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

101 The paper describes the world's status of new processes of cumene synthesis on zeolite in liquid phase,[www.Sentencedict.com] demonstrates the performances of various catalysts for new processes.

102 NMP zeolite has a small head loss through a long time to deal with large amount of water and good renewable.

103 Application of zeolite catalyst in cumene process makes it possible to achieve better quality without pollution.

104 HZSM-5 zeolite catalyst was treated with aqueous H_3BO_3 and the catalytic activity of the prepared catalysts was investigated by the alkylation of toluene with ethanol.

105 The relationship between coking and deactivation of ZSM-5 type zeolite catalyst has been reviewed systematically.

106 Then, HCl solution was used as a regenerant for modified zeolite. Influence that concentration of HCl, flow rate and regenerating time on regeneration effect was also studied.

107 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.

110 The difference of gasoline and diesel yields between the composite and mechanical mixture was elucidated from the structure of composite zeolite and shape-selective catalysis of ZSM-5.

111 ZSM-5 zeolite membranes were prepared by second growth method and modified with metallic ion.

112 The constraint index for shape selectivity of zeolite catalyst of ZSM type has been determined by means of gas chromatography in connection with a continuous flow micro-reactor under normal pressure.

113 Catalysts for converting polyalkylaromatics to monoalkylaromatics, particularly cumene and ethyl benzene are disclosed which comprise aY-85 or a modified LZ-210 zeolite.

117 The sea water desalting agent consists of silver-carrying acid zeolite, silver oxide and barium hydroxide.

118 In this method, the activation energy is reduced during deaminization and the deaminizating rate and the retention of zeolite crystallinity after deaminization are increased.

119 The in-situ formed byproduct water strongly adsorbs on the B-acid site of zeolite, and would inhibit the further adsorption and reaction of the aromatic reactants and alcohol reagents.

120 Several factors that influence shape-selective synthesis of 2,6-dialkylnaphthalene over zeolite such as alkylating reagents, solvents and selection of zeolites are reviewed.
