Multi-stage kinetic analysis and product distribution prediction for oil shale pyrolysis
摘要:Oil shale represents an unconventional hydrocarbon resource with strategic importance for energy security. This study develops a comprehensive kinetic framework for oil shale pyrolysis that integrates constrained Fraser-Suzuki (FS) deconvolution, isoconversional activation-energy estimation, Sestak-Berggren (SB) unified conversion-function fitting, and multi-parameter response prediction. Multi-heating-rate thermogravimetric analysis (TGA) data were employed to deconvolute overlapping derivative thermogravimetric (DTG) peaks, followed by cross-validation of activation energies using both the Friedman and Starink methods. The kinetic compensation effect (KCE) was incorporated as a physical constraint to ensure parameter reliability. The optimized kinetic parameters were subsequently coupled with an Organic Matter Pyrolysis Model (OMPM) to predict product distribution. Results demonstrate that the six-peak deconvolution scheme adequately characterizes the major mass-loss features in the DTG curves. Kinetic fitting and subsequent product prediction were performed for the four organic peaks (Peaks 1-4), whose activation energies range from 179.5 to 283.2 kJ & sdot;mol-1. The model exhibits predictive capability across both training conditions and extrapolated low-heating-rate scenarios, providing a kinetic foundation for in-situ conversion process optimization.
