  4. Abstract:
  5. A two-stage thermocatalytic upgrading process using a novel catalyst was investigated to produce light olefins and liquid fuels from fuel oil. The upgraded oil from the first thermal stage demonstrated lower viscosity and higher crackability compared to the virgin feedstock. In the next step, the vapor-phase catalytic cracking of the upgraded fraction was implemented over a novel nanoporous composite catalyst, characterized by the XRD, FTIR, NH3- TPD, and N2 physisorption techniques. In total, more than 55 wt% of light olefins, particularly propylene (25.5 wt%) together with 25.4 wt% and 32.5 wt% of gasoline and diesel fuel were obtained in this process. © 2019, © 2019 Taylor & Francis Group, LLC
