“…In various studies, these interactions resulted in non-linear changes in yields, unlike the linear changes in yields from the individual pyrolysis of FS. The interactions also increased the yield of oil and its H/C ratio, as observed by Chen et al [79], and the yield of gas while reducing that of solid residues [80,82,[84][85][86]. The synergetic effect of co-pyrolysis can depend on the blend ratio of BM:OS, as shown by Dai et al [84], who demonstrated a maximum synergy at 30 wt% blends of OS using microalgae and OS.…”

“…For microalgae and OS, higher OS amounts delayed thermal decomposition [84]. A study by Chen et al [79] on wood pellets and OS blends showed that BM:OS ratios of 3:1 and 1:1 resulted in a decrease in oil yield (from 19.7 wt% for pure OS to 10-13 wt% for BM:OS ratios of 3:1 and 1:1), inhibition of the production of heteroatomic hydrocarbons and promotion of that of unsaturated hydrocarbons.…”

“…Co-processing of OS and BM has the potential to reduce various challenges from individual pyrolysis while producing higher yields of bio-oil with improved composition [60]. BM for char, oil and gas production is pyrolyzed at temperatures of 350-500 °C, which are within the same temperature range of OS retorting [79]. The bio-oils obtained from BM pyrolysis have very different characteristics from those of shale oil.…”

“…The yield of shale oil has been studied by Jaber et al [177] and Olukcu et al [178] at different temperatures in the 500-700 °C range. This temperature range has been used in numerous studies of the OS conversion process [39,79,80,113,164,175,176]. Several studies have found that temperature affects the yield of OS, resulting in a maximum yield in the range of 450-550 °C, with 520-525 °C being optimal for producing the highest shale oil yield [79,93,111,113,140,174].…”

The use of biomass (BM) and oil shale (OS) blends for the production of cleaner and improved fuels and chemicals through co-pyrolysis has recently attracted attention. The potential benefits, synergetic effects, interactions and promotion and inhibition effects of co-pyrolysis of BM and OS are reviewed and analyzed in this article based on an overview of various recent studies of co-pyrolysis, including the experimental and operational parameters and the yield and composition of the products. The effects of co-pyrolysis on different feedstock blends are discussed to guide future research on BM and OS copyrolysis. The effects of different pyrolysis parameters that can improve the pyrolysis process and quality of products are also reviewed. These parameters include CO 2 and steam atmospheres, heating rate, reaction temperature and particle size. Overall, in most cases reviewed, co-pyrolysis can enhance the yields of bio-oils, producer gas and chars as well as improve their properties while reducing the environmental effects of fossil fuels.

“…Oil shale (OS) is a fine‐grain sedimentary rock containing complex solid macromolecular organic matter called kerogen, 9 from which petroleum‐like shale oil can be extracted. OS is one of the most promising alternative resources for petroleum, 10 due to its huge reserves 11 as well as the similar properties of shale oil and crude oil 12,13 . Its reserves are equivalent to 5.4 times of the world's proven recoverable oil reserves 11 .…”

Structural and quantitative evolution of organic matters in oil shale during two different retorting processes

et al. 2021

In this study, traditional strongly endothermic anaerobic retorting (AR) and relatively novel self‐heating retorting (SHR) processes for oil shale (OS) were investigated and compared in detail. These studies mainly involve the structural and quantitative evolution of organic matters in OS during retorting, including varieties of crystallite parameters, carbon framework structure, amounts of various structural carbons and toxic polycyclic aromatic hydrocarbons, and so on. The obtained results well elucidate some reaction pathways in AR and SHR as well as certain differences between the two retorting processes. Moreover, based on our former work that verifies SHR greatly simplifies retorting operation by in situ generating heat to replace external heat carrier/provision, this study further demonstrates that SHR also alleviates the environmental effect of organic toxic residues as compared to AR. The present study provides some critical results not only for penetrating the reaction mechanism but also for assessing or controlling the environmental impact of both retorting processes.
