    摘要: The present invention provides a low pressure generating plasma reactor closed loop process, comprising: feeding a fresh feed gas flow and a fresh feed absorption liquid flow to a plasma reactor closed loop comprising a condenser, a liquid loop, a recycle gas loop, and a plasma generator; converting feed gas to reactive plasma products in the plasma generator; quenching and absorbing the reactive plasma products into an absorption liquid circulating in the liquid loop where the reactive plasma products react to form liquid reaction products, thereby generating low pressure in the closed loop; monitoring the composition and low pressure of the recycle gas loop and, if the pressure increases, adjusting the composition of the fresh feed gas flow and/or fresh feed absorption liquid flow to bring the composition of the feed gas towards stoichiometric ratio with the absorbed reactive plasma products; extracting circulating absorption liquid, containing the liquid reaction products, from the plasma reactor closed loop as a product flow. The present invention also provides a low pressure generating plasma reactor closed loop system, comprising a plasma generator, a condenser, a recycle gas loop, a liquid loop, and a pump.

    摘要: Devices for delivering a controlled concentration of an agent are provided. The device includes a reservoir for the agent and a flow control portion operably connected to the reservoir. The device also includes a valve for releasing the agent from the flow control portion and a pump for flowing air to mix with the agent released by the valve and for flowing the agent and air mixture out of the device. Methods of delivering a vaporized agent to a subject are also provided. The methods include storing a liquid agent in a reservoir of a device and flowing the agent into a flow control chamber to change the agent to a gas. The methods also include mixing the agent in gas form with air and flowing the agent and air mixture out of the device to be delivered to a subject.

    摘要: A catalyst for purification of exhaust gases including (1) a catalysis-promoting coating comprising a noble metal catalyst and a NOx storage component loaded onto a carrier material, wherein the NOx storage component comprises an alkali metal and, (2) a ceramic substrate for supporting the catalysis-promoting coating, wherein the ceramic substrate exhibits resistance to alkali metal migration below 1000 DEG C and a coefficient of thermal expansion of less than about 25x10 / DEG C (25-800 DEG C). A second aspect of the invention is a process for purifying an exhaust gas from a lean burn engine involving simultaneously removing carbon monoxide, hydrocarbons and nitrogen oxides by bringing the exhaust gas from a lean burn engine into contact with the exhaust gas purifying catalyst of the present invention disclosed above. In this process a majority of the nitrogen oxides in the exhaust gas are adsorbed to the NOx storage component on the porous support under a lean burn atmosphere in which oxidizing concentrations are above a stoichiometric point that is required for oxidizing components to be oxidized in the exhaust gas. Furthermore, when the exhaust gas is temporarily change from lean burn to fuel-rich, the adsorbed nitrogen oxides are released and chemically reduced by a reaction with the hydrocarbons and carbon monoxide in the exhaust gas under a stoichiometric atmosphere or a fuel-rich atmosphere in which oxygen concentrations are below stoichiometric point.
