Claims (1)

Известный способ получени  водор да состоит в конверсии окиси углеро да в присутствии низкотемпературного катализатора. Однако при этом степень превращени  окиси углерода недостаточна. Предлагаетс  конверсию окиси уг .лерода осуществл ть в в присутствии низкотемпературного катализатора и кислорода, вводимого в количестве лучше 0,2-0,5% в конвертируемый газ при остаточном содержании окиси углерода 0,1-1%. Это позвол ет снизить содержание остаточной окиси углерода до 0,03-0,05% и повысить выход водорода. Способ состоит в том, что на завершающем этапе конверсии с вод ным паром при остаточном содержании оки си углерода 0,2-0,6% в реакционную смесь, охлажденную до 100-200°С и доведенную до отношени  пара и газа 0,1-1, ввод т 0,2-0,5% кислорода, по ле Чего смесь направл ют в реакционный объем с низкотемпературным катализатором . Перед конверсией с введением кислорода желательна очистка конвертированного газа от СО2. Указанный процесс, можно проводить как при атмосферном, так и при повышенном давлении (до 60 ат и выше). Пример . Черезреактор, загруженный 15 см цинкхроммедного низкотемпературного катализатора, пропускают газовую смесь состава, %: N2 19; В 2 59,5; СО 20; СО 0,6; О2 0,4; СН4. 0,5. При этом отношение пара и газа менее 0,1, а остаточное содержание окиси углерода в интервале температур 120-200°С 0,05%. Формула изобретени  1.Способ получени  водорода конверсией окиси углерода на низкотемпературном катализаторе, отличающийс  тем, что, с целью повышени  степени превращени  окиси углерода и увеличени  выхода водорода , конверсию окиси углерода осуществл ют в присутствии кислорода, вв одимого в реакционную смесь при остаточном содержании окиси углерода 0,1-1%;A known method for producing hydrogen consists in the conversion of carbon monoxide in the presence of a low-temperature catalyst. However, the degree of conversion of carbon monoxide is insufficient. Carbon monoxide conversion is proposed to be carried out in the presence of a low-temperature catalyst and oxygen introduced in an amount better than 0.2-0.5% into a convertible gas with a residual carbon monoxide content of 0.1-1%. This allows reducing the content of residual carbon monoxide to 0.03-0.05% and increasing the yield of hydrogen. The method consists in the fact that at the final stage of the conversion with water vapor with a residual content of carbon monoxide of 0.2-0.6% into the reaction mixture cooled to 100-200 ° C and brought to a ratio of steam and gas 0.1- 1, 0.2-0.5% oxygen is introduced, after which the mixture is sent to the reaction volume with a low-temperature catalyst. Before the conversion with the introduction of oxygen, it is desirable to clean the converted gas from CO2. This process can be carried out both at atmospheric and at elevated pressure (up to 60 at and above). An example. A gas mixture of the following composition is passed through a reactor loaded with 15 cm of a low-temperature synchromo-catalytic catalyst,%: N2 19; B 2 59.5; WITH 20; WITH 0.6; O2 0.4; CH4. 0.5 The ratio of steam and gas is less than 0.1, and the residual content of carbon monoxide in the temperature range of 120-200 ° C is 0.05%. Claim 1. Method for producing hydrogen by conversion of carbon monoxide on a low-temperature catalyst, characterized in that, in order to increase the conversion of carbon monoxide and increase the yield of hydrogen, carbon monoxide is converted in the presence of oxygen into the reaction mixture with a residual content of carbon monoxide 0.1-1%;
