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 ...

The catalytic conversion of methane (C1) into higher hydrocarbons using n-pentane (n-C5) as co-reactant over Zn/H-ZSM-11 zeolite material was studied. The aromatics yield was very high, achieving values of over 40mol% at ...

The biocide cations Ag+ and Zn2+ were hosted in the cavities of an ordered aluminosiliceous framework.Starting from sodium A-type zeolite (NaA), LTA containing Ag+ (AgA), Zn2+ (ZnA) and Ag+/Zn (AgZnA) at different cation ...

The behavior of Zn-ZSM-11 and Zn-BETA zeolites during the decomposition of low-density polyethylene has been studied in a batch, fixed-bed quartz reactor during successive reaction cycles without catalyst regeneration. The ...

The incorporation of a synthetic zeolite containing biocide cations in epoxy formulations to prevent biofilm formation and the biodegradation processes derived from its presence was studied. Biocidal action of Ag/Zn-exchanged ...

Low density polyethylene was converted into hydrocarbons over Zn- and H-ZSM-11 zeolite catalysts in a fixed-bed reactor during 20 and 60 min reaction time, 0.5 and 2.0 polymer to catalyst mass ratio at 500 °C. The zeolites ...
