A method for facilitating the distribution of the flow of one or more streams within a bed vessel is provided. Disposed within the bed vessel are internal materials and structures including multiple operating zones. One type of operating zone can be a processing zone composed of one or more beds of solid processing material. Another type of operating zone can be a treating zone. Treating zones can facilitate the distribution of the one or more streams fed to processing zones. The distribution can facilitate contact between the feed streams and the processing materials contained in the processing zones.

A mould for manufacturing a packing member from a liquid ceramic composition. The mould including a first part and a second part, wherein the first part and/or the second part comprise an open mould cavity and wherein the first and second parts are operable to engage to form a closed mould cavity, wherein the mould further includes a reservoir forming member, and wherein the mould is operable to be moved from an open position in which the first and second parts are at least partially spaced such that the reservoir member forms a reservoir cavity and the mould cavity is open, to a partially closed position in which the location of the reservoir cavity has moved with respect to the mould cavity and/or the volume of the reservoir cavity has reduced, and then to a closed position in which the first and second parts are engaged such that the mould cavity is closed.

Assemblies, apparatuses, systems, and method to extract or convey a material from a source of the material may include a vacuum generation and sound attenuation assembly to enhance conveyance the material from the source of the material. The vacuum generation and sound attenuation assembly may include a vacuum source including a plurality of vacuum generators. Each of the plurality of vacuum generators may be positioned to cause a vacuum flow between the source of the material and the vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may further include a sound attenuation chamber connected to the vacuum source. The sound attenuation chamber may include an attenuation housing at least partially defining a chamber interior volume being positioned to receive at least a portion of the vacuum flow from the vacuum source and attenuate sound generated by the vacuum source.

The invention relates to the development of a carrier material providing high surface area for biofilm formation in wastewater treatment plants and a carrier material surface modification method for accelerating and enriching biofilm formation.

The present disclosure relates to a packing element, in particular for mass and/or heat exchange columns, through which at least one gas and/or at least one liquid flow flows, comprising a plurality of neighbouring strips curved inwards and/or outwards, wherein each strip is connected to the neighbouring strips at at least one end thereof. It is the object of the present invention to provide a packing element that is improved relative to the state of the art. According to the disclosure, this object is achieved in that at least one of the strips has an irregular shape.

The invention relates to a method for producing a pellet, in particular for a catalytic convertor and/or static mixer. The method comprises a trimming and/or deforming of at least one layer of metal foam material into a pellet shape.

A method for isomerising dehydration in the presence of a specific catalyst, to produce at least one alkene, carried out on a feedstock containing a non-linear primary monoalcohol, where the catalyst includes a zeolite having a series of 8MR channels and a binder having certain pore volume, which catalyst is multilobe-shaped and has characteristics including certain average mesopore volume Vm, and mesopores having a certain diameter, an average certain macropore volume VM, the macropores having a certain diameter, and certain average micropore volume Vμ, the micropores having a certain diameter, and the catalyst has a certain exposed geometric area.

A method of carrying out the dehydrogenation of lower alkanes in a fixed-bed reactor containing a catalyst bed, the catalyst bed comprising (i) catalyst particles supporting a catalyst effective to promote said dehydrogenation and (ii) engineered inert diluent particles, where the method comprises passing the lower alkane in gaseous form through the catalyst bed, wherein the engineered inert diluent particles have a cross-sectional shape having two opposing convex edges joined by and intersecting two opposing concave edges, and a plurality of holes between said edges penetrating through the particle.

A catalytic system is provided which comprises a tubular reactor and at least one catalyst particle located within the tubular reactor. The catalyst particles have a particular geometric form which promotes heat transfer with the tubular reactor. Certain specific catalyst particles are also provided.
