摘要： A zeolite having a high silica-to-alumina ratio is heated to about 400°C to remove physically adsorbed water, followed by heating to in excess of about 650°C, to form a superheated dehydroxylated zeolite. The zeolite is used to adsorb trace moisture from a feed gas. The zeolite can also be prepared having a low level of metallic impurities by contacting the zeolite with an acid gas. This zeolite is particularly useful for removing trace metal impurities from acid gases such as hydrogen chloride and hydrogen bromide.
摘要翻译：将具有高二氧化硅 - 氧化铝比的沸石加热至约400℃以除去物理吸附的水，然后加热至超过约650℃，形成过热的脱羟基化沸石。沸石用于从进料气体吸附痕量的水分。也可以通过使沸石与酸性气体接触来制备具有低水平金属杂质的沸石。该沸石特别可用于从酸性气体如氯化氢和溴化氢中除去痕量金属杂质。

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 °C to remove physically absorbed water from the zeolite, followed by heating the zeolite to a temperature in excess of 650 °C, to form a superheated zeolite. Heating to temperatures of 650 °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.
