Serdukov O. Intensification of heat and mass transfer processes and improving equipment for the thermal decomposition of hydrocarbons magnesium

Object - teplomasoobmennye processes underlying the firing technology of carbonaceous raw materials and processes for preparation of magnesium oxide products of multi-purpose. Item - technological units - kiln hydrocarbons magnesium, raw materials, products, processes, and magnesium gidrodispersii, which are used as cover. Methods - problem solved with the use of the theoretical foundations percolation topochemical reactions and methods of differential thermal and X-ray structural analysis, IC, NMR, EPR spectroscopy, and microscopic measurements. Theoretical and practical results - to determine the kinetic regularities of thermal decomposition of magnesium bicarbonate granules in a rotary kiln shelf and mechanical function of temperature, grain size and homogeneity, the possibility of intensification of burning hydrocarbons magnesium and decrease of temperature due to the introduction of raw material of one of the catalysts and its mechanical and chemical activation process before the granulation, the results of the study offered as recommendations for implementation at the upper Issetskom and Lipetsk metallurgical plant (Russia), as well as project development at the NIOCHIM for organization of production of periclase-based raw materials in Ukraine. Novelty - mathematical models of the thermal conversion of magnesium granules hydrocarbons, which react in the atmosphere of a multicomponent gas mixture, take into account the sorption of gas phase diffusion of the initial and final products, the nucleation and movement of reaction interface; determine the mechanism and kinetics of magnesia gidrodispersy that contain film gels. The degree of implementation - pilot-scale tests. Region - chemical engineering.
