Thermodynamic modelling of the system was conducted in Aspen Plus V12, applying the Gibbs free energy minimization method and accounting for all by-products. Key decision variables, including the water-to-glycerol ratio, CO₂-to-glycerol ratio, and reforming temperature, were examined for their impact on process performance. Results demonstrated that bi-reforming glycerol is more advantageous for syngas production compared to dry reforming, as it operates at lower temperatures, reducing coke formation. A glycerol bi-reforming process was simulated and optimized using MOO to maximize syngas production and CO₂ conversion while minimizing exergy loss and CO₂ emissions. The optimization revealed trade-offs among the objectives, with the Pareto front showcasing optimal solutions. Specifically, a higher water-to-glycerol ratio favoured a higher H₂-to-CO ratio but led to decreased CO₂ conversion and increased energy consumption and CO₂ emissions. The net flow method (NFM) is used to select the best optimal solutions from the Pareto front solutions based on the weight of the objective functions. Despite these trade-offs, bi-reforming of bio-glycerol was shown to be a viable method for producing syngas with a high H₂/CO ratio and low CO₂ emissions.

Oilfield produced water is a type of lithium-containing wastewater generated during oil extraction processes, offering significant potential for resource recycling.

To enhance lithium recovery efficiency from oilfield wastewater, this study synthesized lithium manganese oxide (Li₁.₆Mn₁.₆O₄) via a soft chemical method using various lithium and manganese sources, followed by surface modification with lanthanum oxide (La₂O₃). The La₂O₃-modified material was applied for cyclic adsorption and recovery of Li⁺ from oilfield produced water. Experimental results indicate that combining MnCO₃ and LiOH as manganese and lithium sources in a 1:1 ratio produces the Li₁.₆Mn₁.₆O₄ precursor with optimal adsorption capacity and minimal manganese loss. Through multiple adsorption-desorption cycles using both simulated and actual oilfield produced water samples from various locations, it was demonstrated that the inherent chemical inertness of La₂O₃ coating on Li₁.₆Mn₁.₆O₄ effectively mitigates manganese dissolution. La₂O₃ coating effectively mitigates manganese loss from Li₁.₆Mn₁.₆O₄. After 10 cycles, the manganese loss rate remained below 1.5 %, with the adsorption capacity sustained at 25 mg·g⁻¹ .
