INCREASE IN THE EFFICIENCY OF PREPARING SPECIALLY PURE HYDROGEN FROM METHANE IN A HIGH-TEMPERATURE CONVERTER-MEMBRANE EQUIPMENT SYSTEM

摘要

The possibility is analyzed of preparing specially pure hydrogen (SPH) in a high-temperature converter-membrane equipment system drawing on model representations developed previously using heat-resistant palladium alloys. Dependences are calculated for the parameters of membrane separation of methane steam catalytic conversion products on membrane area with different ratios of C_(H_2O)/C_(CH_4) in the starting material. The high efficiency of preparing SPH is demonstrated, i.e., of the order of 1.28 m~3 per cubic meter of starting gas.
