Technology for purе H2 production


Technology and equipment for extra-pure (99.9999 volume %) hydrogen production.


The technology allows to produce extra-pure gaseous hydrogen as a result of combustion of flammable hydrogen-containing materials (such as natural gas, coal, gasoline, alcohol, etc.). Figure 1 depicts the process to produce extra-pure hydrogen. The flow of hydrocarbons, such as gas, alcohol or gasoline, is supplied to the combustion chamber 1. The heat of combustion is mainly used to heat up water. Some minor quantity of the heat of combustion is used for heating of the hydrogen generator. Hydrogen being generated is supplied to the chamber 2 isolated from the combustion chamber. Then hydrogen is supplied to using equipment, for example, is puffed into the vacuum system. If it is necessary, hydrogen can be accumulated in a special storage unit (so called "compremator") based on intermetallic compound.


  • Hydrogen generator temperature:                                                300-700оС
  • Hydrogen generator capacity (at 700оС):                                     ~ 1 Ncm32)/s (3.6 l/hour)
  • Hydrogen purity degree:                                                              higher than 99.9999 volume percent
  • Pilot plant capacity:                                                                     5 – 500 liters/hour

Main Advantages

  • Extra-pure hydrogen is produced as hydrocarbon combustion co-product;
  • extra-pure hydrogen is generated in the course of single process;
  • low part of the main technological process power inputs to generate final product.

Areas of Application

for equipment to produce extra-pure Н2:

  • it is deemed advisable to adopt the suggested process for extra-pure hydrogen generation at enterprises where hydrocarbon raw materials are reclaimed (combusted) in large quantities, for example, at boiler houses or other hydrocarbon combustion facilities;
  • chemical-, electronic-industry enterprises;

for extra-pure hydrogen:

  • gas chromatograph detectors;
  • hydrocarbon analyzers;
  • laboratory plasma machines and plasmachemical reactors;
  • other analytic devices used by research and factory laboratories.

Stage of Development

  • Pilot laboratory plant, having capacity 1 Ncm32)/s (3.6 l/hour);
  • engineering concept of construction of 5-500 l/hour pilot plants for production of extra-pure hydrogen;
