Technology of hydrogen production from natural gas
The technology uses natural gas to undergo a chemical reaction with water vapor in a special reformer filled with a catalyst after pressurized desulfurization to generate a converted gas containing hydrogen, carbon dioxide and carbon monoxide. After part of the heat is recovered by the waste pot, CO in the converted gas is converted into H?, and the converted gas is purified by pressure swing adsorption (PSA) after cooling and condensing gas-liquid sharing.
■Technical features
Mature production technology, safe and reliable operation.
The operation control is safe and practical, and the degree of automation is high.
Low operating costs and short payback periods.
PSA analytical gas can be burned back, which not only reduces fuel consumption, but also reduces exhaust emissions.
■ Reaction principle
CH4 H2O→3H2 CO-Q
What H2O→H2 CO2 Q
■ Main performance indicators
Unit size: 100 ~ 200000nm ³/h
Purity: 99% ~ 99.999
Pressure: 0.8 ~ 2.5MPa

Pressure swing adsorption hydrogen extraction device
After the mixed gas containing hydrogen (H₂) enters the adsorption tower of pressure swing adsorption (PSA) device, because the adsorption capacity of the adsorbent in the adsorption bed for each component in the gas mixture varies with the pressure change, the impurities in the feed gas are adsorbed during pressurization, and the components (hydrogen) that are not easily adsorbed are output as products from the outlet end of the adsorption bed. During decompression, the adsorbed impurities are desorbed and the adsorbent is regenerated at the same time, at least four adsorbent bed cycles are used to operate to achieve a continuous output of product hydrogen.
VPSA pressure swing adsorption oxygen plant
Multi-tower combined VPSA pressure swing adsorption oxygen production technology is a new process with low energy consumption, low noise and low maintenance cost. It has been accepted by the first set of devices in Zhejiang Province and is widely used in non-ferrous smelting, glass smelting, iron and steel smelting, chemical industry, paper making and other industries.
