Abstract: A sorbent structure that includes a continuous body in the form of a flow-through substrate comprised of at least one cell defined by at least one porous wall. The continuous body comprises a sorbent material carbon substantially dispersed within the body. Further, the temperature of the sorbent structure can be controlled by conduction of an electrical current through the body.

Abstract: The present invention describes the process of preparing ceramic materials for absorption of acidic gases, mainly carbon dioxide, in exhaust systems and/or present indoors. Ceramic materials are formed by a mixture of alkali carbonate with alkaline earth metal oxide/hydroxide associated with a binding component, but non-limiting. The alkali carbonate comprises sodium, potassium carbonate, or a mixture of both. The alkaline earth metal oxide/hydroxide may be formed from magnesium oxide or magnesium hydroxide as well as calcium oxide and/or calcium hydroxide.

Abstract: A method of making an extruded granular absorbent is provided where the method includes providing an extruder and a starch-containing admixture, and pressurizing the starch containing admixture in the extruder under relatively high extrusion pressures to extrude the pressurized starch-containing admixture from the extruder, and producing a water absorbent and oil absorbent extrudate. The present invention further provides that the extruded granular absorbent may be combined with a non-extruded granular material with relatively high inert or cellulose content where there may be a greater proportion of extruded granular absorbent, and the extruded granular absorbent and non-extruded granular material agglutinate into a clump when wetted with water or urine.
