Catalyst and process for the selective oxidation of hydrogen sulphide to elemental sulphur. |
| 摘要 |
<p>Catalyst (I) has a specific surface area above 20 sq.m/g, average pore radius of 25 Angstroms at least with no activity w.r.t. the Claus reaction. (I) may be supported e.g. on SiO2. Active component in (I) is pref. an iron and/or chromium cpd. plus a phosphorus cpd. promotor. H2S contg. gas and O2 contg. gas are passed over (I) in a fixed or fluid bed at below 300 deg.C to obtain elemental sulphur.</p> |
