1 Carbon, zeolite, and resins have a limited life.

2 A small bag of zeolite was used for three days, every two weeks to keep ammonia in check.

3 These interfering substances are adsorbed on to zeolite, silicic acid, or magnesium silicate.

4 There are minerals absorbing uranium: zeolite, montmorillonite, carbonaceous matter.

5 Manufacturing zeolite from kaoline is the most economical method.

6 Preferably, the vinylpyridine polymer encapsulates the titanium zeolite.

7 Evolution of zeolite synthesis was reviewed.

8 The results have shown that steel slag and zeolite can remove effectively phosphate and ammonia nitrogen from hogpen waste water.

9 Condensation of phenol and chloral over HY zeolite catalysts was studied in detail.

10 Zeolite B-CF-2 was synthesized using granules of boron-containing silicate porous glass in the mixture vapor of methylamine and water at 473 K.

11 In the alternative,[www.Sentencedict.com] the ferrierite zeolite particles are incorporated into the cracking catalyst as an integral component of the catalyst.

12 An experimental synthesis of 4A zeolite is carried out by use of the coal series kaolin roasted in the aqueous solution.

13 In this paper the deactivation of Y-type zeolite catalyst has been studied in theoretical and experimental aspects.

14 Conclusion The adsorptive capacity of diatomite, clinoptilolite, silk zeolite, and coal fly ash to DBP degradation dominant bacteria was enhanced after being modified.

15 Catalytic thermal cracking performance of modified ZSM-5 zeolite is evaluated through pure hydrocarbon impulsive micro-reaction pilot unit.

16 The calcination of HZSM-5 zeolite treated by sulfur acid not only could improve its acid quantity, but also increased strong acid sites with structure of super acid.

17 Such overwintering vats should be as simple as possible: externally filtered zeolite somewhere in the system to cope with ammonia.

18 The chemical transformations that can then occur are quite remarkable, making zeolites some of the most unusual catalysts known.

19 The author has put forward a new type of invented time scale for extending this method to reversible complex networks, e. g. the reaction of xylene isomerization over HZSM-5 zeolite catalyst.

20 The development of new molecular sieves, engineering development in the manufacture of molecular sieves and combination of zeolite catalysis with separation technology are also discussed.

21 Through test and commercial test, the processing technology of ultrafine grinding of natural zeolite is investigated.

22 Home water softeners make use of the ion exchange properties of natural or synthetic zeolite minerals.

23 The process of in-situ crystallization is that the roasted microparticles in the liquid phase convert into sodium silicoaluminate gel first and then the gels convert into zeolite Y gradually.

24 This thesis describes an industrial experiment about the production of cumene on zeolite catalyst in phenol - acetone plant of Jilin Petro- Chemical Co. Ltd.

25 Differential heats of adsorption (DHA) of alkenes and alkanes having similar structures on USY zeolite were measured with a SET ARAM microcalorimeter.

26 The activated process of improving adsorption capacity of natural zeolite is studied in this paper.

27 The phenomenon of phosphorus releasing was observed at the incipience of the investigation especially in the unit of zeolite.

28 The results show that all soil treatments except for sole use of zeolite have improved soil conditions for the growth of Sedum alfredii Hance.

29 With an aiminresolving the problem smoking of polymers on burning, a complex smoke suppressor consisting of ammonium molybdate and molybdic oxide has been prepared, using zeolite as the carrier.

30 Especially by the TS-1 modified with trimethylchlorosilane, much higher catalytic activity was achieved than by parent TS-1 zeolite in the phase-boundary catalysis.
