ALEXANDRIA, Va., March 17 -- United States Patent no. 12,576,385, issued on March 17, was assigned to Dow Global Technologies LLC (Midland, Mich.).
"Carbon molecular sieve adsorbent monoliths and methods for making the same" was invented by Junqiang Liu (Freeport, Texas) and Janet M. Goss (Saginaw, Mich.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Methods for forming a carbon molecular sieve includes loading polymer fibers into a mold and heating the mold containing the polymer fibers to a temperature in a range from 50deg C. to 350deg C. to form a polymer monolith. The polymer monolith is then pyrolized by heating to a temperature in a range from 500deg C. to 1700deg C. A carbon molecular sieve monolith ...
