Summary on Grant Application Form
Adsorption is a major separation process in the chemical industry. This is because of the wide range of adsorbents available, including molecular sieves and activated carbons. One type of zeolite is used for the separation of air into nitrogen and oxygen. Nitrogen is used as an inert gas to prevent unwanted reactions; oxygen is commonly used in medical applications. In recent years, adsorption has been increasingly used in environmental applications, such as the separation of carbon dioxide from exhaust gases, ammonia from foundry air and methane from landfill gas.In order to test new adsorbents, investigate new applications and design new processes, it is necessary to carry out experiments involving adsorption. These are relatively straightforward for pure-components and can be achieved from pressure measurements or a sensitive balance which measures the mass adsorbed. However, it is much more difficult to deal with mixtures because the individual components interfere with each other and there is no direct way of calculating the amount adsorbed of each component. If the amounts adsorbed are sufficiently different then the adsorbent is capable of achieving a separation.The amounts adsorbed in the mixture are actually inferred from measuring the composition of the gas mixture in contact with the adsorbent. For example, imagine that we would like to separate a 50% mixture of components A and B. The mixture is allowed to come into contact with an adsorbent. Some time later, the composition of the gas phase is 80% A. From the gas-phase composition we can tell that component B is preferentially adsorbed. This proposal is concerned with how best to measure the composition of gas mixtures, and the development of a universal detector.
