Abstract
In one aspect, monolithic structural gas treatment bodies are described herein comprising a unique hierarchical pore structure and thin-walled honeycomb architecture in conjunction with high open area and sufficient size and mechanical strength for commercial and industrial applications, including carbon capture applications. As described further herein, the monolithic structural gas treatment body can exhibit a honeycomb structure wherein inner partition walls define longitudinal flow channels through the monolithic body.
Claims33
A monolithic structural gas treatment body comprising:
- an outer peripheral wall, and a plurality of inner partition walls having dispersed throughout a carrier comprising an inorganic oxide composition, the carrier comprising an hierarchical pore structure having a macroporosity of 0.24-1.0 cc/g in pores of diameter ranging from 600 to 50,000 Angstroms, and a mesoporosity of at least 0.17 cc/g in pores of diameter ranging from 20 to 300 Angstroms, wherein a total porosity of the carrier is at least 0.41 cc/g in pores of diameter ranging from 20-100,000 Angstroms, and the monolithic structural gas treatment body has the following structural features:
- (a) hydraulic diameter of at least 100 mm;
- (b) at least 85 cells per square inch (cpsi);
- (c) average thickness of the inner partition walls of 0.1 mm to 0.3 mm;
- (d) open frontal area of at least 65 percent;
- and
- (e) transverse compressive strength of at least 500 g/cm2.
