Glycerin-based adsorbents for the separation of ethane and ethylene

Autor: Moisés L. Pinto, João Pires, Renato Carvalho, M. K. S. Batista

Publikováno v: Colloids and Surfaces A: Physicochemical and Engineering Aspects. 634:127975

The separation of ethane from a mixture of ethane/ethylene is a large scale process. Therefore, if adsorption is to be considered for this separation, besides the amounts adsorbed and selectivity type and values, the adsorbent also needs to have a re
