Abstract
The present invention relates to the separation of one or more components from a multi-component gaseous stream. The component(s) being separated are relatively small molecular diameter gas components. They are separated by sorption techniques wherein the sorbent is a unique class of layered nanostructure materials, such as carbon nanofibers, characterized as having; (i) a surface area from about 0.2 to 3,000 m.sup.2 /g as determined by N.sub.2 adsorption at -196.degree. C., (ii) a crystallinity from about 5% to about 100%, and (iii) interstices from about 0.335 nm to about 0.67 nm.
