Summary: The partial replacement of fossil fuels with biomass has the potential to produce cleaner and more sustainable energy and fuels. Co-pyrolysis of biomass and oil shale using conventional shale oil production infrastructure can reduce the use of oil shale and its environmental impact. Adding woody biomasses to oil shale during co-pyrolysis showed increased decomposition and production of combustible gases, while alternative atmospheres contributed to a lower share of residual mass.

Summary: Biomass torrefaction followed by co-pyrolysis with oil shale has great potential in upgrading bio-oil. A comparative analysis of oil shale co-pyrolysis with raw/torrefied corn stalk was conducted. Oil shale played a key role in promoting oil yield during co-pyrolysis, but only after corn stalk torrefaction. The optimal blending ratio of oil shale for both raw and torrefied corn stalk is 50%.

Summary: A new method of upgrading pyrolysis products through co-pyrolysis polygeneration and bio-oil recycling was proposed in this study. The results showed that the leaching pretreatment effectively removed alkali metals from pine wood, improving the quality and energy yield of bio-oil during subsequent pyrolysis. The co-pyrolysis of pine wood and heavy bio-oil had a synergistic effect, increasing the mass yield of biochar and pyrolysis gas while improving the contents of CO and C2+ gases in the gaseous products. This method provides a potential way to classify and utilize light and heavy components of bio-oil.

Summary: Co-pyrolysis of oil shale and corn stalk can enhance thermal decomposition and improve the quality of products. The addition of corn stalk promotes the decomposition of cellulose and advances the decomposition temperature of oil shale, while reducing the decomposition rate. Furthermore, co-pyrolysis hinders the release of oxygen-containing gases, but catalyzes the bond breaks in oil shale by adsorbing H2O and CO2.

Summary: In order to address the issues of low oil yield in oil shale and high oxygen content in biomass pyrolysis oil, the co-pyrolysis of oil shale and peanut shell was studied using thermogravimetric analyzer and fixed bed reactor. Through analysis of co-pyrolysis characteristics, kinetics, and oil phase products, a series of co-pyrolysis interaction mechanisms were proposed. The co-pyrolysis led to earlier decomposition of oil shale and higher conversion rate of the blended feedstock. The interaction at different temperatures was dominated by oil shale radicals and minerals catalysis at low temperatures, and by biomass alkali/alkaline earth metals at high temperatures. These interactions promoted the formation of aliphatic and aromatic hydrocarbons in the oil, reducing carbon chain length and increasing light oil content.

Summary: An experimental investigation was conducted to study the characteristics and transformation mechanism of Jimsar oil shale and derived shale oil. Solid-state nuclear magnetic resonance spectrometer, Fourier transform infrared spectroscopy, liquid H-1 NMR, and gas chromatography-mass spectrometry techniques were used. The carbon skeleton structure of Jimsar oil shale is mainly composed of aliphatic carbons and aromatic carbon. Derived shale oil is primarily made of aliphatic compounds dominated by n-alkanes and alkenes. The conversion process involves decomposition of aliphatic groups with methylene structures. Increasing the heating rate promotes secondary cracking reactions in shale oil and enhances the generation of cycloalkanes and aromatic compounds. Shale oil has the maximum yield value, the highest contents of carbon, hydrogen, and nitrogen, and the lowest oxygen content at a pyrolysis heating rate of 5 degrees C/min.

Summary: The catalytic effect of several additives on the co-pyrolysis of Huadian oil shale and microalgal powder was investigated. CaO and Al2O3 showed significant potential for reducing the oxygen content of the oil and improving its quality. CaO facilitated dehydrogenation and alkene formation, while Al2O3 increased the H/C ratio and improved oil quality. ZSM-5 had negligible catalytic performance for deoxygenation. Al2O3 was selected as the most suitable additive for the co-pyrolysis process.
