Abstract
Samples of cryogels based on aqueous solutions of polyvinyl alcohol were investigated. The molecular weights of the cryogel samples varied from 25⋅103 to 60⋅103. It has been found that the ultimate strength of dry briquettes increased from 1.2 to 3.7 MPa with an increase in the polymer molecular weight. The resulting briquettes can be used, for example, as a proper domestic or industrial fuel.
期刊介绍：
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
