Abstract

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&rsquo; 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.

Highlights

Mongolia is a rich country with different kinds natural organic raw materials including oil, coals, oil shale, wood and bioorganic materials of animal origin such as casein, animal bone and huge amounts of wastes of wood and plants origin and plastics and so on (Purevsuren et al, 2017)
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
These results show that the yield of tar, pyrolysis water and gas increased with raising the temperature of pyrolysis

Summary

Introduction

Mongolia is a rich country with different kinds natural organic raw materials including oil, coals, oil shale, wood and bioorganic materials of animal origin such as casein, animal bone and huge amounts of wastes of wood and plants origin and plastics and so on (Purevsuren et al, 2017). Pyrolysis is an efficient method of treatment of organic material at elevated temperatures in the absence of oxygen It involves the simultaneous change of chemical composition and physical phase during thermochemical decomposition of organic material by heat and is irreversible (Davaajav & Purevsuren, 2006). We are working on pyrolysis of some organic raw materials including different rank coals (Avid & Purevsuren, 2002; Munkhjargal & Purevsuren, 1998), oil shale (Avid, Purevsuren, & Dugarjav, 2000; Purevsuren & Ochirbat, 2016), wood waste (Otgonchuluun, Ariunaa, & Purevsuren, 2015), animal bone (Davaajav & Purevsuren, 2006; Purevsuren, Avid, Narangerel, Gerelmaa, & Davaajav, 2004), shell (Purevsuren, 2012), polypropylene waste (Purevsuren, Davaajav, Karaca, et al, 2009), milk casein http://ijc.ccsenet.org. (Purevsuren & Davaajav, 2001b, 2001a), and characterization of obtained hard residue, tar and gas product after pyrolysis
