System for on-demand hydrogen production from carrier fluid and disposal of solid by-products

Abstract

An apparatus for the controlled production of gas from first and second fluid reagents that produce gas and by-products when mixed is provided, the apparatus comprising: a reaction cylinder (10); inlets (12a, 12b) configured to supply the first and second reagents (HC, PS) to the reaction cylinder; a gas discharge circuit (18) connected to the reaction cylinder; a piston (14) inside the reaction cylinder that is actuated from the first end of the reaction cylinder and moves axially inside the cylinder to force any by-products against the second end of the cylinder and discharge any gas through the gas discharge circuit (18), wherein the gas discharge circuit is connected to the cylinder near the second end of the cylinder; and a closure device (22) at the second end of the cylinder that has a closed position that seals the second end of the cylinder and an open position that leaves the second end of the cylinder completely free so that any by-products within the cylinder can be extracted by the piston (14).
