Summary: This study investigated the thermal behavior, synergistic effect, and reaction mechanism of co-pyrolysis of oil-based drill cuttings (OBDC) and pinewood sawdust (PS). The results showed a positive synergistic effect in the co-pyrolysis, with the strength increasing as the percentage of PS in the blend increased. The apparent activation energy was evaluated using two model-free methods and the reaction mechanism was found to be a combination of reaction order, accelerating, and nuclei growth and diffusion mechanism.

Summary: Fuling shale gas field in Chongqing, the largest shale gas exploration site in China, generates a significant amount of hazardous waste called oil-based drill cuttings (OBDC) annually. Traditional treatment methods fail to recover valuable components such as petroleum hydrocarbons, while pyrolysis has proven to be an efficient method for their recovery. This study investigates the kinetics of pyrolysis using two different methods and evaluates the human health risk and ecological risk before and after pyrolysis. The results show that pyrolysis can significantly reduce non-carcinogenic risk, carcinogenic risk, and ecological risk, although the carcinogenic risk after pyrolysis still exceeds the critical value.

Summary: Shale gas, as an emerging oil-bearing and pillar industry both domestically and internationally, has a significant impact on economic development and industry, but the resulting emerging pollutants pose a serious threat to the environment. Drilling cuttings, the primary byproduct of shale gas exploration and mining, are potentially hazardous waste types that seriously deplete land resources and pose environmental safety problems. Through a long-term static volatilization experiment, it was found that polycyclic aromatic hydrocarbons (PAHs) in the oil-based residue of shale gas drill cuttings exhibited increasing volatilization concentrations over time, with smaller ring numbers of PAHs being more readily volatilized. The study also showed that different environmental factors had varying effects on the volatilization of PAHs, with temperature, illuminance, and particle size playing key roles in increasing volatility.

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: This study examines the preparation of low-density and high-performance proppants using water-based drill cuttings (WBDC) and bauxite as raw materials. Various factors such as sintering temperature, sintering period, material ratios, doping with iron oxide, and acid modification of WBDC are investigated for their effects on proppant properties. The proppant's performance is evaluated according to national standards, and its morphology and crystal phase structure are analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively. Proppant Z-23 satisfies the standards completely, offering a new perspective for the resource utilization of WBDC and the preparation of low-density proppants.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
