Desulfurization Catalyst containing Zinc Oxide Nanoparticles

Introduction

Sulfur compounds are one of the main pollutants of the air and chemical processes which damage human health, water resources, catalysts and other devices. Removing sulfur compounds is one of the main processes in fossil fuel applications. Various inorganic sorbents are used to remove H2S in such applications. Among sorbents, zinc oxide is one of the most important sorbents for removal of H2S at moderate temperatures. This advantage is due to the fact that the thermodynamics of the ZnO-H2S reaction is more favorable than other desulfurizing sorbents and also has a higher sulfur absorption capability. Nanotechnology, relying on its unique features, has improved the performance and properties of the products.
