Design of oxygen and hydrogen separation membranes is the point of current interest in producing syngas from biofuels. Nanocomposites with a high mixed ionic-electronic conductivity are known to be promising materials for these applications. This work aims at studying performance of oxygen and hydrogen separation membranes based on nanocomposites PrNi0.5Co0.5O3-delta + Ce0.9Y0.1O2-delta and Nd(5.5)WO1(1.25-delta) + NiCu alloy, respectively. A high and stable performance promising for the practical application was demonstrated for these membranes. For oxygen separation membrane CH4 conversion is up to 50% with H-2 content in the outlet feed being up to 25% at 900 degrees C. For reactor with hydrogen separation membrane complete EtOH conversion was achieved at T similar to 700 degrees C even at the highest flow rate, and a high hydrogen permeation (>= 1 ml H-2 cm(-2) min(-1)) was revealed.
