Abstract

The invention discloses a hydrogen recovery method of a methane catalytic cracking instrument. The hydrogen recovery method comprises the following steps: S1, a device is calibrated through a standard gas inlet; S2, nitrogen is introduced through a nitrogen inlet to purge the interior of the device, and air and impurities in the device are discharged; S3, combustible gas is introduced through a hydrogen inlet and a methane inlet; S4, the combustible gas is mixed in a mixing tank, and carbon nanotubes and hydrogen are generated through reaction; and S5, hydrogen generated by the reaction and combustible gas serving as a raw material selectively enter a gas chromatograph and a hydrogen recovery assembly through a four-way valve. Not only can hydrogen be collected, but also redundant methane in tail gas can be recycled. The problems of low hydrogen recovery rate and low purity in the methane catalytic cracking process are solved.

Description

technical field [0001] The invention belongs to the technical field of methane catalysis, and in particular relates to a hydrogen recovery device for a methane catalytic cracker. Background technique [0002] The invention and production of carbon nanotubes has greatly promoted the development of natural science and technology in the world, which has epoch-making significance. Carbon nanotubes, also known as bucky tubes, can be considered structurally as a tubular structure in which the basic unit formed after graphene is curled is a regular hexagon. Its radial dimension is on the order of nanometers, with a typical diameter of 2-100nm, its axial dimension is on the order of microns, and its length can reach several microns to tens of microns. Material. In practice, it has the characteristics of light weight and rich physical and chemical properties. It is not only a popular new material in cutting-edge technology fields such as aerospace, but also an ideal electrode mater...
