A ceramic particulate filter having a porous catalytic material deposited on walls within the filter. Particulate matter is trapped in the walls of the filter and the catalytic material removes gases, such as nitrogen oxides (NOx), from gases passing through the filter. The filter, in one embodiment, is adaptable for use with internal combustion (gas and diesel) engines. A method of making the filter is also described.

This disclosure is directed to porous ceramic processing; and in particular to a method using selected pore forming materials to avoid high exotherms during the ceramic firing process, and the green bodies formed using the selected pore forming materials. The selected pore forming materials are homogeneous wax/non-ionic surfactant particles formed by a prilling process in which the wax is melted and the non-ionic surfactant is mixed into the wax prior to prilling. The disclosure is useful in the manufacture porous ceramic honeycomb bodies including ceramic honeycomb filter traps.

A microreaction device or system () includes at least one thermal control fluidic passage (C,E) and a principal working fluidic passage (A) with average cross-sectional area in the range of 0.25 to 100 mm, and having a primary entrance () and multiple secondary entrances () with the spacing between secondary entrances () having a length along the passage (A) of at least two times the root of the average cross-sectional area of the passage (A). The device or system () also includes at least one secondary working fluidic passage (B) having an entrance () and multiple exits () including a final exit (), each exit () being in fluid communication with a corresponding one of the multiple secondary entrances () of the principal fluidic passage (A).

High throughput thermally tempered microreactor devices and methods

A wall-flow honeycomb filter comprising a ceramic monolith having a plurality of porous walls formed therein. The plurality of porous walls define a plurality of inlet cells and a plurality of outlet cells extending between an inlet end face and an outlet end face of the monolith. The inlet cells are open at the inlet end face and plugged at or near the outlet end face. The outlet cells are open at the outlet end face and plugged at or near the inlet end face. The monolith has a ratio of a combined cross-sectional area of the inlet cells to a combined cross-sectional area of the outlet cells greater than 1. The monolith has at least one inlet cell cluster which contains an N&#xd7;M group of inlet cells, N and M being integers greater than 1, each inlet cell cluster consisting of a plurality of inlet cells separated by inlet cluster walls.

Wall-flow honeycomb filter having high storage capacity and low backpressure

Disclosed are washcoated ceramic honeycomb filters. The ceramic filters exhibit a relatively high level of washcoat loading while exhibiting minimized levels of backpressure. Also disclosed are methods for manufacturing the washcoated ceramic honeycomb filters. The method comprises providing an cell geometry derived from a predetermined level of washcoat loading to be applied to the ceramic honeycomb article.

Washcoat loaded porous ceramics with low backpressure

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.
