Clay- and zeolite-based biogeosorbents: modelling and properties

Abstract

This work presents data on the mineral and chemical composition of zeolite-containing and clay rocks considered as carriers for oil-oxidizing microorganisms, as well as their textural characteristics. The authors proved the use of mineral sorbents based on clay and zeolitecontaining rocks for design of a biogeosorption material of destructive type. The minerals met the requirements for oil sorbents (environmental compatibility, oil capacity, feasibility), and were biocompatible with Biotrin consortium. Hydrocarbon-oxidizing microorganisms combined with mineral sorbents had a significant destructive potential. The degradation of petroleum hydrocarbons by biogeosorbents modeled on 551, 541-31, 539-40 samples were 77, 60 and 65.5 % for 4 days, respectively.
