Preparation of specially pure hydrogen at 500–700°C from methane in high-temperature converter-membrane equipment, combined with a CH4 conversion catalyst

The possibility is confirmed by calculation of reducing the operating temperature of a high-temperature converter-membrane system, combined with a CH4 conversion catalyst, from 800 to 700–600°C with an insignificant reduction in technical and economic indices, but with the additional possibility of expanding the choice of membrane and structural materials, including palladium alloy V-1 highly recommended in practice. Results of quantitative evaluation of high-temperature converter-membrane system parameters are in good agreement with published data for a membrane converter.
