  • Publication number: 20190367416
    Abstract: Sintered product having a relative density of greater than 90%, with, to more than 80% of the volume thereof, a stack of flat ceramic platelets, the assembly of the platelets having a mean thickness of less than 3 ?m, having a width of greater than 50 mm, and including more than 20% of alumina, as a percentage on the basis of the weight of the product. The width of the product is the largest dimension measured in the plane in which the length of the product is measured, along a direction perpendicular to the direction of the length. The length of the product is the largest dimension thereof in a plane parallel to the general plane in which the platelets extend.

  • Publication number: 20180215667
    Abstract: Sintered product having a chemical analysis such that, in mass percentages: SiO2 content is greater than 0.2% and less than 2%, and CaO content is greater than 0.1% and less than 1.5%, and MgO content is less than 0.3%, and alumina and other elements being the complement at 100%, the content of other elements being less than 1.5%, having a relative density greater than 90%, comprising, for more than 90% of its volume, a stack of ceramic platelets (10) laid flat, all of said platelets having an average thickness less than 3 ?m, more than 95% by number of said platelets each containing more than 95% by mass of alumina, having a width (l) greater than 81 mm.

  • Publication number: 20130071610
    Abstract: Product formed from a ceramic material, at least part of the product not being formed from amorphous silica, having pores and satisfying the following criteria: (a?) at least 70% by number of the pores are tubular pores extending substantially parallel to each other in a longitudinal direction; (b?) in at least one cross-section plane, at least 30% by number of the pores have a section of convex hexagonal shape, these pores being known hereinbelow as “hexagonal pores”, at least 80% by number of the hexagonal pores having a roundness index of greater than 0.70, the roundness index being equal to the ratio SA/LA of the lengths of the small and long axes of the ellipse in which the section is inscribed; the mean size of the cross sections of the pores is greater than 0.15 ?m and less than 25 ?m.

  • Patent number: 6824749
    Abstract: Methods and apparatus for treating a gas-liquid feed stream with structured monolithic catalysts of honeycomb configuration wherein the catalysts are configured as a stack of honeycomb sections with offset channels, the resulting channel dislocations between adjacent contacting honeycombs in the stack introducing controlled, limited turbulence and mixing of feed stream portions traversing the channels to significantly increase the catalytic efficiency of the reactor.
