SU109592A1 - Reactor for hydrogenation and hydrotreatment of basket loaded catalyst fuels - Google Patents

Description

Substantial catalytic hydrogenation and hydrotreatment of FUEL require zone supply of cold gas to remove 3fold heat of reaction, positioning of the catalyst along the height of the reactor, mixing hot and cold gas and vapor streams and periodically replacing the catalyst with its unloading and loading using powerful goat cranes.

The present invention eliminates the use of gantry cranes, provides optimal conditions for the process and allows for a time-consuming operation of unloading and loading the reactor with a catalyst using conveyor-type cranes with a lifting capacity of up to 5 tons.

The reactor has a cylindrical body / (see drawing), made of thick-step sheet steel. From above, the reactor vessel has a flat lid 2. Inside the vessel is covered with thermal insulation 3, which is separated from the internal device

reactor perforation of thin-walled glass 4.

Along the axis of the reactor, 5 is installed to provide input of the product and output of the reaction products and gases. In the lower part, the reactor has a support grid b, which is installed on metal support structures in the form of a perforated metal cylinder 7.

Inside the reactor are placed over the other basket 8 with a catalyst 9. The basket is a hollow metal cylinder having an outer and an inner wall with a hollow through hole in the middle for the passage of the central tube. At the bottom, the basket has a grid 10, under which there are slit openings for gas inlet, a mixing diaphragm 11 and a mixing grid 12 are mounted below the slots. The lower basket does not have a mixing diaphragm and a mixing grid :. Through all the baskets down to the bottom of the reactor, two pockets J3 for installing thermocouples are passed.

To prevent the catalyst from spilling from the baskets when they are unloaded from the reactor, a valve is installed on the outer wall of the mixing grid.

In order to prevent the penetration of hot gas and product vapors into the gaps in the outer wall of the basket and the outer wall of the central tube and to ensure the required density, between the landing pieces of the baskets there are asbestos printed cords 14.

Hot gases and vapors are flushed through the nozzle located at the top of the reactor, but the input and output of the gases and vapors of the product can also be carried out through the bottom of the reactor, as shown in the drawing.

  The baskets can be lowered into the reactor with loaded catalyst IDs empty and then loaded with a catalyst with a telescopic tube.

The catalyst was unloaded with a basket, mixed with my diaphragm and mixing grid.

Subject invention

A reactor for the process of hydrogenation and hydrotreatment of basket-loaded catalyst fuels, characterized in that to ensure reliable loading and unloading of baskets with a catalyst, a central pipe is used to pass the cable and pass through the bottom cover of the reactor.
