Palladium membrane reduces the reaction temperature in methane and methanol steam reforming reactions, and increases the conversion rate of reactants and selectivity of target products in propane, isobutane, and ethylbenzene dehydrogenation reactions The use of palladium membrane in ammonia catalytic decomposition, water gas conversion, and removal of nitrate in water reactions has also achieved satisfactory results. Let's take a look belowPalladium membraneStructural classification:

1. Self supporting type: The self-supporting palladium membrane tube or membrane has a thickness of 15-100 microns and is generally made of palladium silver or palladium copper alloy. Mainly used for the separation of hydrogen gas, it can also be used for the separation of hydrogen isotopes and the separation between hydrogen isotopes.

2. Composite membrane: The disadvantages of self-supporting palladium membrane are poor strength, low permeability, and high cost. To solve this problem, palladium membranes are deposited on porous substrates to form supported palladium membranes (also known as palladium composite membranes or composite palladium membranes)

The above two aspects are an introduction to the structural classification of palladium membranes.
