Abstract

In this study, a continuous flow of a synthetic, dry, and acidic waste synthesis gas (WSG) (containing N 2 , H 2 , CO, CH 4 , and CO 2 ) at ambient temperatures was first passed through a fixed bed reactor (FBR) containing halite + m-Fe 0 and then a saline bubble column diffusion reactor (BCDR) containing m-Fe 0 . The FBR converted 47.5% of the CO + CH 4 + CO 2 into n-C 0 . Passage of the n-C 0 into the BCDR resulted in the formation of the desalination catalyst (Fe 0 :Fe(a,b,c)@C 0 ) + CH 4 + CO + CO 2 + C x H y , where 64% of the feed n-C 0 was converted to gaseous products. The desalination pellets can remove >60% of the water salinity without producing a reject brine or requiring an external energy source. The gaseous products from the BCDR included: C x H y (where x < 6), CO, CO 2 , and H 2 .
