Investigation on the Differences of the Alcohols Conversion over H-SAPO-34 Zeolite

Chinese Journal of Magnetic Resonance, 2022
In this paper, the conversion of methanol and butanol and the differences in product distribution over H-SAPO-34 were investigated. Some important reaction intermediates were captured during the reaction process by using gas chromatography-mass ...

Crystallization Behavior of Isotactic Propene-Octene Random Copolymers [PDF]

, 2022
The crystallization behavior of random propene-octene isotactic copolymers (iPPC8) prepared with a homogeneous metallocene catalyst has been studied. Samples of iPPC8 with low octene content up to about 7 mol% were isothermally crystallized from the melt

Synthesis of TiO2 with Hierarchical Porosity for the Photooxidation of Propene

Molecules, 2017
The elimination of volatile organic compounds (VOCs) at low concentration is a subject of great interest because these compounds are very harmful for the environment and human health.

Engineering a Coordinatively Unsaturated Au–O–Ti3+ Structure Toward Unprecedented H2 Efficiency for Low-Temperature Propene Epoxidation with H2 and O2

Engineering, 2023
Since 1998, the Au–O–Ti4+ sites of Au/Ti-based catalysts have been widely accepted as the active sites for propene epoxidation with H2 and O2 at a relatively high temperature, although they are limited by poor H2 efficiency.

Synthesis of two new Nickel and CopperNickel vanadates used for propane oxidative dehydrogenation

Revista Facultad de Ingeniería Universidad de Antioquia, 2013
Two new vanadates have been successfully synthesized by the hydrothermal and coprecipitation methods. Both vanadates were calcined at 600 °C and the resulting catalysts were tested on reaction of oxidative dehydrogenation of propane.

Insight into the role of mesoporosity in the selective production of propene from methanol

Journal of Chemical Research, 2023
Microporous ZSM-5, hierarchical ZSM-5, and hierarchical ZSM-11 zeolites with different crystalline sizes were prepared to determine the relations of mesoporosity with catalytic performance in methanol-to-propene reaction.

FTIR Matrix-Isolation Study of the Reaction Products of Vanadium Atoms with Propene: Observation of Allylvanadium Hydride As a Precursor to Sacrificial Hydrogenation of Propene

, 2016
Vanadium atoms have been reacted with different partial pressures of propene in Ar under matrix-isolation conditions, and the products have been observed using Fourier transform infrared (FTIR) spectroscopy.
