The work proposed a macrokinetic model of first-order CO2 sorption on a 10 mol.% NaNO3/MgO sorbent. Based on the analysis of experimental gravimetric data, the maximum sorption capacity of the sorbent 10 mol.% NaNO3/MgO was determined, which does not depend on the partial pressure of CO2 and at 320 °C is 159% (based on the initial mass of the sample), or 13.4 mmol CO2/ gsorb. The calculated value of the sorption constant kads at temperatures of 280-320 °C and a partial pressure of CO2 of 0.50-0.75 atm is 0.017 min-1 atm-1. Based on the obtained kinetics, a simulation of an adiabatic and isothermal CO2 adsorber was made within the framework of a technological scheme for producing hydrogen 10 kg/h from natural gas at an operating pressure of 12 atm. During the calculations, it was shown that for the effective functioning of the adsorber, intensive removal of the heat released during the sorption process is necessary. This allows CO2 sorption to be carried out for 30 minutes at a temperature of 300 °C and a volumetric flow rate GHSV = 1170 h-1, while the concentration of CO2 at the outlet in dry gas does not exceed 1.5 mol.%.

Boreskov Institute of Catalysis, Novosibirsk, RussiaThe review focuses on jet fuel from microalgae biomass. Modern standards that biojet fuel obtained from microalgae biomass must meet are presented. The main ways of producing jet fuel from microalgae are considered, namely the processes of “oil to fuel”, “gas to fuel” and “carbohydrates to fuel”, as well as the production of this fuel along with other valuable products as a result of complex bioprocessing of biomass. Data on the potential for using biofuels from microalgae biomass in mixtures with traditional petroleum fuels are presented. The prospects for using this alternative fuel in modern aviation are considered.

The review paper considers main regularities of the oxidative chlorination of some unsaturated hydrocarbons: propylene, acetylene, butadiene-1,3 and benzene. It was shown that the implementation of such processes in the gas phase requires the presence of heterogeneous catalysts based on copper or palladium in the system. Depending on the process conditions, the products of additive or substitutive chlorination are formed. Kinetic equations and probable conversion mechanisms were proposed for the oxidative chlorination of propylene, acetylene and benzene. Prospects of the practical implementation of the oxidative chlorination of some unsaturated hydrocarbons were considered.
