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.","PeriodicalId":11462,"journal":{"name":"Ecology and Industry of Russia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48767373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
