Abstract: An adsorbent media has a pore volume/media volume of at least about 0.12 cc pore volume/cc media, a specific heat capacity of less than about 2.9 J/cc pore volume, and a pressure drop of less than about 4.0 inH2O/ft media at a superficial air velocity of about 500 ft/min, wherein the adsorbent media is in a concentrator system. An extruded honeycomb adsorbent media has a cell density of more than about 200 cells per square inch (cspi), % open area of at least about 50%, an activated carbon content of at least about 50% by weight based on total weight, and a pressure drop of less than about 4.0 inH2O/ft media at a superficial fluid velocity of about 500 ft/min.

Abstract: A refractory brick made from a size graded batch comprising 20-30 weight percent magnesite containing less than 0.8 weight percent silica, and the balance a chrome ore. The chrome ore includes oxides of chromium, aluminum and iron wherein the ratio between the oxides of chromium and the oxides of aluminum and iron is greater than 2 to 1. The silica content of the chrome ore is less than 2.7 weight percent, the iron oxide content is less than 17 weight percent, and the chrome ore to magnesite ratio is between 2.33 to 4 to 1.
