Gas evolution during kerogen pyrolysis of Estonian Kukersite shale in confined gold tube system

•Thermally initiated evolution of C1–5 was given in pyrolysis of Kukersite kerogen.•Four distinct stages divided the pyrolysis based on gas yields and δ13C values.•An order of C5>C4>C3>C2>C1 (increase ratio) was shown at low maturities (C2>C3>C4>C5 occurred at higher maturities...
