Abstract

In the given work oil residue, the oil sludge of Zhanaozen field and soot obtained during the combustion of propane-butane mixture with applying an electric field were selected among various types of natural materials to obtain porous carbon material (PCM). The PCMs obtained were used as a catalyst-carrier. The result of the research is synthesized multiwall nanotubes (MWNT), the identification of which is confirmed by the study of Raman spectra of the obtained samples. The search for new methods of creating catalytic systems (catalyst/carrier), which allow controlling the structure of carbon particles is an important problem, the solution of which may lead to the development of the approaches to the synthesis of carbon nanotubes (CNTs) with specific functional properties.

Highlights

The total world production of porous carbon materials is, currently, about 1millon tons per year and it continues growing
Oil sludge and soot obtained during the combustion of propane-butane mixture can be as cheap raw materials
Raman spectroscopy allows obtaining the information about purity, defects, and mutual alignment of carbon nanotubes (CNT) and it helps to distinguish nanotubes from other carbon allotropes

Summary

Introduction

The total world production of porous carbon materials is, currently, about 1millon tons per year and it continues growing. The main practical applications of PCMs are the systems of adsorption purification and separation of gas and liquid media. The application of PCMs as hemosorbents, carries for catalysts, adsorbents for chromatography, systems of the storage of gases and etc. The urgent problem is the development of new methods to obtain porous carbon materials with a required set of properties from cheap types of raw materials. Oil sludge and soot obtained during the combustion of propane-butane mixture can be as cheap raw materials. The activated carbons have been prepared by carbonization of precursors, i.e., raw materials with subsequent activation by physical treatment and/or chemical treatment. Most commonly employed activation methods are divided into physical and chemical activations. Most commonly employed activation methods are divided into physical and chemical activations. [3]
