  • Graphene-ceramic composite membrane for hydrogen separation membranes
    Patent number: 10899613
    Abstract: A hydrogen permeation membrane is provided that can include a carbon-based material (C) and a ceramic material (BZCYT) mixed together. The carbon-based material can include graphene, graphite, carbon nanotubes, or a combination thereof. The ceramic material can have the formula BaZr1-x-y-zCexYyTzO3-?, where 0?x?0.5, 0?y?0.5, 0?z?0.5, (x+y+z)>0; 0???0.5, and T is Yb, Sc, Ti, Nb, Ta, Mo, Mn, Fe, Co, Ni, Cu, Zn, Ga, In, or a combination thereof. In addition, the BZYCT can be present in the C-BZCYT mixture in an amount ranging from about 40% by volume to about 80% by volume. Further, a method of forming such a membrane is also provided. A method is also provided for extracting hydrogen from a feed stream.

  • Direct synthesis of hydrocarbons from co-electrolysis solid oxide cell
    Patent number: 10662383
    Abstract: A method for generating hydrocarbons using a solid oxide electrolysis cell (SOEC) and a Fischer-Tropsch unit in a single microtubular reactor is described. This method can directly synthesize hydrocarbons from carbon dioxide and water. The method integrates high temperature co-electrolysis of H2O and CO2 and low temperature Fischer-Tropsch (F-T) process in a single microtubular reactor by designation of a temperature gradient along the axial length of the microtubular reactor. In practice, methods disclosed herein can provide direct conversion of CO2 to hydrocarbons for use as feedstock or energy storage.
