pd/Al-MCM-41/ceramic catalysts, have a yield percentage of 89% and gasoline fraction (C7-C12) of 74.9% in cracking for 120 minutes.
