1. A method of regenerating a sorbent of gas in a capture process of said gas, wherein the capture process comprises recirculating the sorbent between a gas capturing system and regenerating reactor system, the method comprising the regenerating reactor system performing the steps of:
receiving a solid sorbent to be regenerated, wherein the sorbent is a sorbent of carbon dioxide gas;
generating heat by combusting a fuel with an oxidising agent in the presence of a catalyst;
regenerating the sorbent by using the generated heat to indirectly heat the sorbent so that the sorbent releases carbon dioxide gas;
outputting the regenerated sorbent; and
outputting the released carbon dioxide gas;
wherein the received sorbent comprises a metal carbonate and the regenerated sorbent comprises a metal oxide, and
wherein the regenerating reactor system comprises a moving bed reactor;
wherein the regenerating reactor system comprises:
a sorbent input that receives the sorbent; and
a sorbent output that outputs the regenerated sorbent;
wherein the moving bed reactor comprises a plurality of tubes that provide the generated heat to the moving bed reactor;
the tubes are arranged in a plurality of horizontally aligned staggered layers; and
the sorbent travels around the outside of the tubes as it moves from the sorbent input to the sorbent output.
