POROUS MATERIALS FOR CONCENTRATION AND SEPARATION OF HYDROGEN OR HELIUM, AND PROCESS THEREWITH FOR THE SEPARATION OF THE GAS

A porous material for use for separation of gases having a molecular weight not larger than 4, such as hydrogen or helium in a high concentration from a mixture gas containing such gases, comprising not less than 50% of pores having a diameter ranging from 110 to 160 .ANG. with respect to the total...

Beschreibung
Zusammenfassung:	A porous material for use for separation of gases having a molecular weight not larger than 4, such as hydrogen or helium in a high concentration from a mixture gas containing such gases, comprising not less than 50% of pores having a diameter ranging from 110 to 160 .ANG. with respect to the total pore volume, said pore diameter being determined by nitrogen adsorption measurement.
