A method for production of N 2 and CO 2 from a reactor exhaust stream, comprising: passing a reactor exhaust stream comprising at least 70 vol% N 2 and at least 10 vol% CO 2 into a swing adsorption reactor comprising an adsorbent material, which includes a mixture of an alkali metal carbonate and an alkaline earth metal oxide and/or a transition metal oxide, the reactor exhaust stream having a pressure between 10 bara (1.0 MPaa) to 30 bara (3.0 MPaa); adsorbing CO 2 on the adsorbent material at an adsorption temperature of at least 400°C; recovering an N 2 stream with a purity of at least 95 vol% from a forward end of the reactor, the recovered N 2 stream having a pressure that differs from the pressure of the reactor exhaust stream by 0.5 bar (50 kPa) or less; reducing the pressure in the swing adsorption reactor to a pressure from 1.0 bara (0.1 MPaa) to 3.0 bara (0.3 MPaa) by outputting a blow down stream from at least one end of the reactor; purging the swing adsorption reactor with a steam purge at a pressure from 1.0 bara (0.1 MPaa) to 3.0 bara (0.3 MPaa) to generate a CO 2 recovery stream, the CO 2 recovery stream comprising at least 90% of the CO 2 present in the reactor exhaust stream, the steam purge containing less than 1.0 mole of H 2 O per mole of CO 2 in the reactor exhaust stream; and optionally further comprising passing a second purge stream through the swing adsorption reactor to generate a second CO 2 recovery stream, the second purge stream having a different composition than the steam purge, wherein the passing, the adsorbing, the recovering, the reducing, and the purging comprise a pressure swing adsorption cycle, and wherein the reactor exhaust stream, the steam purge, and the second purge stream, if used, correspond to at least 95 vol% of all gas flows introduced into the swing adsorption reactor during the pressure swing adsorption cycle. passing a reactor exhaust stream comprising at least 70 vol% N 2 and at least 10 vol% CO 2 into a swing adsorption reactor comprising an adsorbent material, which includes a mixture of an alkali metal carbonate and an alkaline earth metal oxide and/or a transition metal oxide, the reactor exhaust stream having a pressure between 10 bara (1.0 MPaa) to 30 bara (3.0 MPaa); adsorbing CO 2 on the adsorbent material at an adsorption temperature of at least 400°C; recovering an N 2 stream with a purity of at least 95 vol% from a forward end of the reactor, the recovered N 2 stream having a pressure that differs from the pressure of the reactor exhaust stream by 0.5 bar (50 kPa) or less; reducing the pressure in the swing adsorption reactor to a pressure from 1.0 bara (0.1 MPaa) to 3.0 bara (0.3 MPaa) by outputting a blow down stream from at least one end of the reactor; purging the swing adsorption reactor with a steam purge at a pressure from 1.0 bara (0.1 MPaa) to 3.0 bara (0.3 MPaa) to generate a CO 2 recovery stream, the CO 2 recovery stream comprising at least 90% of the CO 2 present in the reactor exhaust stream, the steam purge containing less than 1.0 mole of H 2 O per mole of CO 2 in the reactor exhaust stream; and optionally further comprising passing a second purge stream through the swing adsorption reactor to generate a second CO 2 recovery stream, the second purge stream having a different composition than the steam purge, wherein the passing, the adsorbing, the recovering, the reducing, and the purging comprise a pressure swing adsorption cycle, and wherein the reactor exhaust stream, the steam purge, and the second purge stream, if used, correspond to at least 95 vol% of all gas flows introduced into the swing adsorption reactor during the pressure swing adsorption cycle.
