Optimization of gas injection process and pyrolysis temperature for autothermic in-situ conversion of oil shale with varying oil content

Key Points

• Conversion efficiency improved with optimized gas injection, leading to better energy output.
• Pyrolysis at higher temperatures resulted in enhanced oil recovery from oil shale, reaching up to 85 percent efficiency.
• Assessment using variable pyrolysis temperature and gas injection methods provided critical insights into operational parameters.
• This analysis highlights the need for further studies on long-term efficiency and viability of the autothermic process.
