Abstract
  Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations ...  Read More

Javad Esmaili; Mohammad Reza Ehsani

Volume 3, Issue 3 , Summer 2014, , Pages 39-46

http://dx.doi.org/10.22050/ijogst.2014.6620

Abstract
  In this paper, the development of a new potassium carbonateon alumina support sorbent prepared by impregnating K2CO3 with an industrial grade of Al2O3 support was investigated. The CO2 capture capacity was measured using real flue gas with 8% CO2 and 12% H2O in a fixed-bed reactor at a temperature of ...  Read More
