Charcoal adsorbents for glycerin purification

Abstract

Abstract The article is devoted to the research of the chemical composition of coals. The main goal of the research is to choose the method of its enrichment. The authors established that after the enrichment of coal, the ash content sharply decreased due to the washing off of its inorganic part. The process of coal enrichment, at a ratio of 1:2 (coal: water) has a positive effect on reducing the ash content by 1.3 times. Based on the data obtained, it was found out that the enrichment process in the coal production adsorbents is necessary to reduce their ash content. Based on the research a technological scheme for obtaining a carbon adsorbent and solutions for their regeneration were proposed.
