Abstract
The paper focuses on investigating the impact
of mineral components of Meihekou oil shale on the conversion of organic carbon
from the oil shale into shale oil. A number of leaching operations were
performed and each product formed in the bioleaching process was analyzed. The
analysis showed that the bioleaching technology used is best for oil shale
conversion.The yield of shale oil was from 8.3% to 11.2%, and approximately
8.4% of extra shale oil was obtained. During bioleaching a lot of micropores
were generated in oil shale, which is favorable to transfer heat from the
outside into the inside of the bioleached oil shale sample. Therefore, more
shale oil could be obtained through the micropores rapidly, which may avoid
shale oil from cracking into shale gas. Finally, bioleaching contributes to the
production of more shale oil.
