Variable Valency

The process of oxidation of hydrocarbon with oxygen proceeds with formation of the corresponding hydroperoxide as the primary product [1,2]. A catalyst is the most important factor that influences on the direction of flow of the oxidation reaction. Catalysts based on metals of variable valency, and their derivatives are the most active in reactions of oxidation of hydrocarbon [3].

The reactions of liquid-phase oxidation of aliphatic oxygen containing hydrocarbons, in particular, nonanol-4 and nonanon-4 in the presence of polyethylene-polyamine complexes (PEPA) with sorbated ions of metals with changeable valency (Co2+,Cu2+, Ni2+) were studied. It revealed that the oxidation of nonanole-4 and nonanone-4 in the presence of Cu2+ and Ni2+ ions in the analyzed system is less active while in the presence of Co2+ ions decarboxylation of acids it is practically absent and it leads mainly to formation of carbonic acids. It has been established that the character of oxidation reaction mostly depends on the properties of metals fixed on polymer matrix.

The liquid-phase oxidation of 4-ethylecyclohexene by oxygen in the presence of a catalytic system (NH4)6Mo7O24 CoBr2) was investigated. The influence of various factors (temperature, duration, quantity of catalyst, molar ratios of reagents) on the oxidation reaction rates (conversion of feedstock, selectivity of reaction on oxy products) is determined

A mathematical model for nitrification in an aerated fixed bed reactor has been developed. This model is based on material balances in the bulk liquid, gas phase and in the biofilm area. The fixed bed is divided into a number of cells according to the reduced remixing behaviour. A fixed bed cell consists of 4 compartments: the support, the gas phase, the bulk liquid phase and the stagnant volume containing the biofilm. In the stagnant volume the biological transmutation of the ammonia is located. The transport phenomena are modelled with mass transfer formulations so that the balances could be formulated as an initial value problem. The results of the simulation and experiments are compared.
