THE OVERARCHING GOAL OF THIS PROJECT IS TO CREATE A NOVEL, RESILIENT, SCALABLE, ACTIVE, AND SELECTIVE CARBON MEMBRANE REACTOR (CMR) POWERED BY NON-FOSSIL FUEL FOR DECARBONIZED C3H6 AND H2 PRODUCTION FROM PROPANE DEHYDROGENATION (PDH). THE REACTOR SYSTEM CONSISTS OF THREE KEY INNOVATIONS, A ZEOLITE CONFINED METAL NANOCLUSTER CATALYST FOR LOW-TEMPERATURE C3H8 ACTIVATION, A CARBON HOLLOW FIBER MEMBRANE FOR CONVERSION ENHANCEMENT BY IN SITU H2 SEPARATION, AND JOULE-HEATING OF THE CMR. THE OBJECTIVES OF THIS PROJECT ARE TO 1) OPTIMIZE M/ZEOLITE CATALYSTS FOR LOW-TEMPERATURE C3H8 ACTIVATION AND PROVIDE KINETIC MODELS FOR CATALYST/REACTOR OPTIMIZATION; 2) DEVELOP AND SCALE UP NOVEL ARAMID-DERIVED CARBON HOLLOW FIBER MEMBRANES FOR H2 SEPARATION AND INVESTIGATE THEIR JOULE HEATING PROPERTIES, ESTABLISH STRUCTURE-PROPERTY-PERFORMANCE CORRELATIONS; 3) DEVELOP THERMAL MANAGEMENT PROTOCOLS AND UNDERSTAND THE NATURE OF TEMPERATURE CONTROL SYSTEMS; AND 4) DESIGN, DEVELOP, AND TEST 1-10 KW PROTOTYPE CMR SYSTEMS AS WELL AS CONDUCT ENERGY EFFICIENCY, TECHNO-ECONOMIC, AND LIFE-CYCLE ANALYSES FOR SCALING-UP. AT THE END OF THIS PROJECT, WE AIM TO DEMONSTRATE AND PROVIDE FOUNDATIONAL UNDERSTANDING FOR A PROTOTYPE 10 KW CMR WITH ZERO CO2 EMISSION, WHICH WILL RUN AT 400-500°C AND 1-10 BAR WITH SINGLE-PASS C3H8 CONVERSION =45%, C3H6 SELECTIVITY = 98%, C3H6 PRODUCT FLOW RATE =0.055 KG H-1 (NOTE: AREAL RATE WILL BE 0.22 KG H-1 M-2 MEMBRANE REACTOR AREA) FOR A LIFETIME OF =500 H.
