OP-IV-9for <strong>the</strong> separation <strong>of</strong> super pure hydrogen from gaseous mixture. The program also includessearch effective new diffusive alloys and <strong>the</strong> development <strong>of</strong> optimal construction <strong>of</strong> <strong>the</strong>devices.Here are some characteristics <strong>of</strong> developed diffusive elements on base <strong>of</strong> compositemembranes including a selective filtering hydrogen membranes with 10 micron thickness.The special hydrogen filtering composite membrane at temperature <strong>of</strong> 550 °C, partialhydrogen pressure in <strong>the</strong> mixture <strong>of</strong>.0.6 MPa and <strong>the</strong> pressure <strong>of</strong> evolved hydrogen 0.15MPa sis equal to ~100 nm 3 H 2 /m 2 hour. For <strong>the</strong> developed diffusive elements <strong>the</strong> work temperatureis in <strong>the</strong> interval 400-700 °C.Presented below photos illustrated first construction decision <strong>of</strong> a composite filteringelement and also scheme for <strong>the</strong>ir testing in a laboratory reactor for production <strong>of</strong> sin-gasfrom methane.157
