Condensation products (CP) formation during the aromatization of propane on pentasils modified by Zn and Ga (1–5%) has been studied by IR spectroscopy, and thermal and chemical analyses. The amount of CP increases with increasing Zn concentration b

The kinetics of transformations of propane and propylene on Ga-modified pentasils and the H-form of zeolite were investigated in a wide range of conversions (20–95%). The selectivity of formation of aromatic hydrocarbons (ArH) on Ga-pentasils is si

1. Pentasils containing 0.5–1% Zn are the most efficient catalysts of aromatization of lower alkanes; an increase in the amount of Zn in HTsVM to 5% activates methane formation to a significant degree. 2. Aromatization of propane on Zn-containing p

A need has been shown to evaluate certain quality characteristics of the pigments and dyes used in EPCC (dispersity and looseness) which affect the accuracy of metering them and dispersing them in a polymer medium.

1. Platinum- and zinc-containing catalysts based on pentasil HTsVM have been studied in the aromatization of C2-C3 alkanes. It is shown that modification of the H form of the zeolite by zinc oxide (0.5% Zn) doubles the yield of aromatic hydrocarbons

1. The Zn-pentasil system was studied by IR spectroscopy based on adsorption of pyridine. It was shown that zinc ions enter cation-exchange sites which are strong B sites. The Zn-HTsVM system is characterized in the general case by the presence of tw

1. The departure of aluminum from the lattice of pentasil (HTsVM) in conversions of ethylene and propane and during oxidative regenerations was established: a decrease in bridge OH groups (3610 cm−1) and the appearance of out-of-lattice A13+ ions (
