The influence of conditions of oil shale preliminary mechanical activation on yield and composition of the products at thermolysis in water medium

Abstract

The paper introduces the data on the yield and composition of products of thermal destruction of oil shale organic substances after their preliminary mechanical treatment. It was shown that shale preliminary mechanical treatment in tetraline and ethanol medium doubles pyro-bitumoid yield. Hydrogen predominates in gaseous products formed at shale mechanical treatment and thermolysis; resinous components predominate in liquid products. Hydrocarbons in bitumoids are mainly represented by n-paraffins with a number of hydrogen atoms 17-25. It was shown that preliminary mechanical activation of oil shale in decane and tetraline medium with further thermolysis in water environment provides the growth of yield of distillate fractions boiled out at 350 °С
