“…Many studies have been conducted on oil shale pyrolysis to better understand the effect of fundamental parameters on shale oil yield and quality to optimize the reaction conditions. This includes pyrolysis temperature [Chen and Shi, 2010;Williams and Ahmad, 1999;Yue et al, 2014], heating rate [Değirmenci and Durusoy, 2005;Nazzal, 2002;Williams et al, 1999;Yue et al, 2014], residence time for pyrolysis reaction [Williams and Chishti, 2001], composition of pyrolysis atmosphere [Netzel and Miknis, 1982;Razvigorova et al, 2008], particle size [Ahmad and Williams, 1998;Jaber et al, 1999;Khalil, 2013], and mineral matrix [Espitalie et al, 1980;Karabakan and Yürüm, 1998]. Vacuum pyrolysis has been shown to enable higher yield and improved quality shale oil in comparison with pyrolysis under atmospheric pressure [Hoekstra et al, 2012;Pakdel et al, 1999;Roy et al, 1985;Siramard et al, 2016].…”

The structure and connectivity of the pore space during the pyrolysis of oil shales determines hydrocarbon flow behavior and ultimate recovery. We image the time evolution of the pore and microfracture networks during oil shale pyrolysis using synchrotron X‐ray microtomography. Immature Green River (Mahogany Zone) shale samples were thermally matured under vacuum conditions at temperatures up to 500°C while being periodically imaged with a 2 µm voxel size. The structural transformation of both organic‐rich and organic‐lean layers within the shale was quantified. The images reveal a dramatic change in porosity accompanying pyrolysis between 390 and 400°C with the formation of micron‐scale heterogeneous pores. With a further increase in temperature, the pores steadily expand resulting in connected microfracture networks that predominantly develop along the kerogen‐rich laminations.

“…In studies between 1980 and 1996, Turkish researchers were widely using the single-reaction models in the explanation of the thermal decomposition process (Gunes, 1997). The single-reaction models were also preferred by recent studies (Ceylan and Olcay, 1998;Kucukbayrak et al, 2001;Guldogan et al, 2000Guldogan et al, , 2001aGuldogan et al, , 2001bGuldogan et al, , 2002Kok, 2003;Guruz et al, 2004;Kizgut and Yilmaz, 2004;Sinag, 2004;Degirmenci and Durusoy, 2005;Duz et al, 2005).…”

A multi-reaction model based on distributed activation energy has been applied to some Turkish coals. The kinetic parameters of distributed activation energy model were calculated via computer program developed for this purpose. It was observed that the values of mean of activation energy distribution vary between 218 and 248 kJ/mol, and the values of standard deviation of activation energy distribution vary between 32 and 70 kJ/mol. The correlations between kinetic parameters of the distributed activation energy model and certain properties of coal have been investigated.

Ulukışla oil shale in Turkey was pyrolysed at varying heating rates by thermogravimetric analysis. Kinetic analysis was undertaken at the decomposition steps of pyrolysis using the Coats & Redfern kinetic method. In addition, activation energies and reaction orders of the steps were calculated. Moreover, structural analysis of the oil shale sample was carried out by FTIR spectrometry, X-Ray diffractometry and XRF spectrometry.
