Multi-response optimization of MIL-101 synthesis for selectively adsorbing N-compounds from fuels
Abstract In this work, MIL-101, a metal organic framework, has been synthesized and examined in the adsorptive denitrogenation process. Due to the importance of adsorption capacity and selectivity, the effects of synthesis parameters including metal type, reagent ratio, time and temperature on the M...
