LINE REGENERATION recycle zeolite-containing catalyst ennobling virgin petrol fractions

摘要

The line is designed to restore the activity of zeolite catalyst by oxidative regeneration in a stream of nitrogen-oxygen mixture with recycled flue gas from the regeneration unit, and can be implemented in oil and gas companies for production of high octane components of motor fuels with improved environmental characteristics. The line comprises a vessel for otregenerirovannogo catalyst, as well as four to six reactor units and regeneration node located at different elevations. In this container with otregenerirovannym catalyst located above the reactor units and the regenerator located below the reactors. Reactor assemblies associated with a single regeneration unit and configured to pass a catalyst therethrough by gravity under the action of gravity. For this purpose, each reactor receiving hopper associated with the regeneration node, and each node receiving hopper associated with the reactor vessel for otregenerirovannogo catalyst in which the catalyst is fed from the regenerator transport katalizatoroprovodom, providing the possibility of controlled movement catalyst. The scheme provides for return to the regenerator portion of the coke oxidation off-gases, thereby reducing the environmental load by reducing the amount of incomplete combustion products and more fully restore the activity of regenerated catalyst.
