The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading. More particularly, a filtering zone is located in an upper portion of a reactor vessel above a rough liquid distribution tray and a distribution tray.

Certain embodiments include a screen assembly of a vessel, where the screen assembly includes a plurality of fixed elements and a retainer, and the retainer includes a ring, a plurality of wedges disposed about the ring, and a plurality of keyholes at spaced locations about the ring.

Each keyhole includes a bore and a slot extending from the bore into an adjacent wedge of the plurality of wedges, the slots have a width less than the bores, and the retainer may receive the fixed elements through the bores and may be rotated in a relation with the plurality of fixed elements to bring the plurality of fixed elements into simultaneous engagement with the wedges.

A process for the separation of electrolyte from the carbon in a solid carbon/electrolyte cathode product formed at the cathode during molten carbonate electrolysis. The processes allow for easy separation of the solid carbon product from the electrolyte without any observed detrimental effect on the structure and/or stability of the resulting solid carbon nanomaterial.

The invention relates to water purification devices of gravity type, intended for final purification of tap water and other liquids for household purposes.

From the state of the art water purification devices of gravity type usually consist of three elements: container for the raw liquid and container for purified liquid, which communicate with each other through water filtration cartridge. Raw liquid is poured into container for raw liquid and under gravity forces it flows through filtration cartridge and collects in the container for purified liquid. As it is known filtration cartridge consists of filtration zone and venting zone. Venting zone is executed as the lid with openings for raw liquid inflow and air outflow, and filtration zone. Filtration zone has in its bottom not less then one opening for purified water outflow and as usual is filled with filtration material. For example granulated and fibrous sorbents can be used as filtration materials in such purification devices.

Filtration cartridge of liquid purification device consists of filtration zone and venting zone, filtration zone in its turn consists of housing filled with the filtration material and not less than one opening made in the bottom of the housing, venting zone consists of fixation means and the lid, characterized in that filtration material has multi clustered interconnected structure, and venting zone is performed so as to retain and keep the main structure of the filtration material inside the housing of then filtration cartridge, by means of that fixation means is the first retention barrier and is made as a grid, the size of meshes of grid preferably is not more than average size of the filtration material cluster, and the lid is made as the second retention barrier and is made with the meshes which size is preferably not less than ten times less than size of the openings of the fixation means.
