  • Patent number: 5215690
    Abstract: A method of forming an activated carbon or graphite structure is provided by (1) forming, such as extrusion, of a plasticized mixture of: binder selected from cellulose ether and derivative thereof, starch, and mixture thereof; furfuryl alcohol and/or polyfurfuryl alcohol; and carbon, graphite, or a carbon-containing material; and (2) subjecting the formed mixture to a carbon-forming pyrolysis step. The use of furfuryl alcohol allows extrusion at ambient temperatures and provides a "reactive" solvent that provides carbon upon pyrolysis.
    Type: Grant

  • Patent number: 4631267
    Abstract: A catalyst support having both substantial high strength and high surface area can be produced by heating a shaped mixture of a porous oxide having a surface area of at least 20 m.sup.2 /g and the precursor of an inorganic binder for the porous oxide. The binders are precursors of alumina, silica, or titania, and are capable of imparting substantial strength to the support at relatively low firing temperatures.

  • Patent number: 4631268
    Abstract: A method of forming a monolithic ceramic catalyst support having a high surface area phase of porous oxide embedded within the monolith structure is provided. The porous oxide phase is incorporated into a sinterable ceramic structure as a discrete discontinuous phase. The high surface area necessary for effective catalyst support is thereby provided within the ceramic structure, which is sintered to provide appreciable density and strength.

  • Patent number: 4631269
    Abstract: Monolithic catalyst support structures in which a support phase of high surface area oxide material is disposed on or within a sintered ceramic material are improved by using a mixture of alumina and silica as the high surface area oxide support phase. The mixtures of alumina and silica retain higher surface area, after firing or exposure to elevated service temperatures, than does either component individually, and thereby impart higher overall surface area to the monolithic support structures.

  • Patent number: 4532228
    Abstract: This invention is concerned with the production of catalyst-coated, ceramic honeycomb structures wherein the ceramic contains microcracks and wherein a washcoat is applied to the honeycomb structures prior to the application of the catalyst. The invention contemplates depositing an organic material in the microcracks and, preferably, carbonizing said organic material prior to application of the washcoat, and which is burned out after application of the washcoat.

  • Patent number: 4018614
    Abstract: Mismatched expansions of monoclinic celsian and zirconia crystals and the refractoriness of both phases in a sintered ceramic body result in highly refractory, microcracked and thermal shock resistant products. Avoidance of the higher expansion hexagonal form of celsian is desirable to obtain the better thermal shock resistance.
