    摘要： A method for removing trace moisture from a gas is disclosed. The method involves heating a zeolite having a high silica-to-alumina ratio to about 400.degree. C. to remove physically absorbed water from the zeolite, followed by heating the zeolite to a temperature in excess of 650.degree. C., to form a superheated zeolite. Heating to temperatures of 650.degree. C. or above is believed to cause dehydroxylation of the zeolite. A method for the preparation of a dehydroxylated zeolite is also disclosed. The superheated zeolite is contacted with the gas, thereby adsorbing water from the gas. A dehydroxylated zeolite for removing trace moisture from a gas wherein the zeolite has a high silica-to-alumina ratio and a low level of metallic impurities is also disclosed. The zeolite and methods of the invention are particularly useful for removing trace water from acid gases such as hydrogen chloride and hydrogen bromide.

    摘要： An apparatus and method for generating moisture standards in gases are disclosed. In particular, the invention relates to an apparatus for introducing a preselected amount of water vapor or other vaporized liquid into a flowing gas stream at a constant rate, which comprises a suitable syringe having a needle attached thereto; an evaporator attached to said needle, wherein the evaporator is located in the flowing gas stream; and a means for applying pressure to the syringe, such that water or other liquid may be delivered at a constant rate from the syringe through the needle into the evaporator. The invention also relates to a method for introducing a preselected amount of water vapor or other vaporized liquid into a flowing gas stream at a constant rate, which comprises providing a syringe having a needle attached thereto, wherein the syringe contains the water or other liquid to be vaporized; applying pressure to the syringe, such that water or other liquid is transferred at a constant rate from the syringe through the needle into an evaporator, said evaporator being attached to one end of the needle, and situated in the flowing gas stream; and allowing the water or other liquid to evaporate from the evaporator into the flowing gas stream. The apparatus and method of the invention are useful for the generation of low levels of moisture, and are especially useful where quick and reliable changes of moisture level in the gas is desired. Thus, the apparatus and method are useful in the generation of primary moisture standards for use in the calibration of moisture analyzing instruments, such as FTIR spectrometers.

    摘要： A process for removing trace amounts of moisture and/or one or more impurities from contaminated hydride, inert and non-reactive gases, thus decreasing the concentration of the impurities to parts-per-billion (ppb) or parts-per-trillion (ppt) levels. The gas purifier materials of this invention include thermally activated aluminas, said aluminas including organic alumina materials, modified organic alumina materials, and modified inorganic aluminas. The thermally activated alumina materials of this invention are activated by heating the alumina material at a temperature between about 50° C.–1000° C. in an inert or non-inert atmosphere or in a vacuum and maintaining the activated material in the inert or non-inert atmosphere or in a vacuum atmosphere subsequent to said activation but prior to use.

    摘要： Gas purifier system containing a preconditioned ultra-low emission (P-ULE) carbon for reducing trace impurities such as organic compounds and carbon monoxide in reactive fluids such as ammonia, hydrogen chloride, hydrogen bromide, and chlorine to sub-ppb levels. P-ULE is capable of removing impurities from a reactive fluid down to parts-per-billion (ppb) and sub-ppb levels without concurrently emitting other impurities such as moisture or carbon dioxide into the purified reactive fluid. The P-ULE carbon is prepared by heating a carbon material to temperatures between about 300° C. to 800° C. in an ultra-dry, inert gas stream, to produce an ultra-low emission (ULE) carbon material, subjecting the ULE carbon to a second activation process under a reactive gas atmosphere to produce a P-ULE carbon and storing the P-ULE carbon in an environment that minimizes contamination of the P-ULE prior to its use in a gas purifier system.

    摘要： Trace impurities such as organic compounds and carbon monoxide are reduced to sub-ppb levels in gases such as nitrogen, helium and argon, by gas purifying systems that contain an ultra-low emission (ULE) carbon material. Ultra-low emission (ULE) carbon materials can be made from commercially available carbon materials in the form of pellets, extrudates and beads and is capable of removing impurities from a gas stream down to parts-per-billion (ppb) and sub-ppb levels without concurrently emitting other impurities such as moisture or carbon dioxide to the purified gas stream. The carbon material is superactivated by heating the carbon to temperatures from 300° to about 800° degrees C. in an ultra-dry, inert gas stream. The ultra-low emission (ULE) carbon material is handled and stored in an environment that minimizes contamination from moisture and other oxygenated species in order to maintain its ppb and sub-ppb impurity removal and low emission properties. The ultra-low emission (ULE) carbon material can be used as “stand-alone” purifier material or in combination with other scavenging materials that are capable of removing large quantities of impurities such as oxygen and moisture that are not removed or only marginally removed by the ultra-low emission (ULE) carbon material.
