Microwave-synthesized composite preformed particle gels based on tragacanth gum and palygorskite for high-salinity high-temperature conditions
منشور في 2025"…Swelling behavior in real Gulf seawater (TDS = 45,2 mg/L) and rheological measurements taken at elevated temperatures (80 °C and 100 °C) showed that the addition of Pal enhanced gel rigidity but slightly reduced swelling capacity, likely due to increased steric hindrance. The formulation TPAC<sub>2</sub> (2.5 g Pal) exhibited an optimal balance between swelling (14.2 g/g at 100 °C) and mechanical strength, making it a strong candidate for reservoir applications. …"
