zeolite

It was found that the citric acid treatment of β zeolite had the function of both dealuminization and realuminization;

Grayish white powder or pellets and important inorganic salt products,4A zeolite is crystal lagoriolite.

The best choice for separating diethylbenzene is the adsorptive separation by zeolite adsorbents in high efficiency.

The performance of ZSM5、TRA and ZSM5-TRA zeolite catalysts(TRA is one kind of the ZSM series zeolites) for the vapour-phase transalkylation of poly-alkylbenzene have been studied.

FZT (the zeolite carrying copper) as an algaecide to kill and control the red tide organisms was stadied.

Taking acid-treated stellerite as main material, zeolite X powder was prepared by hydrothermal method.

Hydration of α pinene catalyzed by dealuminated ultrastable Y zeolite molecular sieve(DUSY)was studied.

A series of ultrastable Y zeolites with varies Si/Al mol ratio prepared by different dealumination methods have been investigated.

MOR zeolite was dispersed into poly(ethylene glycol)oligomer to form a stable gel. Its Electrochemical behavior was first detected by a cyclic voltammeter.

The effects of the catalyst dosage and the preparation conditions of HZ-1 zeolite,for example, number of exchange times on the benzoylation of toluene were studied.

Heulandite is one of the most common and one of the most well known members of the Zeolite Group. It can have a nice pearly luster and lovely colored hues......

The profiling/flooding efficiency and the injection technology of zeolite profile modificator(ZPM) in polymer flood are investigated on artificial cores,which contain 3 layers 0.

1.Blast furnace slags were partially replaced by artificial and natural pozzolanic materials, such as pozzolan , fly ash and zeolite,to produce alkali activated slag cement(AASC).

R esults show that the modified cement with good durability, small expansion and low alkality can be made by use of gypsum and zeolite modifying alumina cement.

The selective Production of monomethylamine (MMA) from methanol and ammonia was studied over some adhesive zeolites at temperature of 425℃ under ambient pressures.
