Abstract

The technical and technological processing features of fine-grained carbonaceous technological waste into environmentally friendly products with significant energy and resource saving were introduced. The article defines products which are the recycled highly efficient and competitive spherical activated carbons produced by high-speed pelletisation in aqueous medium with various hydrocarbon binders. The article describes the step-by-step manufacturing of spherical pellets by high-speed components mixing in aqueous medium. The main production parameters of spherical activated carbons (SAC) from the introduced raw materials, the formulation (ratio of components), the conditions for pelletisation and subsequent high-temperature carbonization and activation were identified. The parameters of the porous structure, sorption properties and technical features of the obtained materials were assessed according to the methods typical for the validation of activated carbons. It was confirmed that the characteristics of developed SAC were not inferior to industrial activated carbons in terms of porous structure and sorption properties, and significantly exceed them in terms of percentage of ash and endurance capability.

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
