Structural and thermal properties of vitrain lithotype in coal-inferences from TG-DTG-DSC, Rock-Eval and X-ray diffraction

Pore morphology in thermally-treated shales and its implication on CO2 storage applications: A gas sorption, SEM, and small-angle scattering study

“…Carbonate minerals such as siderite also decompose during Rock-Eval pyrolysis stage generating CO, CO 2 at temperatures > 400 • C and are represented as S3 ′ . Thus, elevated S3 ′ signals indicate presence of siderite [79,80]. We referred to Hazra et al (2022) [80] (and references within it) for understanding the impact of siderite on Rock-Eval S3 and S3 ′ .…”

“…Thus, elevated S3 ′ signals indicate presence of siderite [79,80]. We referred to Hazra et al (2022) [80] (and references within it) for understanding the impact of siderite on Rock-Eval S3 and S3 ′ . For the studied suite of samples, S3 ′ was observed to be similar for samples SH3 and SH6 (58.8 and 55.6 mg CO 2 /g rock, respectively) (Table 1).…”
