Development of method for determination of the kinetics constants of coal char gasification in pore diffusion regimes

Remkunas I., Donskoy I., Kozlov A. Development of method for determination of the kinetics constants of coal char gasification in pore diffusion regimes // E3S Web of Conferences. Т.114. ID: 07007. 2019. DOI: 10.1051/e3sconf/201911407007 In this paper, we developed a method for determining the kinetic constants of partially diffusion-controlled heterogeneous reactions in a porous sample of powder. Studies have been conducted on the experimental data of thermogravimetric analysis of carbon conversion...

Ways to improve the efficiency of carbon dioxide utilization and gas hydrate storage at low temperatures

Misyura S.Y., Donskoy I.G. Ways to improve the efficiency of carbon dioxide utilization and gas hydrate storage at low temperatures // Journal of CO2 Utilization. Vol.34. 2019. P.313-324. DOI: 10.1016/j.jcou.2019.07.010 The dissociation of gas hydrate in the form of pressed granules of different diameters has been investigated. Kinetic equations to describe dissociation of gas hydrates at negative temperatures have been obtained for the first time. The activation energy for CO2 hydrate is higher...
