Process for separating components from gaseous streams

摘要

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 m2/g as determined by N2 adsorption at -196 DEG C., (ii) a crystallinity from about 5% to about 100%, and (iii) interstices from about 0.335 nm to about 0.67 nm.
