b'Continuous syngasNovel chemical looping process combats climate change production from a newby converting the greenhouse gases methane and carbon chemical looping concept todioxide into valuable industrial feedstock.balance power dynamics inS yngas, a mixture of carbon monoxide and hydrogen, is an extremely important industrial feedstock used to manufacture more valuable fuels integrated energy systems and chemicals. Industrial and commercial syngas production from steam methane reforming process requires large scale, centralized production capacities and a continuous, energy-intensive heat supply (1000C) to accommodate economies of scale. This investigation of a chemical looping process using carbon dioxide as an oxidant demonstrated feasibility that could revolutionize distributed syngas production as it enables a low-cost, low temperature process in a modular reactor that offers inherent flexibility. Chemical looping syngas production is a PROJECT NUMBER: two-step reduction-oxidation cycle with oxygen carriers (metal oxides) alternating21P1064-031FP between oxidized and reduced states. A decrease in the oxide reduction temperature TOTAL APPROVED AMOUNT:while retaining high reactivity toward carbon dioxide splitting was demonstrated $160,000 over 2 years in this work by combining methane reforming with nickel supported on a ceria-zirconia solid solution material. A compelling feature of this distinct looping process PRINCIPAL INVESTIGATOR:is the continuous production of syngas from both reduction and reoxidation cycles Rebecca Fushimi during the chemical looping process at much lower temperatures (500-700C). CO-INVESTIGATORS: Carbon deposits formed during methane reforming were found to be beneficial by Debtanu Maiti, INL maintaining ceria in a reduced state, thereby increasing the reduction capacity and Yixiao Wang, INL efficiency of each chemical looping cycle. By understanding the reduction-oxidation properties of the catalyst through dynamic catalyst science using the Temporal COLLABORATORS: Analysis of Products reactor, more advanced reaction strategies were devised to North Carolina State University control carbon formation while maintaining material stability and exploiting kinetics University of Maine for optimal performance.Schematic of the chemical looping process over a mixed metal oxide catalyst (M x O y ). In the first step, methane (CH 4 ) is partially oxidized with lattice oxygen from the catalyst to produce syngas (carbon monoxide (CO) and hydrogen (H 2 )), which in turn reduces the catalyst. CH 4decomposition can also deposit carbon (C) on the catalyst surface. In the second step, an oxidant, carbon dioxide (CO 2 ) or water (H 2 O), replenishes catalyst lattice oxygen and gasifies surface C into syngas, 84 returning the catalyst to its starting state.'
