    摘要: Disclosed are a method and a corresponding apparatus for converting a biomass reactant into synthesis gas. The method includes the steps of (1) heating biomass in a first molten liquid bath at a first temperature, wherein the first temperature is at least about 100° C., but less than the decomposition temperature of the biomass, wherein gas comprising water is evaporated and air is pressed from the biomass, thereby yielding dried biomass with minimal air content. (2) Recapturing the moisture evaporated from the biomass in step 1 for use in the process gas. (3) Heating the dried biomass in a second molten liquid bath at a second temperature, wherein the second temperature is sufficiently high to cause flash pyrolysis of the dried biomass, thereby yielding product gases, tar, and char. (4) Inserting recaptured steam into the process gas, which may optionally include external natural gas or hydrogen gas or recycled syngas for mixing and reforming with tar and non-condensable gases. (5) Further reacting the product gases, tar, and char with the process gas within a third molten liquid bath at a third temperature which is equal to or greater than the second temperature within the second molten liquid bath, thereby yielding high quality and relatively clean synthesis gas after a relatively long residence time needed for char gasification. A portion of the synthesis gas so formed is combusted to heat the first, second, and third molten liquid baths, unless external natural or hydrogen gas is available for this use.

    摘要: A process for the removal of a high percentage of NOx and SOx from the gaseous effluent of a metal pickling operation comprising passing the effluent through an aqueous scrubber, treating the gaseous effluent from the scrubber with ozone, passing the effluent from the ozone treatment through a second aqueous scrubber thereby removing at least 80 vol % of the NOx and SOx present in the original effluent. The scrubbing solutions in both of the scrubbers preferably have a pH of from 7 to 14, more preferably 10 to 14. The scrubbing solutions in both scrubbers are caustic solutions containing sodium hydroxide or calcium hydroxide. The NOx and SOx in the scrubbers are converted into nitrate salts and sulfate salts, which are removed from the scrubbers.

    摘要: A thermal energy storage system is proposed in which the latent heat of fusion of common salts is used to store energy within a selectable temperature range, extending both above and below the melting/freezing temperature zone of the salt mixture. The salt mixture occupies interstitial void spaces in a solid endostructure. The solid material remains in the solid state throughout the thermal cycling of the energy storage system, and preferably has properties of thermal conduction and specific heat that enhance the behavior of the salt mixture alone, while being chemically compatible with all materials in the storage system. The storage system is capable of accepting and delivering heat at high rates, thereby allowing power generation using a suitable energy transfer media to power a turbine of an electric generator or a process heat need to provide a relatively local, dispatchable, rechargeable thermal storage system, combined with a suitably sized generator.

    摘要: Nitric oxide is removed from a gas stream by contacting the gas stream with oxygen in the presence of a metal-cation exchanged zeolite, thereby oxidizing the nitric oxide to nitrogen dioxide, then contacting the resulting nitrogen dioxide-containing gas stream with ozone, thereby converting the nitrogen dioxide to nitric acid, nitric acid precursors or mixtures thereof, then contacting the gas stream with an aqueous liquid, thereby scrubbing the nitric acid, nitric acid precursors or mixtures thereof from the gas stream. Contact of the gas stream with oxygen in the presence of a zeolite is carried out at a temperature above the temperature at which significant adsorption of nitrogen dioxide occurs, and the aqueous liquid used as scrubbing agent preferably has a pH greater than 7.

    摘要: Nitrogen oxides are removed from a waste gas stream by contacting the waste gas stream with ammonia, thereby reducing the nitrogen oxides to nitrogen. Residual nitrogen oxides and unreacted ammonia in the waste gas stream leaving the nitrogen oxides reducing step are oxidized to nitrogen pentoxide or nitric acid by contacting this gas stream with ozone. Contact of the ozone and waste gas is preferably carried out in the presence of an aqueous solution at a pH above about 9 and at a temperature above about 75° C., and this step is preferably carried out in the presence of an ammonia-oxidizing catalyst.
