A cooling zone is then used to stabilize the adsorbent material after VOCs and HAPs have been desorbed. A concentrator—which may be available as an integral unit or as a set of individual ...
When gases desorb from a surface, they are ionized, examined, and compared with the temperatures at which they were desorbed. Small molecules, such as CO and H 2 O, typically attract interest. The MAX ...
For instance, adsorbed contamination becomes more mobile at high temperatures and may be entirely desorbed, but polymers cannot typically withstand temperatures above a few hundred degrees.
“Instead of a highly pressurized tank, we plan to store hydrogen in a low-cost powder material,” Mangum explained. “The hydrogen will be chemically and physically absorbed and desorbed. One of our ...
