摘要:
Disclosed herein is a clay-alkali-amine CO2 sorbent composition prepared by integrating a clay substrate, basic alkali salt, and amine liquid. The basic alkali salt is present relative to the clay substrate in a weight ratio of from about 1 part to about 50 parts per 100 parts of the clay substrate. The amine liquid is present relative to a clay-alkali combination in a weight ratio of from about 1 part to about 10 parts per 10 parts of the clay-alkali combination. The clay-alkali-amine C02 sorbent is particularly advantageous for low temperature CO2 removal cycles in a gas stream having a C02 concentration less than around 2000 ppm and an oxygen concentration around 21%, such as air.

摘要:
The present invention relates to the use of palladium doped ZSM-5 to adsorb volatile organic compounds (VOCs) derived from organic matter, wherein the Si:Al ratio of the ZSM-5 is less than 5 or equal to 100:1, and wherein the palladium doped ZSM-5 is used in an environment comprising less than 10 vol % of oxygen.
摘要:
The invention relates to a system of encapsulating a hygroscopic salt tablet of the type used to absorb moisture in closed environments. Said encapsulation consists of seamless cloth, usually “non-woven”, arranged so that it includes folds that minimize the air chamber between the tablet and the covering thereof. Said arrangement allows the tablet to work more effectively than other similar ones by eliminating the resistance that the air causes to the absorption of moisture. Said tablet begins to work when the ambient moisture is greater than 55%-60% and is used inside a plastic device that has slots to absorb the moist air and has a bottom container for deposit of a brine resulting from the process of absorbing moisture.
