Embodiment Construction

[0023] The method for preparing the carbon rod uniformly dispersed with catalyst particles in the present invention mainly adopts powder sintering technology. Powder sintering technology is to extrude catalyst metal powder and carbon powder into a mold with a specific shape, extrude the loose mixed powder into a powder, and then send the pressed powder into a high-temperature furnace for heating and sintering to make the powder The bodies are bonded together to form carbon rod products.

[0024] The present invention provides a kind of sintering equipment of carbon rod containing catalyst, which comprises: two half molds and a pressing device; the two half molds can cooperate to form a mold cavity, one end of which is closed and the other end is open; the pressing device can Extend into the mold cavity and cooperate with the two half molds.

[0025] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

Abstract

This invention involves the preparation method of a kryptol containing catalyst and its related sintering equipment. The sintering equipment consists of two half-dies and one clamping apparatus. The half-dies can be combined to form a full die with one end closed and another open. The clamping apparatus can be extended into the die and work with two half-dies. This invention also provides a method to prepare kryptol containing catalyst by this sintering equipment. This method can prepare kryptol with uniformly distributed particles of catalyst by powder sintering technology.

Description

【Technical field】 [0001] The invention relates to a preparation method of a catalyst-containing carbon rod and its sintering equipment. 【Background technique】 [0002] Carbon nanotubes are hollow carbon tubes first discovered in 1991 by Iijima in the product of arc discharge, which was published in Nature 354, 56 published in 1991. Carbon nanotubes have become a promising field emission cathode material due to their excellent electrical conductivity, perfect lattice structure, and nanoscale tip. They are used in fields such as field emission flat display devices, electric vacuum devices, and high-power microwave devices Has a broad prospect. [0003] The preparation methods of carbon nanotubes mainly include pulsed laser evaporation method, chemical vapor deposition method and arc discharge method. The pulse laser evaporation method is to use the high energy of the pulse laser to evaporate the graphite target containing the metal catalyst to obtain carbon nanotubes; the ch...
