抄録

Athabasca oil sand bitumen was hydrocracked over ZnCl2-KCl-NaCl melt and ZnCl2-KCl-NaCl-MoCl5 melt at temperatures from 350°C to 400°C for 3 hours with an initial hydrogen pressure of 100kg/cm2. In respect of distribution of products such as gas, pentane soluble (PS) and benzene soluble (BS), ternary melt catalyzed run at 375°C is roughly equal to the run without catalyst at 400°C, while the runs at 375°C and 400°C with the ternary melt are similar to the ones at 350°C and 375°C with the quarternary melt, respectively (assuming the sum of gas and PS as light hydrocarbon). Elementary analyses, a simulated distillation and chromatographic separation of the resulting PS, clarified the characteristics of the melt catalyst: 1, the degree of hydrodesulfurization increases from without catalyst to the quarternary melt via the ternary melt; 2, a simulated distillation confirms that the ternary melt at 375°C is roughly equivalent to the quarternary melt at 350°C; 3, the quarternary melt is excellent in assisting hydrogenation of polyaromatics and removal of heteroatoms. The coke formation, accompanied with hydrocracking of bitumen, might be attributed partly to resin fraction, besides asphaltene fraction, based on hydrocracking of maltene and resin, and structural study of the resulting PS fraction from resin.
