Cracking Process

Waste Cooking Oil (WCO) can be a alternative for petroleum-based fuel. In this work, green biofuel was produced via cracking process of high acid value (AV) waste cooking oils (WCOs) over spent fluid catalytic cracking (SFCC) catalyst collected from Binh Son Refireny. The influences of temperature (450 – 520°C), catalyst-to-WCO ratio (1.5 – 3.5), and acid value (6 - 22 mgKOH/g) have been examined. At 520°C, WCOs can be converted to liquid fuels with the near zero AV (AV 0.5 mgKOH/g) which is independent of AV of WCOs. In all cases, the total yield of profitable products, gasoline-diesel-LPG, reaches 85 wt%, with only 5 - 7 wt% of coke yield. This study demonstrated the simultaneous utilization of multiple hazardous substances, SFCC catalyst and WCOs, as low-cost raw materials for biofuel production.

<p>Liquid fuel from polystyrene waste and waste cooking oil biodiesel was successfully obtained through catalytic cracking using Al-MCM-41/Ceramic. The structure, morphology, acidity, and porosity of the catalyst were studied by SEM-EDX, pyridine FTIR, and N<sub>2</sub> 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 (&lt; C<sub>7</sub>) is 0.48%, hydrocarbon fraction (C<sub>8 </sub>- C<sub>12</sub>) is 20.99%, and hydrocarbon fraction (&gt; C<sub>12</sub>) is 78.53% in the cracking time 1 hours. Physical characteristics were reported in the form of density, flash point, and caloric value respective. 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 was 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.</p><p> </p>Keywords: Catalytic cracking, polystyrene waste, waste cooking oil, liquid fuel

Biodiesel Synthesis

The synthesized nanomaterials by two different methods were used as a catalyst in the transesterification of waste cooking oil to produce biodiesel. For both environmental and economic reasons, it is beneficial to produce biodiesel from waste cooking oils. It is desirable to help solve waste oil disposal by utilizing its oils as an inexpensive starting material in biodiesel synthesis. The structure, morphology, and surface properties of resulting nanocatalysts were characterized by X-ray Fluorescence Spectroscopy (XRF), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Energy Dispersive X-ray Spectroscopy (EDX) and N2 adsorption-desorption isotherms. The synthesized nanocatalysts' efficiency in the production of biodiesel was studied by Gas Chromatography (GC) as well as leaching amounts of surface active components of each catalyst investigated by the EDX technique. The reactions were performed at 65°C using a 9:1 methanol to oil ratio for 3 h. The results indicate that the impregnated mixed metal oxide catalyst ( Ca-MgAl) shows a higher surface area and better mechanical strength than the totally co-precipitated mixed metal oxide catalyst (CaMgAl(O)). Although both of the fully co-precipitated and impregnated catalysts represented about 90% of fatty acid methyl esters (FAME) yield the leaching of active calcium component was significantly reduced from 45.8% in precipitated CaMgAl(O) to 8% for the impregnated Ca-MgAl catalyst. This improved structure represents the advantage of the impregnation technique to co-precipitation procedure for fabrication of robust nanostructures.
