1. Kinetic equations for the rate, and the time-rate-of-change of the rate, of the conversions of nitrogen-diluted isooctane on various cracking catalysts have been developed from data obtained in a gradient-free reactor. 2. The generality of the kin

A common type of rate equations for hydrocarbon conversions under reforming conditions has been shown, resulting from the features of the hydrocarbons and hydrogen adsorption on the Pt/Al2O3 catalyst. This has been confirmed by variations in the rate

A study was made of the influence of palladium and rhenium additives to alumina on the dispersity of the metal particles formed in catalysts prepared by depositing first an additive and then platinum. The dispersity of the particles formed was found

Under reforming conditions, the rate of n-heptane conversion on a large Pt/Al2O3 catalyst grain, in contrast to that in the kinetic region, depends on the hydrogen to hydrocarbon mole ratio. The rate equation for the reaction on a large grain agrees

General forms of the kinetic equations for the conversion of various hydrocarbons in reforming of multicomponent gasoline fractions on platinum/alumina catalysts have been confirmed experimentally by using a gradientless method.

X-ray diffraction studies of platinum-alumina catalysts in a high-temperature chamber indicate that in a stream of hydrogen starting from 550–600 K, platinum is practically completely reduced. In several cases at higher temperatures a platinum hydr

The rates of the total and individual directions of n-heptane conversion in reforming over platinum-on-alumina catalysts were shown to be independent of dilution with hydrogen. They can be described by simple equations following from kinetic concepts
