Adsorption

Adsorption is the process by which particles, e.g., solvent molecules, become attached to a solid adsorbent. Pressure, temperature and the chemical conditions determine the process of adsorption.

Catalysis

The principle of catalytic combustion was discovered in the 19th Century by the Jena chemistry professor Johann Wolfgang Döbereiner. 1823 he developed, based on his findings, a catalytic lighter. Since then, the catalysis made ​​its way in different areas, often unnoticed.

On adsorption isotherms

The mathematical description of the equilibrium of adsorption is referred to as adsorption isotherm. The adsorption isotherm permits a first estimate of whether an adsorbing agent is suitable for a particular process.

Adsorptive exhaust treatment; kinetics and mass transfer zone

The design of a working adsorber must consider more factors than the adsorption isotherm. Information on the time process of the adsorption is also important.

Introduction

Catalysis is a method for acceleration and control of chemical reactions. The phenomenon was discovered 200 years ago. Today, catalysis is used in numerous technical applications.

Fundamentals

A catalyst facilitates, accelerates or controls a chemical reaction without being consumed.

Fundamentals

An aerosol is a suspension of particulate in a gas. The particles are so low in weight that they settle very slowly even if the gas is at rest.

Aerosols in exhaust treatment

Aerosol, whether containing solid or liquid particles, are not retained by adsorption systems.
