This study investigated the integration of catalytic cracking - hydrotreating technology for the deoxygenation of waste cooking oil (WCO), and compared the integrated technology with hydrotreating alone on oxygen removal and the level of hydrogen consumption. The results showed that the performance of acid treated kaolin (ATK) was the best in the catalytic cracking section compared to that of the petroleum commercial catalyst (CC) and the alumina catalyst. The proposed catalytic cracking hydrotreating integrated technology presented in this work is a potential methodology for commercialization to achieve organic liquid products (OLPs) with low oxygenate content and low hydrogen consumption, which can reduce the oxygenate content from 87.6% to 6.6% and the hydrogen consumption from 8.8 mol to 2.4 mol per mol of tryglyceride.
