Kinetic modelling of kerogen cracking during oil shale process : influence of organic matter source

摘要

1. First step : kerogen cracking 1.1 Most of the asphaltenes are degraded 1.2 Resins are more stable class 1.3 C_(14+) aromatics start to be cracked at high kerogen conversion 1.4 C_(14+) saturates are almost stable Still high content in -NSOs (asp + resins): production of low °APi and low mobility fluid, → significant secondary cracking reaction 2. Second step : influence of the secondary cracking reaction 2.1 Available compositional kinetic schema.
