ORACLE: Odorant RemovAl by Chemical Looping dEsulphurisation

这项资助的工作将着眼于在工艺中使用氧载体来帮助从天然气中去除有气味的化合物。添加气味剂是为了通过气味检测气体泄漏，然而，它们对任何不耐硫的天然气的使用都造成了问题。特别是使用被硫钝化的催化剂的燃料电池。因此，在天然气可以用于这些系统之前，必须去除气味剂。氧载体使用固体材料中的氧来燃烧物质，然后可以用空气再生。我们将研究各种氧载体材料对含硫化合物燃烧的选择性和效率。如果发现该方法是合适的，则可以在首先将硫化合物燃烧成二氧化硫的系统中使用该方法，以便可以通过标准方法将其去除。

Work in this grant will look at the uses of oxygen carriers in processes to assist in the removal of odorant compounds from natural gas. The odorants are added so that leaks of gas can be detected by the smell, however, they pose problems for any use the natural gas which is not tolerant of sulphur. in particular fuel cells use catalysts which are deactivated by sulphur. It is therefore necessary to remove the odorants before the natural gas can be used in these systems. An oxygen carrier uses oxygen held within the solid material to burn a substance, and can then be regenerated itself with air. We willlook at the selectivity and efficiency of various oxygen carrier materials towards the combustion of sulphur containing compounds. This process, if found to be suitable can then be used in a system which first combusts the sulphur compounds to sulphur dioxide so that it can be removed by standard methods.
