Mild Dealumination of H-ZSM-5 Zeolite for Enhanced Conversion of Glucose into 5-Hydroxymethylfurfural in a Biphasic Solvent System
TL;DR: In this paper , a commercial H-ZSM-5 zeolite was used as a starting material for preparing a series of acid catalysts with bifunctionality for direct dehydration of glucose to HMF in a biphasic water/tetrahydrofuran system.
Journal ArticleDOI

TL;DR: In this paper , the byproduct of the previous transesterification, glycerol was utilised as an acid catalyst precursor for biodiesel production, and the synthesised acidic glycerols catalysts were characterised by various analytical techniques such as thermalgravimetric analyser (TGA), infrared spectroscopy, surface properties adsorption-desorption by nitrogen gas, ammonia-temperature programmed desorption (NH3-TPD), X-ray diffraction spectraopy (XRD), elemental composition analysis by energy dispersive spectrometer (EDX) and surface micrographic morphologies by field emission electron microscope (FESEM).
Journal ArticleDOI
Modified Sulfonated Glucose-Catalyzed Esterification of Palm Fatty Acid Distillate: Kinetics and Fuel Properties
TL;DR: In this paper, a modified sulfonated carbonized glucose (SCG) catalyst was used for the esterification of PFAD to biodiesel in a three necked conventional reflux batch reactor.
Journal ArticleDOI
Bifunctional acid–base strontium–titanium mixed oxides supported on SBA-15 for selective synthesis of renewable branched bio-jet fuel precursor
TL;DR: Aldol condensation with 2-butanone using strontium (Sr) and titanium (Ti) mixed oxides (STO) loaded onto mesoporous silica SBA-15 (SBA15) was carried out batchwise under a pressurized nitrogen atmosphere as mentioned in this paper .
Journal ArticleDOI
