    • A method for generating a hydride gas of metal M1 in an electrochemical cell comprising a cathode comprising metal M1, a sacrificial anode comprising metal M2, an initial concentration of aqueous electrolyte solution comprising a metal hydroxide, M3OH, wherein the sacrificial metal anode electrochemically oxidizes in the presence of the aqueous electrolyte solution comprising M3OH to form a metal salt, and the hydride gas of metal M1 is formed by reducing the metal M1 of the cathode. The method comprises the steps of determining solubility profile curves of the metal salt as the M3OH is consumed and the metal oxide is formed by the oxidation reaction at various concentrations of M3OH; determining a maximum concentration of M3OH that, as it is consumed, does not yield a concentration of metal salt that precipitates out of the electrolyte solution; and choosing a concentration of M3OH that is in the range of at and within 5% less than the maximum concentration of M3OH to be the initial concentration of M3OH.

    • Adsorption process for recovering ozone from a feed gas mixture containing at least ozone and oxygen comprising (a) introducing the feed gas mixture into a first end of an adsorber vessel containing a zeolite adsorbent and selectively adsorbing ozone on the adsorbent; (b) withdrawing from a second end of the vessel a stream of oxygen essentially free of ozone; (c) terminating the flow of the feed gas mixture, introducing a purge gas into the second end of the vessel, and withdrawing from the first end of the vessel an outlet gas mixture containing at least purge gas and desorbed ozone; and (d) introducing an additional component into the feed gas mixture and/or the purge gas and adsorbing the additional component on the zeolite adsorbent. The additional component when adsorbed reduces the decomposition of ozone that would occur in the absence of the additional component adsorbed on the zeolite adsorbent.

    • Apparatus and method to improve flow of fluid through an annular bed in a radial flow treatment vessel. An elongated annular baffle is disposed in the reactor adjacent the bed to impart generally U-shaped flow to the fluid either prior to entering or after it exits the bed thus achieving an overall serpentine or reverse U-shaped flow pattern as the fluid proceeds from an entry port to an exit port in the reactor. Means are provided in the baffle to permit minor amounts of fluid to bypass the generally U-shaped flow path in order to correct fluid flow maldistribution through the bed that is attributed to frictional pressure drop in the flow channels adjacent to the bed. A vessel according to the invention can be operated with fluid flow through the vessel in either direction.

    • A method of forming a low gloss, high solids polyurea coating containing very low volatile organic compounds (VOC) in the coating composition. The low volatile content not only makes the coating environmentally friendly but allows it to be applied at variable thickness levels and over a wide variety of environmental conditions. The coating composition is comprised of an isocyanate reactive agent containing a secondary diamine, a polyisocyanate, a gloss reducing agent and a viscosity modifier. The gloss reducing agent is generally pre-mixed into an isocyanate reactive agent containing a secondary diamine and/or polyisocyanate containing the viscosity modifier before mixing the two components together to form a low gloss polyurea coating.
