Abstract

In the Boreskov Institute of Catalysis in cooperation with specialists of All-Russian Institute of Hydrocarbons Raw Materials novel methods of purification of fossil fuels based on oxidation of hydrogen sulfide to elemental sulfur have been developed. In this paper the results of laboratory and pilot plant testing of the technologies are presented.

Highlights

Hydrogen sulfide is known as one of the most toxic atmospheric pollutants
That is why the problem of the development of environmentally friendly technologies of utilization of hydrogen sulfide containing gases resulting from fossil fuels extraction and processing is a challenge to the world community
A few years ago in the Boreskov Institute of Catalysis the technology of hydrogen sulfide direct catalytic oxidation in a fluidized catalyst bed, that has no restrictions on H2S concentration has been developed

Summary

Introduction

Hydrogen sulfide is known as one of the most toxic atmospheric pollutants. Acid rains, depression of vegetation, dying of aqueous flora and fauna, increase in respiratory and oncological diseases are typical consequences of the adverse effect of hydrogen sulfide and toxic products of its processing, such as sulfur dioxide, carbon oxide-sulfide, carbon disulfide. A few years ago in the Boreskov Institute of Catalysis the technology of hydrogen sulfide direct catalytic oxidation in a fluidized catalyst bed, that has no restrictions on H2S concentration has been developed. A raw hydrogen sulfide containing gas is supplied to the reactor with a fluidized bed of catalyst, simultaneously oxygen (or air) is fed into the catalyst bed by a separate flow.
