5A Molecular Sieves For Hydrogen Production about Desiccant and Zeolites

A desiccant is a substance which is mainly used in absorbing water. It is widely used in excluding humidity which usually degrades and damages the products that are sensitive to moisture.

A desiccant is a substance which contains the properties of hygroscopic nature. One of the vital characteristics of a desiccant is that it is a low surface vapour pressure. When the desiccant is dry and cool, its surface vapour pressure becomes low and it can attract moisture from air, especially when it is moist and pressure vapour is high. When the desiccant becomes hot and wet, its surface vapour pressure reaches its highest point and excludes water vapour to the surrounding of the air.

Zeolites are a volcanic kind of rock which are consisted of hydrated aluminosilicates of the alkali metals of the earth. Zeolites comprise of three dimensional frameworks of crystals of alumina, anions, or tetrahedrite silica which are strongly bonded from all the corners.

When the level of humidity in the air stream decreases below the saturation point of the zeolite, it starts to release moisture back into the air stream. Hence, it does not eliminate moisture completely. But it only retains or release the moisture, depending on the relative level of humidity of the air stream and the saturation point of the zeolite.

Molecular Sieve For Hydrogen Purification:

The role of "molecular sieve for hydrogen purification" is that it helps in producing hydrogen which does not occur till the end of stream-methane process of reformation. Before the molecular sieve is made in use, the feed stock which looks more or less like a natural gas, has to undergo a process of hydrodesulfurization, a reformation of stream process, a process of heat recovery and a CO conversion process. The afore mentioned process-especially will further breakdown the complex form of structure of molecular feed-stock, preparing it for the last stage for purification of hydrogen.

Hydrogen Purification With The Help of 5A Molecules:

5A molecules are specialized in the separation of straight and chained-like form of hydrocarbons from one another. 13X molecular sieve is proficient in the exclusion of any additional CO2 or NH3, if found anywhere.

Molecular Sieve for Naphtha Drying

Naphtha is a hydrocarbon distillate which is the remaining from the process of coal tar or refining petroleum. It is a multifaceted mixture of chemicals that is broken down and converted into other chemicals from catalytic reforming or steam cracking.

Molecular Sieves

Molecular sieves are defined as a material that comprises very minute pores that have a similar size and shape. Because of this property, the smaller molecules of another material can easily pass through, but the larger molecules are blocked just like a sieve. This uniformity in its structure makes this material a great desiccant. In fact, some common examples of this would be activated charcoal/carbon or silica gel. These materials are used as desiccants for gases and liquids adsorbents that have tremendous capacity of adsorption than activated alumina and silica gel desiccant. It is extremely effective at removing water from liquid and gases.

Molecular sieve for naphtha drying are desorbed and hydrocarbons are dehydrogenated and used as desorbing agents.

The present invention relates to the preparation of high octane motor fuel sand more particularly relates to an improved process for upgrading naphtha for use as a blending stock in the preparation of high octane gasoline.

Present octane levels require the use of large quantities of relatively high octane blending stocks such as catalytic naphtha, polymer gasoline, hydrogenate and the like and permit the inclusion of much lesser amounts of light virgin naphtha than were formerly used in gasoline blending. This trendy away from the use of light virgin naphtha as a blending stock has created surpluses of such naphtha at many refineries.

The process of the invention may be further said -by considering a typical application of the process in a commercial refinery processing

The product naphtha fraction obtained from the process has the following composition and octane values:
