  • Patent number: 11547981
    Abstract: A method for producing a three-dimensional porous transition alumina catalyst monolith of stacked catalyst fibers, comprising: a) Preparing a paste in a liquid diluent of hydroxide precursor particles and/or oxyhydroxide precursor particles of transition alumina particles, all particles in the suspension having a number average particle size in the range of from 0.05 to 700 ?m, b) extruding the paste nozzle(s) to form fibers, and depositing the extruded fibers to form a three-dimensional porous catalyst monolith precursor, c) drying the precursor to remove the liquid diluent, d) performing a temperature treatment of the dried porous catalyst monolith precursor to form the transition alumina catalyst monolith, wherein no temperature treatment of the porous catalyst monolith precursor or porous catalyst monolith at temperatures above 1000° C. is performed and wherein no further catalytically active metals, metal oxides or metal compounds are applied to the surface.

  • Patent number: 11439995
    Abstract: A three-dimensionally structured porous catalyst monolith of stacked catalyst fibers with a fiber diameter of less than 1 mm made from one or more continuous fibers or stacked individual fibers, wherein the stacked catalyst fibers are arranged in a regular, recurring stacking pattern of fiber layers to form the three-dimensionally structured monolith, and wherein in each of the stacked fiber layers at least 50 wt % of the fibers are arranged parallel to each other and spatially separated from each other, or in a cobweb pattern, and wherein the side crushing strength of the monolith is at least 60 N.
