The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors comprise a precursor alumina blend capable of enhancing one or more properties of a shaped porous body based thereupon. The need to employ modifiers to achieve a similar result may thus be substantially reduced, or even avoided, and cost savings are thus provided, as well as savings in time and equipment costs.

The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors, comprise one or more topography-enhancing additives, i.e., additives that are capable of at least marginally enhancing one or more of surface area, aspect ratio, pore volume, median pore diameter, surface morphology, etc. Downstream products need not necessarily comprise the topography-enhancing additives in order to exhibit the benefits of their inclusion in the porous body precursors.

A method of preparing a gelled ceramic-based foam comprising forming a slurry comprising at least water, a ceramic, albumin and an aldehyde, such that the ratio of the aldehyde to the albumin is from about 60:1 to about 200:1, and frothing the slurry, such that the albumin polymerizes to form a gelled ceramic-based foam. The foam shows improved capability to resist collapse during any subsequent handling, drying to greenware, or firing steps. This enables simplified and more economical production of highly porous ceramics.
