Abstract: Biofuels were produced with waste cooking oil by Fluid Catalytic Cracking (FCC). The catalytic reactions involved two catalysts of Endurance and CGP-1HN, which were characterized by Scanning Electron Microscopy (SEM), N2 Adsorption-Desorption, X-ray Diffraction (XRD) and Pyridine Fourier Transform Infrared Spectroscopy (Py-FTIR). The results indicated that the structure and properties of Endurance and CGP-1HN were similar, and the most obvious difference between them was a different content of acid sites. The Lewis and Brönsted acid contents of Endurance were 189.39 and 341.69 μmol/g, respectively, and the Lewis and Brönsted acid contents of CGP-1HN were 21.53 and 258.23 μmol/g, respectively. The different acid sites resulted in different distributions of products under the same reaction conditions. A higher diesel yield (32.04 wt%) was achieved using Endurance, and a higher Liquefied Petroleum Gas(LPG) yield (42.71 wt%) was produced using CGP-1HN. The result shows that different type acid and acid contents effect on the product distribution. The Lewis acid sites decreases the catalytic cracking depth of waste cooking oil.
