Influence of mechanodegradation on the value of the Toms effect

Article preview

In the process of preparation of polymer solutions, depending on the type of stirring device and the shape of the vessel, power on the shaft and mixing time, polymer molecules are subjected to mechanical impact and in accordance with the level of this impact can be partially or completely destroyed (mechanodestructured).

Application of the fountain bed method to some technological processes

Article preview

Recent decades have been marked by the emergence of fundamentally new technological techniques designed to intensify various technological processes. Among such techniques is the method of weighted layer. Production of non-ferrous metals (pyrometallurgical processing), oil refining, obtaining some building materials, sulfuric acid production, drying of grain, plastic masses and paste-like materials, granulation of salts and some other processes are developed to a greater or lesser extent on the basis of application of the suspended bed.

On the kinetics of ion exchange adsorption in a gushing ionite layer

Article preview

Ion exchange is widely used in hydrometallurgy, especially in the extraction of rare earth or dispersed elements from solutions. The field of application of ionites in non-ferrous metallurgy can be significantly expanded, firstly, if sufficiently cheap and high-capacity domestic ionites are available, and secondly, if the mechanism of the ion exchange process is known, which makes it possible to obtain, analyze and use appropriate kinetic equations. For a number of cations (copper, zinc, etc.), the domestic KU-2 cationite can be confidently attributed to the number of ionites meeting the first requirement. Not having selectivity with respect to ions of a certain grade in the combined presence of several ions, KU-2 cationite turns out to be quite capacious with respect to each of the cations individually.

О фонтанирующем слое в системе жидкость-твердое

Article preview

Одним из интенсивных способов осуществления контакти­рования твердого материала с жидкостью может служить фон­танирующий слой. Если его гидродинамическим законо­мерностям в системе Г—Т посвящено значительное число работ, то по гидродинамике и масеообмену фонтанирующего слоя в системе Ж—Т — работ практически нет. Отсутствие полной аналогии в пове­дении этих двух гетерогенных систем, вы­званной существенным различием в вяз­кости и плотности легких фаз Ж и Г, на­стоятельно требует проведения самостоя­тельных гидродинамических исследований фонтанирующего слоя в системе Ж—Т ...

О процессе обжига пирротина

Article preview

Большой экспериментальный материал по кинетике про­цесса обжига пирротина  позволил установить влияние температуры, концентрации кислорода, размеров частиц на скорость процесса окисления. Окислительный обжиг пирротинов представляет собой сложный физико-химический гетеро­генный процесс, сопровождаемый образованием газообразных и твердых продуктов реакции, что приводит к появлению допол­нительного сопротивления массопередаче, вызванному диффу­зией кислорода через пористый слей твердых окислов ...
