Control of Contribution of Cracking and Intermolecular Hydrogen Transfer in Cracking of Gasoline Fractions in Fixed and Circulating Catalyst Bed Reactors

The studies were focused on the influence of key parameters (temperature, pressure, dilution of the reaction medium with an inert gas) of catalytic processes (cracking of vacuum gasoil, hydrogen-free upgrading and cracking of gasoline fractions) on the ratio of selectivities to cracking and intermolecular hydrogen transfer. Controlling the ratio of these reactions allows the required products to be obtained on the feedstock processing. Lengthening of the feedstock-catalyst contact time, a decrease in the proportion of the diluting inert gas, and the pressure rise provides an increase in the selectivity to hydrogen transfer. Fixed and circulating catalyst bed setups were used for the experiments. Transformations of the feedstock containing deuterated compounds were studied.

Cooperative effects of different temperatures and pressures on the initial and subsequent decomposition reactions of the nitrogen-rich energetic crystal 3,3′-dinitroamino-4,4′-azoxyfurazan

The initiation mechanisms of 3,3′-dinitroamino-4,4′-azoxyfurazan at different temperatures and pressures are bimolecular intermolecular hydrogen transfer and unimolecular N–NO2 bond breaking.
