| 摘 要： | This paper illustrates the reaction pattern of catalytic degradation of macromolecules in asphaltic sands. Such parameters as ionic liquid catalyst system and H^ proton donor, that affect the change of the organic phase and the mass of organic matter in residual phase of asphaltic sands, were investigated. It was found that chloroaluminate (Ⅲ) ionic liquid/H3PO4 systems as reaction medium was an effective catalyst system for asphaltic sands degradation. The catalytic degradation of asphaltic sand swas related to the kinds of chloroaluminate (Ⅲ) ionic liquids and H^ proton donor. In BMIM] AlCl4]/H3PO4 reaction catalytic medium, the degradation of asphaltenes in the organic phase reached 16.44 %, the degradation of asphaltenes in the residual phase reached 30.74%. TLC-FID analysis of asphaltic sands showed that the main degradation products were saturates and aromatics, and resin fractions as well. At a temperature close to oil-bearing formation and with absense of oxygen, the yield of H2S reached 74%,which indicated that catalytic degradation of sulphur-containing compounds was easier.

| Abstract: | This paper illustrates the reaction pattern of catalytic degradation of macromolecules in asphaltic sands.Such parameters as ionic liquid catalyst system and H+ proton donor,that affect the change of the organic phase and the mass of organic matter in residual phase of asphaltic sands,were investigated.It was found that chloroaluminate (Ⅲ) ionic liquid/H3PO4 systems as reaction medium was an effective catalyst system for asphaltic sands degradation.The catalytic degradation of asphaltic sands was related to the kinds of chloroaluminate (Ⅲ) ionic liquids and H+ proton donor. In ［BMIM］［AlCl4］/H3PO4 reaction catalytic medium, the degradation of asphaltenes in the organic phase reached 16.44%, the degradation of asphaltenes in the residual phase reached 30.74%.TLC-FID analysis of asphaltic sands showed that the main degradation products were saturates and aromatics,and resin fractions as well.At a temperature close to oil-bearing formation and with absense of oxygen,the yield of H2S reached 74%, which indicated that catalytic degradation of sulphur-containing compounds was easier. |
