Abstract

Development of high-effective oil sorbents on the basis of microencapsulation/ microgranulation techniques M. S. Vilessova, L. A. Rubinchik, N. N. Saprykina, R. P. Stankevich & B. I. Tkachev Russian Scientific Center "Applied Chemistry", Russia Delivery Systems International Ltd., Russia Abstract The work was devoted to developing oil sorbents of novel type capable of forming a semisolid layer when taking up the spilled hydrocarbon in order that the resulting stuff could easily be picked up with mechanical devices and could firmly retain absorbed petroleum products. The work comprises three principal stages: - choice and modification of dispersed solid carrier; - study and choice of polymer ingredients; - development of some appropriate microencapsulation (microgranulation) technology. Expanded perlite (further perlite) and porographite have been selected for using as solid substrates for their further treating with polymers. The general approaches to the design o
