Study of properties of granulated composite sorbents from peat-mineral mixtures
- Tver State Technical University
Abstract
Currently, one of the main tasks of the peat industry is the development of new types of products from biogenic raw materials. Creation and practical use of peat sorbents is complicated by irreversible phenomena in their structure during the production of hydrophilic materials. For activation of sorption centers various kinds of additives (synthetic surfactants, natural materials) are introduced. It is revealed that the introduction of clay materials contributes to the increase of absorption properties of peat products. Their use increases both absorption rate and absorption capacity. Increasing the drying temperature has a negative effect on the sorption properties of peat-mineral granules.
