Platform parameters carry out data record, and parameters are adjusted as needed at any time.
8. the membrane tube test platform according to claim 2 for hydrogen purification, it is characterised in that:
The hydrogen filtration system further includes microparticle filter；Pure hydrogen after purification passes through methanation converter, hydrogen filtration
Device, microparticle filter further purify hydrogen；
The effect of the microparticle filter is small in the particle filtering and methanation converter that can not observe naked eyes
Grain filters out.
9. the test method described in a kind of one of claim 1 to 8 for the membrane tube test platform of hydrogen purification, feature exist
In,
The test method includes the following steps:
The temperature of membrane tube heating mantle is set by host computer；
After membrane tube temperature reaches requirement, hydrogen-rich gas is entered film after hydrogen flowmeter adjusts flow by hydrogen-rich supply system
Pipe purification system is purified；
Hydrogen after purification is further purified by methanation converter and hydrogen filter, purified hydrogen connection
Gas-chromatography carries out purity detecting.
