Have been determined the technical characteristics and elemental composition of shells. The elemental composition of the shell was determined by a microanalytical method such as 5Е С2000 model CNH-analyzer. The pyrolysis of shells investigated by using a standard quartz retort (tube) at different heating temperatures and determined the yields of pyrolysis products such as hard residue, tar, pyrolytic water, and gas. As a result of these experiments have been determined that 30% hard residue, higher yield 13% of tar, can be obtained at heating temperature 500oC. Thermogravimetric analysis of shells carried out in TG/DTA7200, Hitachi, Japan model equipment. The shells’ ash chemical composition was first time determined by the X-ray diffractions powder, that it consists of significantly higher 40% these chemical elements including manganese, nickel, little zinc, sulfur, aluminum, phosphorus, iron, magnesium, and calcium. The solubility of purified pyrolysis tar of shells in hexane, benzene and dichloromethane were investigated by using silicagel column and the chemical composition of each fraction determined by using of GC/MS chromatography system. The FTIR spectra of shell and pyrolysis tar determined by using of a Nicolet 20-PC spectrometer. The porosity structure of activated pyrolysis hard residue determined by the SEM analysis.
