ORACLE: Odorant RemovAl by Chemical Looping dEsulphurisation

这项拨款的工作将着眼于在过程中使用氧载体，以协助从天然气中去除气味化合物。添加气味剂是为了通过气味来检测气体泄漏，然而，它们给不耐硫的天然气的任何用途带来了问题。特别是燃料电池使用的催化剂被硫灭活。因此，在天然气可以用于这些系统之前，有必要去除异味。氧载体利用固体材料中的氧气来燃烧物质，然后可以与空气一起再生。我们将研究各种载氧材料对含硫化合物燃烧的选择性和效率。如果发现这个过程是合适的，那么可以在一个系统中使用，该系统首先将硫化合物燃烧成二氧化硫，以便通过标准方法将其除去。

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.
