Abstract:
1. A method of providing steam and absorbing CO 2 for H 2 production using a water gas shift reaction in a water gas shift reactor comprising: contacting a first gaseous stream comprising CO and CO discharging the second gaseous stream from the first absorption reactor into the water gas shift reactor, where the water gas shift reactor is under a temperature and pressure condition sufficient to generate the water gas shift reaction between some portion of the CO from the first gaseous stream and some portion of the generated steam to produce a third gaseous stream comprising a generated H contacting the third gaseous stream with a second hydroxide in the second absorption reactor to produce a second solid carbonate and a second water product, and producing a fourth gaseous stream comprising generated H transferring the first solid carbonate from the first absorption reactor to a regeneration reactor and generating a first decomposition reaction by, transferring the second solid carbonate from the second absorption reactor to the regeneration reactor and generating a second decomposition reaction by, discharging a rehydroxylation stream comprising some portion of the second water product from the second absorption reactor, and directing the rehydroxylation stream to a polishing reactor; and transferring the first remaining oxide and the second remaining oxide from the regeneration reactor to the polishing reactor and rehydroxylating the first remaining oxide and the second remaining oxide by,
