Highly effective NO decomposition by in situ removal of inhibitor oxygen using an oxygen transporting membrane

Abstract

Due to the in situ removal of the inhibitor oxygen using an oxygen transporting membrane, a complete conversion of NO to N(2) was achieved for the first time in a catalytic perovskite membrane reactor.

Study of the Transport Properties of the Mixed Ionic Electronic Conductor Ce1−xTbxO2−δ + Co (x = 0.1, 0.2) and Evaluation As Oxygen-Transport Membrane

“…The current state of technology development for ASU applies high energy consuming cryogenic distillation units while alternative oxygen separation technologies such as ion transport membranes [2] would enable thermal integration and energy savings. Furthermore, several chemical processes [3,4,5,6,7] would benefit from the development of highly-permeable and CO 2 stable ceramic membranes, since it would make possible the process intensification and the improvement of product selectivity by avoiding the direct contact of molecular oxygen and reaction products.…”

A novel porous‐dense dual‐layer composite membrane reactor with long‐term stability

“…[1][2][3] Dense mixed ion-electronic conducting (MIEC) materials, with great oxygen ionic and electronic conductivities at high temperatures have attracted considerable interests in many applications such as effective utilization of natural gas [4][5][6][7][8][9][10][11][12][13] or coke oven gas, 14,15 production of hydrogen, [16][17][18] selective oxidation of light hydrocarbons to high-added-value-chemicals [19][20][21][22] , and treatment of atmospheric pollutants, expecially CO 2 and NO X . 11,[23][24][25] MIEC membrane reactors can overcome many of the shortcomings of conventional packed-bed reactors. For example, it controls distribution of oxygen and improves the selectivity or heat-distribution in the reaction side under partial oxidation of methane (POM).…”

Dense ceramic oxygen permeable membranes and catalytic membrane reactors

“…In this membrane reactor, we also investigated the NO decomposition in a similar process [217]. An almost 100% NO conversion and 95% N 2 yield was achieved at 875°C.…”

“…In order to avoid the negative effect, we conducted the N 2 O decomposition in the OPM reactor based on BCFZ (Fig. 18) for the first time [216,217]. N 2 O can be decomposed on the OPM surface with the catalysts firstly according to N 2 O ?…”
