Characterization and catalytical properties of HZSM5 zeolite modified by niobium.
(Soc Brasileira Quimica, 1997-01-01)
HZSM5 zeolite was modified by exchanging proton by niobium (V). Several samples were obtained with various degrees of exchange. Pore volumes and acidity were measured to characterize these exchanged zeolites, Catalytic ...

Improvement of methane activation using n-hexane as co-reactant over Zn/HZSM-11 zeolite
(Elsevier Science, 2004-08-09)
Significance of effective conversion of methane (C1) to more valuable compounds such as aromatics is studied using n-hexane (C6) as co-reactant. AH yield was as high as 30 mol% C using the following reaction conditions: ...

(Universidad Nacional de Colombia - Facultad de Ingeniería, 2005)
Se estudió la deshidratación catalItica de etanol a etileno en fase gaseosa sobre HMOR (Si/Al = 6.5), HZSM-5 (Si/Al = 29), Cu-HZSM-5 (Si/Al = 98) y Fe-HZSM-5 (Si/Al = 151); a presión atmosférica y en un intervalo de ...
Cinética da produção de butenos a partir de butanol empregando catalisadores ácidos
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2017-12-01)
to environmental requirements, new producing routes have been pursued and the butanol
dehydration reaction is one of the most promising. HZSM-5 zeolites and -alumina acid
catalysts were synthesized at different conditions ...
