摘要： The present invention relates to a one-dimensional silicate material ZEO-2 with a novel structure and a three-dimensional silicate molecular sieve ZEO-3 obtained by roasting ZEO-2 and a synthesis method therefor and a use thereof. The X-ray powder diffraction characteristics and crystal structures of the two silicate materials are represented. The one-dimensional silicate ZEO-2 can be synthesized by a simple method. The molecular sieve ZEO-3 can be obtained by calcining the one-dimensional silicate ZEO-2 to cause topological condensation. ZEO-2 can be used as a silicon source or a precursor in the synthesis of a novel molecular sieve. The molecular sieve ZEO-3 has good thermal stability and can be used as an adsorbent or a catalyst.

摘要： An adsorbent having a microwave absorption property is provided. The adsorbent having an improved microwave absorption property, which has a core-shell structure including a silicon carbide bead disposed therein, and an adsorbing material disposed outside the silicon carbide bead, can be provided. Also, the adsorbent may further include a plurality of silicon carbide particles dispersed and disposed therein and having a diameter of 1 μm to 10 μm, and the adsorbing material may be ion-exchanged with a cation. Therefore, the adsorbent can be useful in improving desorption efficiency since the adsorbent may be rapidly heated by microwaves to reach the desorption temperature due to high reactivity to microwaves. Also, the adsorbent can be useful in maintaining full adsorption capacity without having an influence on adsorption quantity since the silicon carbide bead is disposed in the inner core of the adsorbent. Further, when the adsorbent is applied to conventional systems for removing organic compounds using microwaves or dehumidification systems, the adsorbent can be semi-permanently used, and may also have an effect of enhancing the energy efficiency by 30% or more, compared to adsorbents used in the conventional systems.

摘要： A gas-adsorbing material may increase gas barrier properties for a target gas by reducing a gas-adsorption rate while maintaining gas-adsorption performance. A vacuum insulation material may use the gas-adsorbing material. The gas-adsorbing material may include a gas-adsorbing composition including a copper ion exchanged ZSM-5-type zeolite having a silica to alumina ratio ranging from about 10 to 50 in a framework of zeolite. A ratio of dealuminization of the ZSM-5-type zeolite is at least about 15%, and the gas-adsorbing material is capable of adsorbing at least nitrogen. Furthermore, the gas-adsorbing material may include a calcinated body of a compressed article comprising a gas-adsorbing composition including a copper ion exchanged ZSM-5-type zeolite having a silica to alumina ratio ranging from about 10 to 50 in a framework of zeolite (where a ratio of dealuminization of the ZSM-5-type zeolite is at least about 15%) and a moisture-absorbing material.

摘要： In a feed clean-up process at least two adsorbents (2, 4) are installed in front of an oligomerization reactor (3). Olefin feed is sent over one adsorbent (2) and the nitrile poisons are adsorbed so that clean feed will enter the reactor (3). Before the adsorbent (2) will be saturated, the feed (1) is sent to the other, fresh adsorbent (4). At the same time oligomerization product from the reactor (3) is used to desorb nitriles from the spent adsorbent (2).

摘要： The invention relates to a process for removing and recovering mercury, an impurity, from a hydrocarbon feedstream containing oxygen, such as introduced during hydraulic fracturing. Mercury is selectively removed to very low levels of concentration from fluid streams such as natural gas, cracked gas, hydrogen or naphtha by passage of the stream through an adsorbent bed containing particles of a zeolitic molecular sieve preferably having pore diameters of at least 3.0 angstroms and in which the zeolite crystallites are formed into an aggregate (cylindrical or beads) which contain ionic or elemental silver. These adsorbent particles maintain their capacity for removal of mercury despite the presence of oxygen.
