| Abstract: |
| Methyl stearate was chosen as model compound absorbed by S3 and S4 source rocks of Dongying depression. The effects of salinity,pH value, temperature and pressure on the hydrolysis and hydrocarbon generation of fatty acid ester were investigated by kinetics method, and the kinetic parameters were obtained. The results show hydrolysis and hydrocarbon generation of fatty acid ester can be catalyzed by source rocks. The activation energy of hydrolysis catalyzed by S3 is bigger than that by S4, which is correlative to contents of clay. |
