cathodes for aluminum electrolysis cell with expanded

Optimization of the cathode block shape of an

A finite element/optimization model was developed to determine the optimum shape of the cathode block of an AP-30 aluminum electrolysis cell. The optimum shape is the design that makes the electric current density on the surface of the cathode block as uniform as possible so as to simultaneously prolong its lifetime, to minimize its energy consumption and to minimize the cost of material.

Is aluminium electrolysis using inert anodes a blind

An electrolysis technology may well have a lifetime of 50 years, but only if modifications are made during this period. One argument in favour of using inert anodes is to prevent the formation of perfluorocarbons (PFCs), which are a group of very powerful greenhouse gases.

Abstract: Cathodes for aluminum electrolysis cells are formed of cathode blocks and current collector bars attached to those blocks. The cathode slots receiving the collector bar are lined with expanded graphite lining thus providing longer useful lifetime of such cathodes and increased cell productivity.

Cathodes for Aluminum Electrolysis Cell with Expanded

[0024]It is accordingly an object of the invention to provide cathodes for an aluminum electrolysis cell with an expanded graphite lining, that overcomes the above-mentioned disadvantages of the prior art devices and methods of this general type.

Cathode

This is a cathode that is not heated by a filament. They may emit electrons by field electron emission, and in gas-filled tubes by secondary emission.Some examples are electrodes in neon lights, cold-cathode fluorescent lamps (CCFLs) used as backlights in laptops, thyratron tubes, and Crookes tubes..

Wettable Ceramic

The goal of the project was to develop the ceramic based materials, technology, and necessary engineering packages to retrofit existing aluminum reduction cells in order to reduce energy consumption required for making primary aluminum.

Aluminium smelting

Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Hroult process.Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be located close to large power stations, often hydro-electric ones, in

Hall–Hroult process

The density of liquid aluminum is 2.3 g/ml at temperatures between 950 and 1000 C. The density of the electrolyte should be less than 2.1 g/ml, so that the molten aluminum separates from the electrolyte and settles properly to the bottom of the electrolysis cell.
