In this present study, the catalytic dehydration of ethanol over three different Al-based solid acid catalysts including H-beta zeolite (HBZ), modified H-beta zeolite with ?-Al2O3 (Al-HBZ) and mixed ?-? phase of Al2O3 (M-Al) catalysts was investigated. Th... see more

Porang (Amorphophallus muelleri Blume) is an alternative food sources from forest. Porang grows under forest canopy and potentially developed to improve food security. Naturally harvested porang contains high oxalate and less glucomannan. This paper obser... see more

This work is devoted to the study of the catalytic properties of Al2O3 and SiO2 in the process of thermal conversion of ethanol, as well as to the determination of the acid characteristics of these oxides The catalytic properties of oxides in the thermal ... see more

The catalytic ethanol dehydration to diethyl ether (DEE) over the synthesized beta zeolite (BEA) with different acidity on catalysts having Na and mixed Na-H forms was studied. The Na form of BEA catalyst was synthesized via the hydrothermal process, incl... see more

Thermal crosslinking sequential method applied for DN-PVAs generation efficiently. The swelling measurements investigated that the hydrophilicity of the membrane decreases because of the collaboration of the second thermal crosslinked PVA matrix. The... see more

The catalysts ??/?-Al2O3 ? ??-La/?-Al2O3 were studied by methods of electron microscopy (EM) and temperature-programmed desorption (TPD) of ammonia. Their activity was studied in reaction of ethanol dehydration with formation of ethylene. Modification of ... see more

This research is motivated by the reduced reserves of fossil fuels in Indonesia, so that fossil fuel substitutes are needed, one of which is ethanol. It's just that to make ethanol as a fuel substitute for fossil fuels, a 99% concentration is required, wh... see more
