Abstract:
1. A gas generator comprising: a high pressure gas-generation system including a fluidized-bed reactor capable of generating a product gas stream at a non-ambient, elevated nominal pressure; a thermal swing absorber having a first configuration and a second configuration with regard to being connected with the product gas stream, in the first configuration the thermal swing absorber is connected with the high pressure gas-generation system to receive the product gas stream and remove a constituent gas therefrom, and in the second configuration the thermal swing absorber is disconnected from the high pressure gas-generation system with regard to receiving the product gas stream and releases the constituent gas at a pressure that is substantially equal to the elevated nominal pressure, the thermal swing absorber being connected to the high pressure gas-generation system as an input source when in the second configuration to provide the released constituent gas as an input into the high pressure gas-generation system; and a methanator arranged upstream from the thermal swing absorber when the thermal swing absorber is in the first configuration and downstream from the fluidized-bed reactor to receive the product gas stream therefrom, the methanator including a catalyst capable of converting carbon oxides in the product gas stream into methane.
