Improving the POM performance of YBa2Cu3O7−δ membrane reactor by Co doping

The performance of Co doped YBa2Cu3O7−δ (YBCO) membrane reactor have been investigated in a process of the partial oxidation of methane (POM) to syngas. The results shows that doping YBCO membrane with a little Co can enhance its oxygen permeation flux and improve its stability in reducing atmosphere noticeably. At 900 °C, with feed flow at 50 ml/min, CH4 6.0 v%, SV = 12,000 h−1, and Ni/ZrO2 catalyst, CH4 conversion rate, CO selectivity, and oxygen permeation flux can reach to 98%, 92% and 1.41 ml min−1 cm−2 respectively.
