Abstract
|
Reports
catalytic aquathermolysis of Omani heavy oil using NiMo-oleate as an oil
soluble viscosity reducing catalyst and glycerol as a hydrogen donor.
Maximum viscosity reduction of 69% occurred at 277 °C reaction temperature and 30 h of reaction. Fourier transform infrared spectra (FT-IR) before and after catalytic aquathermolysis show an increase in the saturate bonds of alkyl groups and a decrease in unsaturated bonds of transalkene groups of the hydrocarbons indicative of hydrogenation activities of the catalyst and glycerol. In addition, gas chromatography (GC) analysis confirmed an increase in lower boiling point components after catalytic aquathermolysis, while asphaltene precipitation showed a decrease in asphaltene content. |
