摘要:
Provided is a method of encapsulating a metal in a zeolite. The method comprises inserting a metal precursor into a parent zeolite, and then converting the parent zeolite to a zeolite having a higher framework density than the parent zeolite. The conversion is achieved without the need of an organic structure directing agent.
摘要:
A mycotoxin adsorbent highly specific for A and B trichothecenes, and especially for vomitoxin (or deoxinivalenol) and T-2 toxin; as well as a process for the preparation of said mycotoxin adsorbent. The adsorbent is obtained by modifying the surface of an aluminum silicate using an organic functionalized-chain compound which provides it with high polarity properties. The use of this type of adsorbent in the preparation of balanced animal feed that avoid the toxic effects of the trichothecenes present in the feed and the use of the combination of this adsorbent with aluminum silicates or organic aluminum silicates for the preparation of balanced animal feeds that avoid the toxic effects of mycotoxins.

Colloidal crystalline molecular sieve seeds are used in phosphorus-containing crystalline molecular sieve manufacture. Certain of the products have enhanced utility in oxygenate conversions.
摘要:
Process for manufacturing an alkali metal aluminosilicate of zeolite wherein zeolite P seeds are produced in situ in a first reacting gel with a SiO2/Al2O3 ratio of above 2.2 and it is only after the formation of zeolite P seeds, but before said seeds have the time to fully grow, that sodium aluminate solution is added in order to get a gel which can have a SiO2/Al2O3 ratio of about 2 which therefore enables producing a zeolite P having also a SiO2/Al2O3 ratio of about 2.

摘要:
This application consists of a method for the synthesis of a type of FER/MOR composite molecular sieve. That method consisting of mixing FER seed crystals, MOR seed crystals, a silicon source, water and an acid or alkali, thus yielding a reaction mixture; by adjusting the proportions of the seed crystals added, the silicon-aluminium proportion, acidity/alkalinity and other reaction conditions, it is possible to obtain a dual phase composite molecular sieve within which the proportions of the crystal phases may be adjusted. In the synthesis process to which the method of this application relates, there is no need to add any organic template, thus reducing the cost of the reaction, in addition to reducing likely environmental pollution, thus having major potential applications.
摘要:
Provided is a chemical filter for silanol compound removal which is capable of efficiently removing a silanol compound in air. The chemical filter for silanol compound removal of the present invention uses an inorganic silica-based porous material such that a pH of a mixed solution obtained by mixing with pure water (content: 5 wt%) is 7 or less as an adsorbent.
