The adsorption characteristics of MOF⁃derived porous carbon and powdered activated carbon for No.2 oilwere systematically investigated. The effects of adsorption time, adsorbent dosage, temperature, and pH on their adsorptionperformance were examined in detail, and the adsorption mechanisms were thoroughly discussed. Results demonstratethat MOF⁃derived porous carbon exhibits superior pH tolerance compared to powdered activated carbon. Under optimalconditions, the equilibrium adsorption capacities of MOF⁃derived porous carbon and powdered activated carbon forNo.2 oil reach 224.95 mg/g and 194.86 mg/g, respectively. Adsorption kinetic analysis reveals that both follow the pseudo⁃second⁃order kinetic model with correlation coefficients R2 > 0.999. Thermodynamic studies indicate that the adsorptionof No.2 oil by MOF⁃derived porous carbon is an exothermic process dominated by physical adsorption.
