    Abstract: A gas generation system includes a reservoir for a reactant, a compressor configured to pressurize the reactant in the reservoir using an operating medium delivered into the reservoir, a gas generation component fed with the reactant using a reactant feed line, and a metering element disposed in the reactant feed line between the reservoir and the gas generation component. In addition, a method for operating a gas generation system includes controlling the delivery of compressed operating medium so as to maintain a pressure in the reservoir at a level corresponding to a pressure of the reactant downstream of the reservoir and metering the reactant in a feed line between the reservoir and the gas generation component.

    Abstract: Method of metering at least one solid, particulate catalyst into a reactor containing a fluidized bed (11) of particles in an at least partly gaseous medium, in which the catalyst is metered discontinuously at prescribed time intervals into the fluidized bed (11) at at least one metering point (10). According to the present invention, a fluid stream is firstly introduced into the reactor (5) so that a region having a reduced particle density is formed in the fluidized bed (11) around the metering point (10) and the catalyst is subsequently metered into this region. As a result of the prior introduction of a fluid stream (“preblowing”) before the actual introduction of the catalyst, the catalyst can penetrate significantly deeper into the fluidized bed from the metering point due to the reduced particle density and is dispersed better.

    Abstract: An apparatus is provided to generate a gas by mixing chemicals with water. Typically, the production of gas, particularly oxygen, by combining water with powders and other dry chemicals has not been widely employed. There have existed a number of preexisting barriers such as undesirable flow rates and yields. However, by utilizing multiple reaction chambers the flow rates and yields can be more precisely tailored for a variety of situations that may call for particular flow rates and yields. Additionally, the use of the dry chemicals would allow for a long self-life allowing the apparatus to be particularly useful in emergency situations.
