CATALYSIS BY METAL-CONTAINING ZEOLITES .1. BASIC SITES
(Soc Brasileira QuimicaSao PauloBrasil, 1995)
Improvements in the synthesis of zeolites with low Si/Al ratio from Venezuelan sodium silicate for an environmentally friendly process
(Ingeniería e Investigación, 2017)
Study of the alkylation of phenol with methanol on Zn(H)-exchanged NaY zeolites
(Springer, 2011-07)
The gas-phase alkylation of phenol with methanol was studied at 473 K on zeolite NaY exchanged with Zn+2 (samples Zn(x)NaY) or H+ (samples Na(x)HY) cations. Zeolite NaY contained only weak and medium Lewis acid sites. The ...
Zeolites surface reactions pointed out by charge parameters
(Elsevier Science, 2001-08)
The diffusion potential technique was applied to determine the isoelectric point (IEP) of solid samples taken after different reaction times in two selected zeolite hydrothermal transformations (1). NaA to HS and (2) NaY ...
STUDY OF THE ZEOLITIZATION PROCESS OF FLY ASH USING AN ORTHOGONAL ARRAY OF TAGUCHI EXPERIMENTAL DESIGN
(Sociedad Chilena de Química, 2009)
Exhausted fluid catalytic cracking catalysts as raw materials for zeolite synthesis
(Elsevier Science, 2006-07)
The utilization of exhausted fluid catalytic cracking (FCC) catalysts as raw materials for the zeolite synthesis was analyzed. Samples of the catalysts directly released from FCC units and the corresponding impact grinding ...
Magnetic Proton Relaxation of Ammonia Adsorbed on Na-X Zeolite
(Zeitschrift für Physikalische Chemie Neue Folge, 2017)
Ceramic papers containing Y zeolite for toluene removal
(Elsevier Science, 2011-11)
A papermaking technique with a dual polyelectrolyte retention system was used for the preparation of NaY zeolite-containing papers, which implied the use of cationic and anionic polymers. Two kinds of fibers were employed, ...
