Abstract

Molybdenum oleate was synthesized from oleic acid and ammonium molybdate. The effects of the hydrogen donor of tetralin

the catalyst dosage

reaction temperature and reaction time on viscosity reduction of heavy oil were studied. The optimum reaction conditions were determined as follows: the amount of catalyst was 0.8 wt%

the reaction temperature was 240?C

the reaction time was 18 h

and the viscosity reduction rate of heavy oil was 65.87%. The four components analysis showed that the content of asphaltene and resin decreased

however

the content of saturate and aromatic increased after reaction. Gas chromatography

elemental analysis and infrared spectroscopy were used to analyze the changes of cracking gas composition

elemental content and four-component structure before and after heavy oil reaction

and the reasons for viscosity reduction of heavy oil were discussed. Finally

the reason of viscosity change in oil sample after a period of time was analyzed.
