Mechanism of kerogen pyrolysis in terms of chemical structure transformation
TL;DR: In this article, an overview on carbon chemical structure transformation to understand kerogen thermal decomposition based on the chemical structure of kerogen is presented, and an updated lumped mechanism model is proposed for viewing kerogen pyrolysis and provides a basis for understanding the transformation of carbon chemical structures.

Secondary reactions in oil shale pyrolysis by solid heat carrier in a moving bed with internals
TL;DR: In this article, the secondary reactions occurring during the formation of shale oil are investigated with Huadian oil shale pyrolysis by solid heat carrier in a newly devised moving bed with internals (MBI).
Journal ArticleDOI
Secondary Cracking and Upgrading of Shale Oil from Pyrolyzing Oil Shale over Shale Ash
TL;DR: In this paper, the authors investigated the effect of shale ash, as the bed material for secondary reactions of pyrolysis volatile, on final product distribution and quality of oil shale pyrotechnics in a laboratory dual-stage fixed bed reactor.
Journal ArticleDOI
Pyrolysis of oil shale by solid heat carrier in an innovative moving bed with internals
TL;DR: In this paper, a new moving bed with particularly designed side and central channels as its internals for small-size oil shale pyrolysis by solid heat carrier is reported.
Journal ArticleDOI
A comprehensive review of microwave application on the oil shale: Prospects for shale oil production
TL;DR: In this paper, the authors reviewed the mechanism of microwave irradiation and the affecting parameters, including heating rate, particle size, catalysts, and supercritical fluids on the microwave induced pyrolysis of oil shales.

Continuous fluidized bed retorting of Condor and Stuart oil shales in a 150 mm diameter reactor
TL;DR: In this paper, a pyrolysis of Condor and Stuart oil shales in a continuous fluidized bed reactor heated by through-wall thermal conduction gave oil yields close to modified Fischer Assay; however, when these shales were pyrolysed in the same reactor with an ash-to-shale recycle ratio of two, there was up to 28 % oil loss.

Kinetics of coking shale oil vapour on combusted spent shale for eight Australian oil shale deposits
Geoffrey C. Wall,Pinky Udaja +1 more
TL;DR: In this paper, the authors presented data on the kinetics of coking at 500 °C of shale oil vapours on combusted spent shale (shale ash) prepared from samples of oil shales from the Condor, Duaringa, Lowmead, Nagoorin, NN South, Rundle, Stuart and Yaamba deposits and made recommendations for the selection of retort operating conditions to minimize oil yield losses due to coking.
Journal ArticleDOI
Vapour phase cracking and coking of three Australian shale oils: kinetics in the presence and absence of shale ash
TL;DR: In this paper, the vapour phase thermal behavior of shale oil samples derived from the Condor, Nagoorin carbonaceous and Stuart deposits was examined, and it was found that the oils vaporized in argon were passed through packed beds of sand, or the spent shale ash corresponding to the particular oil, at temperatures between 500 and 600 °C, over a range of residence times.

The role of catalysis by mineral matter during oil shale retorting
K. Jacob Soerensen,Noel W. Cant +1 more
TL;DR: In this paper, the influence of catalysis by mineral matter in determining the composition of shale oil produced by retorting is investigated using, as test reactions, the isomerization of 1-octene and cyclopropane and the cracking of octene and isopropylbenzene.

Pyrolysis of stuart oil shale in the presence of recycled shale
TL;DR: In this article, the pyrolysis of Stuart oil shale in the presence/absence of fully combusted shale (shale ash) in superheated steam or nitrogen was conducted in the range 450 to 600 °C in a 48 mm diameter semi-continuous fluidized-bed reactor.
