Experimental and simulation study of CO2 breakthrough curves in a fixed-bed adsorption process

This paper focuses on the laboratory experiments of low-temperature adsorption CO2 at elevated pressure and validation our mathematical model with data obtained. The numerical approach uses fitting isotherm parameters sensitivity analysis influencing breakthrough curve shape onset time. We first evaluate results for zeolite 13X. Then, we use obtained to design a dynamic predict profile. Experimental show that 13X possesses high capacities (over 10 % its weight temperatures 293 K below), as expected. simulation was accurate predicting time; however, this prediction accuracy declined outlet concentration exceeding 75 %, which is discussed. indicated choice different estimates mass transport bed porosity, well scheme, can lead more prediction, but same set not suitable all process conditions.
