Today, one of the most widespread processes in modern oil refining is the production and purification of hydrogen, which is used in the production of ammonia, methanol, and plastics. Without it, the production of high-quality motor fuels is impossible, since this gas is involved in the hydrogenation process (hydrotreating) [1].
Currently, at oil refineries and petrochemical plants, hydrogen is obtained in two ways: from natural gas by steam reforming into a mixture of hydrogen and carbon monoxide (synthesis gas), in a catalytic reforming unit, where a mixture of hydrogen and light hydrocarbon gases (hydrogen-containing gas) is released. Most modern oil refineries have a hydrogen production unit, its widespread use in industry is explained by its chemical activity, ease of production and high exothermicity of the process [2].
