DEVICE FOR TRAPPING MECHANICAL IMPURITIES AND DISTRIBUTING FLOW OF GAS-RAW MIXTURE AND METHOD FOR ITS MANUFACTURE Russian patent published in 2025 - IPC B01D46/10 B01D39/20 B01J33/00 

Abstract RU 2839629 C1

FIELD: performing operations.

SUBSTANCE: invention relates to a device for trapping mechanical impurities and distributing a flow of a gas-feed mixture. Device is a prefabricated structure made in the form of a hollow straight prism, the ribs of which are a metal frame holding the walls and bottom of the device, where said walls and bottom are made of filtering ceramic elements for trapping mechanical impurities and distributing the flow of the gas-feed mixture, and the upper base of said prism is made with possibility of passage through it of crude gas mixture flow, wherein said filtering ceramic elements are composed of multilayer hexagonal honeycombs with each layer shifted relative to another layer. Invention also relates to a method of making the device.

EFFECT: there are developed a device for trapping mechanical impurities and distributing a flow of a gas-feed mixture using 3D printing of ceramic filter elements and a method for its manufacturing, which provide effective trapping of mechanical impurities from the gas-feed mixture flow in catalytic process reactors of oil refining, increasing the contact surface of the gas-feed mixture with the front layer of the catalyst, which will make it possible to increase the duration of the catalyst operation in the reactor.
