Results of experimental and production testing of developed technologies for the production of acid-activated adsorbents of MCA for purification of paraffin and ceresins on their compositions

The article mainly examines the adsorbents used in the process. At the same time, based on the results obtained, the use of a wide range ofprocessing of mineral oils and paraffin at refineries using domestic adsorbents and adsorbents developed in the country is justified. Long-term studies of technologies for producing bentonite and palygorskite adsorbents by acid activation, washing and drying have shown that the resulting sorbents have relatively low activity. In addition, regardless of the type of acid used (hydrochloric, sulfuric, etc.), the duration of the activation of clays practically does not decrease, which negatively affects the cost of the obtained adsorbents.
