摘要:
The invention relates to a cyclical method for producing a nitrogen fraction (2), the purity of which is greater than or equal to 95 mol %, and a hydrocarbon-enriched fraction (3) from a filler containing nitrogen and a hydrocarbon, said method using a specific class of porous hybrid solids as an adsorbent in a pressure-swing adsorption (PSA) process. The invention also relates to equipment for implementing said method.

Provided is a novel metal-organic framework having a 3D structure formed by including Zr 6 cluster secondary building units and multitopic linkers capable of forming double or quadruple bonds therewith; a manufacturing method thereof; and use thereof as an adsorbent and a catalyst.
摘要:
The present invention relates to the use of solids consisting of a metal-organic framework (MOF) and having the units of the following formula (I): MmOkXILp as a nitrogen-oxide catalyst. The present invention also relates to devices for enabling the implementation of said use. The nitrogen oxides in question are nitrogen monoxide and nitrogen dioxide, collectively referred to as NOx. The MOF solids of the present invention are advantageously capable of removing nitrogen oxides from a liquid or gaseous effluent, for example from water, from the exhaust gases of a vehicle, factory, workshop, laboratory, stored products, urban air vents, etc., without any reducing agent and at a low temperature. The DeNOx catalysis is a major issue for our societies. The invention can be used for reducing or even avoiding the consequences for public health of the toxic NOx gases resulting from human activity.

The present invention relates to an absorbent using the porous organic-inorganic hybrid material(s) containing iron having a large surface area and a high pore volume, in particular, a water absorbent. Also, it relates to an absorbent that can be used in humidifiers, dehumidifiers and coolers/heaters, which can easily absorb or desorb at 100°C and below, and has a great absorption amount per weight of the absorbent. Also, the present invention relates to a novel preparation method of porous organic-inorganic hybrid material(s), in particular, a preparation method characterized by not using hydrofluoric acid, porous organic-inorganic hybrid material(s) prepared by said preparation method, and a use as an absorbent thereof.
摘要:
The present invention relates to an adsorbent obtained by using porous hybrid inorganic-organic materials that have high surface area, and have pore with the size of molecules or nanometers. More specifically, the present invention relates to a water adsorbent showing facile adsorption-desorption even below 100 0C, having high adsorption capacity, and having high desorption capacity when it is heated up to the temperature below 100 °C. The adsorbent of the present invention can be applied to a humidifier, dehumidifier, cooler and heater. The present invention also relates to a technology to control humidity using the adsorbent.
