Abstract:
A method for the production of ammonia, comprising the steps of:(a) generating a reducing gas; (b) generating steam; (c) contacting said reducing gas with a first metal oxide in a first reaction zone to reduce said first metal oxide to a first metal; (d) contacting said steam with a molten metal pool including a second metal and contained in a second reaction zone to oxidize said molten second metal to a second metal oxide and form a first hydrogen gas stream; (e) extracting said first hydrogen gas stream from said second reaction zone; (f) contacting said reducing gas with said second metal oxide in said second reaction zone to reduce said second metal oxide to a second metal; (g) contacting said steam with said first metal in said first reaction zone to oxidize said first metal to a first metal oxide and form a second hydrogen gas stream; (h) extracting said second hydrogen gas stream from said first reaction zone; and (i) reacting at least one of said first and second hydrogen gas streams with nitrogen gas to form ammonia.
