Influence of Temperature on the Total Surface Area of Nanopores of Leningrad Deposits Oil Shale

Abstract:

The article is devoted to the analysis of the influence of heat treatment of oil shale of the Leningrad field on the total surface area of nanopores and total porosity. Oil shale with particle size up to 0.125 mm in the form of powder and in the form of shale briquette was subjected to heat treatment. The change in the total porosity was studied in the temperature range (0÷1000) oC. The change in the total surface area of nanopores was studied by comparing the initial sample of oil shale with the oil shale ash obtained at 1000 oC. The data presented in this paper is indicative of a decrease in the oil shale nanopores total surface area under heat treatment, for example, for pore diameters (3÷4) nm the area decreases from 15.29 cm²/g to 2.563 cm²/g.
