abstract: |
The "green" acidic clinoptilolite (HCLIN) samples were prepared by decomposition of
an ammonium exchanged natural zeolite NH4CLIN at different temperatures. And their
crystalline, morphology, porosity, acidity were investigated. The dehydroxylation
due to thermal treatment causes fading away of the weak Brønsted acid sites (BS).
Samples' activity in etherification of glycerol and tert-butanol will be decreased
if it were calcined at a higher temperature or in a long time at 300°C. Besides, the
glycerol conversion and the selectivity of di-ether as a renewable fuel additive were
enhanced.

Die "grünen" sauren Klinoptilolith (HCLIN)-Proben wurden durch Zersetzung eines mit
Ammonium ausgetauschten natürlichen Zeoliths NH4CLIN bei verschiedenen Temperaturen
hergestellt. Und ihre Kristallinität, Morphologie, Porosität und Säure wurden untersucht.
Die Dehydroxylierung aufgrund der thermischen Behandlung führt zum Verblassen der
schwachen Brønsted-Säure-Zentren (BS), die bei 300 °C erhalten wurden, und dann wird
die Veretherung von Glycerin und tert-Butanol verringert. Außerdem wurden der Glycerinumsatz
und die Selektivität von Diether als erneuerbarer Kraftstoffzusatz untersucht.
