Natural zeolites are available in Indonesia very large quantities and the market at affordable prices. The use of zeolite has developed various fields industry, water treatment wastewater treatment. study on ability local natural to adsorb copper from acidic a laboratory Tangerang been conducted. XRD data show that consists mordenite as main mineral quartz an accessory mineral. Acid activation ...

Furfural is a platform molecule that can be catalytically converted using cascade series of reactions into levulinic esters, essential compounds used as fuel additives. Bifunctional catalysts containing Lewis and Brønsted acid sites such zeolites are commonly for these conversions. However, microporous often present diffusional restriction due to the size similarity furfural other molecules zeo...

This paper shows the results of a study focused on evolution and properties mortars made with mixture portland cement (PC) natural mordenite (Mor). To begin, samples mordenite, sand were studied X-ray diffraction (XRD), fluorescence (XRF) granulometric analysis (GA). Next, ratio 75% PC 25% prepared to determine their initial final setting times, consistency density. Continuing, density, weight ...
