Lactose hydrogenation is a complex chemical process characterized by formation of numerous side products. Therefore, the synthesis efficient catalysts for lactose and investigation kinetics this are important increasing lactitol yield. Synthesis nanocatalysts based on ruthenium-containing nanoparticles (NPs) formed in pores hypercrosslinked polystyrene (HPS) modified with amino groups their catalytic properties described current work. The Ru species were incorporated HPS using wet...

In this paper for the first time we present a systematic study of influence hydrophobicity Pd(II) compounds, (CH3CN)2PdCl2, (PhCN)2PdCl2, (Sty)(CH3CN)PdCl2, and (StyPdCl2)2, on nanoparticle (NP) formation in pores hydrophobic micro/mesoporous hypercrosslinked polystyrene (HPS). The morphology composition HPS–Pd nanocomposites were studied using transmission electron microscopy, X-ray fluorescence measurements, photoelectron spectroscopy, liquid nitrogen physisorption. size location Pd...

Here, we report on the development of novel Zn-, Zn-Cr-, and Zn-Cu-containing catalysts using magnetic silica (Fe3O4-SiO2) as support. Transmission electron microscopy, powder X-ray diffraction, photoelectron spectroscopy (XPS) showed that iron oxide nanoparticles are located in mesoporous pores magnetite (spinel) structure remains virtually unchanged despite incorporation Zn Cr. According to XPS data, Cr species intermixed within structure. In case catalysts, a separate Cu2O phase was also...

An approach for analysis of thermal gradients in a catalytic packed bed milli-reactor operated under radio frequency (RF) heating has been presented. A single-point temperature measurement would cause the misinterpretation activity an RF-heated reactor, because presence gradient. For reliable data interpretation, should be measured at three positions along reactor length. The profile can accurately estimated with exact analytical solution one-dimensional (1D) convection and conduction...

This paper reports on ruthenium nanoparticles formation and stabilization by hypercrosslinked poly-styrene the catalytic properties of nanocomposites obtained. Hypercrosslinked polystyrene with functional groups without them was used. The were characterized using low-temperature nitrogen physisorption, X-ray photoelectron spectroscopy transmission electron mi-croscopy. It is established that tertiary amine group support influences both ru-thenium nanoparticles, their in selective...
