Thermal Behavior of Heavy Oil Catalytic Pyrolysis and Aquathermolysis

There is still considerable controversy surrounding the mechanisms, thermodynamics, and kinetics of heavy oil aquathermolysis pyrolysis processes. The present paper aims to widen our knowledge about effect iron tallates on Cuban oil. obtained SARA (S: saturates, A: aromatics, R: resins, asphaltenes) analysis has shown a significant increase in light hydrocarbon content during aquathermolysis. Moreover, elemental indicated an C H by almost 4% 6%, respectively, with decrease S O up 23% presence tallates. These results have been further confirmed infrared spectrometry. IR data that asphaltene resin compounds transform into hydrocarbons after On another hand, activation energy decreased utilized catalyst; meanwhile, reaction rate increased, especially temperature range 200–480 °C, which may validate used catalyst real conditions. thermodynamic showed enthalpy entropy Our are encouraging terms consumption, optimization, process control should be validated larger sample size.
